LYSAGHT FIRMLOK® STRUCTURAL BEAMS
1.1 FIRMLOK® STRUCTURAL BEAMS FIRMLOK® structural beams consist of two interlocking C-sections. They are light, strong and universal in their application. A range of connection types and accessories allows you to erect your project with ease.
FIRMLOK® is uniform in quality, it doesn’t warp or split and it doesn’t need painting. Consistent straightness simplifies alignment. LYSAGHT FIRMLOK® beams are available in three sizes 100mm, 150mm and 200mm deep depending on your application and aesthetic preference.
This publication demonstrates FIRMLOK® in its application as roofing members, combined with our range of roof sheeting. Typical applications include patios, carports and awnings.

1.3 FIRMLOK® QUICK SELECTION TABLESINTRODUCTION
FIRMLOK® “Quick Selection Tables” provide an easy tool for determining the roof layout of your structure, using FIRMLOK® beams and lysaght cladding.
This guide is divided into sections: Cladding Selection, Flat Structures and Pitched Structures. Each section comprises of diagrams and span tables. The diagrams assist with selecting your structure type and the tables determine the size of each member based on loading.
When using the Quick Selection Tables, member designation is important.
• Purlins run at 90° to the ribs of your cladding and the cladding is screwed to them.
• Rafters generally run parallel to the ribs on your cladding and have purlins attached
• Headbeams support the upper and lower edge of the roof and are supported by posts.
USING QUICK SELECTION TABLES
The Quick Selection tables have been developed to be comprehensive and flexible, whilst remaining easy to use. The three sections allow you to design most typical structures with little effort.
Note: The sections for free-standing structures can be used to design similar attached structures, provided correct design of attachment to existing structure is performed.
To begin, you will need to determine:
Structure Type (Flat or Pitched): This will indicate which section of the “Quick Selection Tables” is appropriate to your design.
Wind classification (N1, N2, N3 or N4) and wind blocking: It is important to know the wind class for your area and structure. Refer to Australian Standards AS4055 - 2012 Wind loads for housing for wind classification. Alternatively, seek guidance from a qualified engineer or builder.
Structure size: The structure size is the overall width and length of the intended structure in plan view.
This is all the information you need to begin designing your structure. An experienced user will have no problems using the tables to design each structure. You may wish to refer to the example at the end of each section.

1.4 DESIGN CONDITIONS AND NOTES FOR THE TABLES GENERAL
This document is an engineering aid to help in the design of carports, awnings and patio covers by designers. This document gives all the information to design an economical structure based on the wind classification, wind blocking and geometry of the structure.
DESIGN STANDARDS
FIRMLOK® “Quick Selection Tables” have been prepared in accordance with the appropriate Australian Standards. Cladding, beam and connection capacities are based on limit state design and testing at LYSAGHT® Research and Technology. The following standards have been referenced:
• AS/NZS 4600: 2005 Cold formed steel structures
• AS/NZS 1170.0 - 2002 Part 0: General principles
• AS/NZS 1170.1 - 2002 Part 1: Permanent, imposed and other actions
• AS/NZS 1170.2 - 2011 Part 2: Wind Actions
• AS 4055 - 2012 Wind loads for housing
• AS 1562.1 - 1992 Design and installation of sheet roof and wall cladding Part 1: Metal
• AS 4040.2 - 1992 Methods of testing sheet roof and wall cladding – Resistance to wind pressure for non-cyclonic regions
• NCC - Building code of Australia (BCA) (current edition)
WIND
The tables presented in this brochure are for attached/freestanding awnings and pitched structures in normal wind (non-cyclonic) for wind classifications N1, N2, N3 and N4.
Design Wind speeds and wind pressure coefficient factors used to calculate the design net pressures have been derived from AS/NZS 1170.2-2011: Structural Design Actions Part 2: Wind Actions. For residential application, the wind classification system from AS 4055-2012: Wind Loads for Housing has been adopted for user convenience. For each structural configuration, five wind loading situations have been considered:
1B - one side blocked, typically attached to one side of an existing house or 0/4 sides blocked.
2B - two sides blocked, typically attached to two sides of an existing house
3B - three sides blocked, typically attached to three sides of an existing house; a "U" shaped configuration.
The structures with flat roof must have a roof slope greater than 2 degs and no greater than 10 degrees. Roof slopes higher than 10 degrees may experience greater wind loads than used in the design. Pitched roofs have been designed for 15 and 22.5 degrees.

LOADS
The structure is designed for the following loads:
• Wind Loads: as described above.
• Dead Loads: Self weight of both sheeting and FIRMLOK® beam have been considered. No allowance for ceilings or other dead loads uniformly distributed or point loads have been made.
• Live Loads: A Live Load of 0.25 kPa has been considered on the beams. A concentrated live load of 1.1kN factored up, has been considered on each beam individually.
DEFLECTION
Deflection limits adopted for the design of FIRMLOK® beams are:
• Dead Load: Span/300 for beams with a maximum of 20mm
• Wind Load: Span/150 for serviceability wind pressure
• Live Load: Not Applicable
ATTACHED AND FREESTANDING AWNINGS
The capacity of the existing structure to withstand the additional loads arising from the attached awning must be verified by a competent person, an engineer or builder. It’s advised to check with your local government authority to determine any specific requirements or rules for the attachment to existing structures.
Awnings have not been designed to account for any additional rainwater runoff, other than that falling directly onto its roof area. Rainwater must not be distributed from existing roofs onto the awning.
The quick selection tables have been created based on design and tested using LYSAGHT® components.
CONNECTIONS FOR STRUCTURES
When a beam is designed for strength, the connection at the ends of the beam must be checked against its strength. There are several connection types which are considered in the span tables. Beams are always connected to each other with FIRMLOK® universal connectors. These brackets connect to the beams basically with a bolt and one or two teks to the supported beam or post.
Bolts are used on the beam to beam connectors to distribute the load to the two sides of the supporting beam. The bolts are used with the post to take the higher loads from big spanning beams. The connection capacities for beams are based on a member supported by a member of the same size. If the supporting member is bigger the connection capacity may be stronger than indicated in the tables.
There are two main types of connections for beams to posts: Post behind beam using bolts and Post to side of beam using brackets. The connection capacities are based on extensive testing at our NATA registered laboratory.
For pitched structures, portal frame rafter and collar-tie truss frames and their immediate supports (e.g. post, existing structure etc.) are assumed to be connected as simple, moment free pinned connections.
Portal frame rafters are assumed to be laterally restrained by purlins only at eave, apex and internally where indicated on the relevant diagrams.

2.1 CLADDING SELECTION• The tables presented in this section are for non-cyclonic
conditions only.
• Wind Loads: Design Wind speeds have been based on the classification system used in AS4055:2012. Factors used to calculate the design net pressures have been derived from AS1170.2:2011. Five wind blocking cases relevant to home improvement structures have been considered.
• Flat roofs must have a roof slope no greater than 10 degrees and no less thaan 2 degrees. Roof slopes beyond 10 degrees may experience greater wind loads than have been designed for. Refer to the minimum roof pitch table.
• Pitched roofs have been designed for two slopes, 15 and 22.5 degrees.
• Dead Loads: Self weight of sheeting only has been considered.
• Live Load: No general live load has been used. As the sheet spans are for ‘No Foot Traffic’, i.e. no person is allowed to walk on the sheeting. Where spans have been reduced for foot traffic, the sheeting has been tested for a person weighing up to 110kg. Where the spans are used for no foot traffic, a sign should be attached to the inside of the beams.
The tables give the spans for wind pressure, termed “foot traffic - NO” and the span for foot traffic, termed “foot traffic - YES”. The sheeting has been tested in accordance to AS 4040.2 with serviceability deflection limit of Span/120 + Fastener Pitch/30. LYSAGHT FLATDEK® cladding spans may result in noticeable deflections under maximum loads. In situations where deflections are deemed critical, spans should be reduced to the walkable spans e.g. in a screen room.
NON-CYCLONIC AREAS
The information in this section for cladding is suitable for use only in areas where a tropical cyclone is unlikely to occur as defined in AS 1170.2:2011.

* To achieve 1.5° pitch,it is recommended to build a gutter around the perimeter of the flat roof.
** These spans are only applicable for overhanging sheets attached with a gutter or an angle stiffener.
For gutter and roof maintainence, always walk on the support beams, do not walk on the sheets overhang or use the overhang sheets as support. See diagrams below. Maximum roof pitch for a flat structure is 10°. The maximum span for maintenance foot traffic on sheet overhang is 100mm for all sheets.

Notes:
1. All spans are in mm.
2. The “No Foot Traffic” span range is designed for the condition where no person is allowed to walk on the roof. The design criteria includes deflection due to self weight, maximum wind pressure and fastener capacity based on FIRMLOK® beams. A sticker must be placed on the supporting beams which has the No Foot Traffic sign on it.
3. The ‘FOOT TRAFFIC’ spans were derived from testing carried out for home improvement type structures only. The foot traffic spans have been tested for a person with a weight up to 110kg. This design criteria is different to the testing criteria in AS 4040.1:1992.
4. The above tables can be used for sheets with bigger thickness of the same LYSAGHT® profile and material specification.
5. All sheeting materials are G550 grade steel with COLORBOND® or ZINCALUME® steel.
6. For cladding with foot traffic, use the smaller of the two spans given in the tables (YES = foot traffic, NO = no foot traffic ).
7. For more details on LYSAGHT® claddings, refer to the individual product brochures by visiting www.lysaght.com.
8. *KL700HS, if sheet span ≥ 2400mm, provide 1 rivet/screw at the side-lap at mid-span to keep sheets together. *TRIMDEK® & SPANDEK®, if sheet span ≥ 2000mm, provide 1 rivet/screw at the side-lap at mid-span to keep sheets together. *CUSTOM ORB®, if sheet span ≥ 1500mm, provide 1 rivet/screw at the side-lap at mid-span to keep sheets together.

Notes:
1. All spans are in mm.
2. The “No Foot Traffic” span range is designed for the condition where no person is allowed to walk on the roof. The design criteria includes deflection due to self weight, maximum wind pressure and fastener capacity based on FIRMLOK® beams. A sticker must be placed on the supporting beams which has the No Foot Traffic sign on it.
3. The ‘FOOT TRAFFIC’ spans were derived from testing carried out for home improvement type structures only. The foot traffic spans have been tested for a person with a weight up to 110kg. This design criteria is different to the testing criteria in AS 4040.1:1992.
4. The above tables can be used for sheets with bigger thickness of the same LYSAGHT® profile and material specification.
5. All sheeting materials are G550 grade steel with COLORBOND® or ZINCALUME® steel.
6. For cladding with foot traffic, use the smaller of the two spans given in the tables (YES = foot traffic, NO = no foot traffic ).
7. For more details on LYSAGHT® claddings, refer to the individual product brochures by visiting www.lysaght.com.
8. *KL700HS, if sheet span ≥ 2400mm, provide 1 rivet/screw at the side-lap at mid-span to keep sheets together. *TRIMDEK® & SPANDEK®, if sheet span ≥ 2000mm, provide 1 rivet/screw at the side-lap at mid-span to keep sheets together. *CUSTOM ORB®, if sheet span ≥ 1500mm, provide 1 rivet/screw at the side-lap at mid-span to keep sheets together.

3.1 QUICK SELECTION TABLESThere are several tables based on the type of member and the way it is loaded together with the connection at the end of the beam. The tables are used to give the span of FIRMLOK® beams for different wind classifications and wind blocking based on the applied load and the load width. The table is organised as shown below:
HEADBEAM OVERHANG
Headbeams can have overhang and are tabulated for beams supporting sheeting only. A bolted post behind connection must be used to overhang the headbeam past the supporting post. The headbeam span must be the span shown in the diagram to get the strength of the beam. With this span the post can be moved in creating the overhang. This distance can only be up to the span/4 (one quarter of the span). The maximum overhang each beam can have is given in the overhang table.

3.7 DESIGN EXAMPLES: FLAT STRUCTURESEXAMPLES
There are two examples given to show the procedure for designing an awning. Example 1 is a simple attached awning which uses the long spanning capability of FLATDEK® to provide a structure with minimal FIRMLOK® beams.
Example 2 is a bigger freestanding carport with purlins, rafters and headbeams. It has 2 different solutions to illustrate different choices in the awning design configuration.
GENERAL NOTES
The following design parameters are required:
DIMENSIONS
Work out the relevant length, width and height for your structure.
WIND CLASS
Refer to AS4055 or consult your local building authority, engineer or builder to determine if the Wind Category is N1, N2, N3, etc. Refer to the ‘Lysaght Design Guide for Wind’.
WIND BLOCKING
From site condition, determine wind blocking (0,1,2,3,4 sides blocked) as defined in Section 1.4.
BEAM CONNECTIONS
Refer to the key diagram and connection details, see different ways to connect FIRMLOK® beams to a support.
ROOF CLADDING
Refer to the cladding selection portion of this guide for claddings and spans. Check sheet overhang if required. Cladding overhang and gutter width must be included in load width calculation when determining beam size and span
Try out different beam sizes, number of beams and connection types to find the most suitable arrangement for your structure. Interpolation between values of the same category is allowed, in the following examples. For simplicity, the next higher value is used.
Follow the Guide for the design process detailed here.

EXAMPLE 1:
A SIMPLE FLAT AWNING ATTACHED TO THE BACK OF AN EXISTING DWELLING.
Design parameters:
• Wind Class: N3 (W41N)
• Wind Blocking: 1 side blocked
• Projection: 4200
• Width: 6200
• Cladding: No foot traffic, No overhang
• Connection: Beam to side of post
STEP 1: SELECT CLADDING
Refer to roof sheeting span table for wind class N3, 1 side blocked. An economical solution is to try a long span sheeting like FLATDEK® so no purlins or rafters are required. FLATDEK® 0.42mm spans a distance of 4500mm for single/continuous span with no foot traffic, thus FLATDEK® 0.42mm can be used with only a headbeam for the awning. This is a “No Foot Traffic” solution.
STEP 2: DETERMINE BEAM LOAD WIDTH
Half the wind load on the sheeting is taken at the house and the headbeam.
The beam load width is calculated as follows:
Half sheet span 4200 / 2 = 2100, sheeting overhang = 0, total load width = 2100 + 0 = 2100 mm
STEP 3: DETERMINE BEAM SIZE
Refer to the Beam Table Index for the headbeam tables for 1 span simply supported with connection type: Beam to side of post; refer to Table 2A. For an awning width = 6200mm, headbeam load width = 2100 mm, wind class: N3 and wind blocking: 1 side blocked, the following beam spans are:
Beam Span (mm)
F100 4050 < 6200 Not OK
F150 6250 > 6200 OK
F200 7900 > 6200 OK
Minimum suitable beam size is a F150 beam; adopt a F150 for headbeam. Edge beams are optional at the sides of the awning; they don’t carry any load. For uniform appearance, use the same size edge beam as the headbeam; for minimum cost, use a F100 beam.
Posts:
The value next to the beam span in the tables is the reaction (load) at the end of the beam acting on the post. This value can be used to design the post. The wind uplift reaction on the post in this example is 5 kN. Please refer to post manufacturer’s data for post capacity.
STEP 4 DETERMINE ATTACHMENT LOAD
Use Table 5 to determine the load from the awning transferred to the attached structure. The attachment load is assumed to be uniformly distributed along the attached structure. The attachment load width: 4200mm/2 = 2100mm. For N3 & 1 side blocked, the attachment load is 1.5 kN/m. Use this load to check the attachment member e.g. receiver channel or beam, the fixings and the supporting structure e.g. wall or fascia and house rafters.
STEP 5 CONNECTION DETAILS
Since the Beam to side of post connection was chosen for the awning, refer to connection F6 for Beam to side of post corner detail and F9 for Beam to attachment detail.

EXAMPLE 2:
A SIMPLE FREE STANDING AWNING NEXT TO AN EXISTING DWELLING.
Design parameters:
• Wind Class: N3 (W41N)
• Wind blocking: 2 sides blocked
• Projection: 6000
• Width: 5000
• Cladding: SPANDEK® 0.42mm, Cladding overhang 0mm
• Connection: Use post behind beam
FREE STANDING AWNING
STEP 1: SELECT CLADDING
For this example, SPANDEK® 0.42mm was chosen. The cladding span tables for N4 wind with 1 side blocked shows that SPANDEK® can span 3000 mm. The awning projection is 5000 mm, hence the number of purlin spacings is: 5000 / 3000 = 1.67 i.e. 2 spaces; therefore try 1 intermediate purlin.
STEP 2: DETERMINE PURLIN SIZE
Refer to Table 1 to look up purlin size and span. The Load width for the purlin is 5000 / 2 = 2500 hence use 2700 mm without interpolation. In this example, at least 1 row of purlins is required. For N3 and wind blocking on 2 sides, the following single spans are:
Beam Span (mm)
F100 2600 < 6000 Not OK
F150 4100 < 6000 Not OK
F200 5850 < 6000 Not OK
For a single purlin span arrangement, no span is suitable. Let’s add an intermediate rafter to support the purlin and shorten the purlin span. Now the purlin span is 6000 / 2 = 3000. F150 can span 4100 > 3000 mm, OK.
Another possible solution is to add an extra row of purlins to reduce the load carried by each purlin. This will be explored as an option later.
STEP 3: DETERMINE RAFTER SIZE
Refer to the Beam Table Index for the rafter tables. For 1 span simply supported with a connection type: Post behind beam and supporting 1 row of internal purlins, refer to Table 3A.
Intermediate Rafter:
Awning width = 6000 mm, intermediate rafter load width = 6000 / 2 = 3000 hence use 3000 mm. For Wind Class: N3 and wind blocking on 2 sides, the following rafter spans are:
Beam Span (mm)
F100 2400 < 5000 Not OK
F150 3900 < 5000 Not OK
F200 5400 > 5000 OK
Minimum suitable rafter size is a F200 beam. Adopt F200 for the rafter.
End Rafter:
Awning width = 6000 mm, perimeter rafter load width = 6000 / 4 = 1500 hence use 1500 mm.
The available rafter spans are:
Beam Span (mm)
F100 3550 < 5000 Not OK
F150 5450 > 5000 OK
F200 7400 > 5000 OK
Minimum suitable rafter size is a F150 beam. For economy use a F150.
For universal appearance use a F200 beam since intermediate rafter size is a F200. The reaction is 3 kN.

STEP 2 DETERMINE PURLIN SIZE
Continuing from the end of Step 1 in the previous design, now try 2 rows of purlins with no intermediate rafter. Refer to Table 1 to lookup the purlin size and span. In this case the purlin load width is reduced to 5000 / 3 = 1667, hence use 1800 mm.
For N3 and 2 sides wind blocking, the following spans are.
Beam Span (mm)
F100 3200 < 6000 Not OK
F150 5050 < 6000 Not OK
F200 7050 > 6000 OK
The only suitable purlin size is a F200 beam; therefore adopt a F200 for the purlin.
STEP 3 DETERMINE RAFTER SIZE
For 1 rafter with connection type: ‘Post behind beam’ and supporting 2 purlins, refer to Table 3B. For awning projection = 5000, the rafter load width = 6000 / 2 = 3000, hence use 3000 mm.
For wind class: N3 and wind blocking: 2 sides blocked, the following rafter spans are:
Beam Span (mm)
F100 2650 < 5000 Not OK
F150 4200 < 5000 Not OK
F200 5900 > 5000 OK
The only suitable beam size is a F200 beam; therefore adopt a F200 for the rafter.

STEP 4: DETERMINE HEADBEAM SIZE
The front and back headbeams are supporting one internal rafter, therefore use Table 4A to find the beam size and span. Note this table is different to headbeam Tables 2A, 2B & 2C, because these tables are designed to only carry load directly from the sheeting. For N3 wind, 2 sides blocked and supporting 1 internal rafter with a span of 5000 mm (use rafter span = 5000 mm), the following headbeam spans are:
Beam Span (mm)
F100 2750 < 6000 Not OK
F150 4300 < 6000 Not OK
F200 6100 = 6000 OK
The only suitable headbeam size is a F200 beam; therefore adopt a F200 for the headbeam. The reaction is 8.5 kN.

The value next to the span in the tables is the reaction load acting on the support of the beam ie. the post. This value together with the load from the headbeam can be used to design the post and footings. The total uplift load on the post is: 8.5 + 3 = 11.5 kN.
This is conservatively high as the reaction load in the tables is for the maximum span of the beam. A more economical post and footing design can be considered by scaling down the reactions based on the ratio of actual span to maximum span; so the uplift load becomes:
3 x 5000 / 5450 + 8.5 x 6000/6100 = 11.1 kN (1.11 tonnes)
The post and footing should be designed for these loads and any horizontal wind loads.
STEP 5 CONNECTION DETAILS
Since a ‘post behind beam’ connection was selected for the awning, refer to Connection F4 for beam to beam details and connection F5 for corner details.

STEP 4 DETERMINE HEADBEAM SIZE
In this design, the head beams are not supporting an internal rafter. The headbeam load width is (5000 / 3) / 2 = 833, hence use min. 900mm. For N3 wind, 2 sides blocked, single span headbeam and ‘post behind beam’ connection, use Table 2B to find headbeam size and span.
The available choices are:
Beam Span (mm)
F100 4150 < 6000 Not OK
F150 6400 > 6000 OK
F200 9000 > 6000 OK
Minimum suitable headbeam size is a F150 beam. For economy, use a F150; for aesthetic appearances use a F200, since the rafter size is a F200.
Posts:
The post load is the same as in the previous example.
STEP 5 CONNECTION DETAILS
Since ‘Post behind beam’ connection was selected for the awning, refer to connection F4 for beam to beam details and connection F5 for the corner beam and post details.
DESIGN OUTCOME:
Note:
Since the purlin spacing is reduced, other claddings could be used. TRIMDEK® has a walkable span of 2000 and SPANDEK® has a walkable span of 1500. Both profiles can take the wind load so there is a choice of sheeting. Based on this, if the roof will be walked on for maintenance then TRIMDEK® should be used. If SPANDEK® is used then the “No Foot Traffic” sign should be fixed to the inside of the headbeams.

PART C4.0 Pitched Structures
4.1 TABLES FOR PITCHED STRUCTURESThere are 4 rafter load width tables for portal frame and collar-tie rafters for 15° and 22.5° roof pitches.
The tables are used to give the load width of FIRMLOK rafters for different wind classifications, wind blocking and rafter spans. Similarly 2 purlin span tables are provided for pitched structure using similar selection criteria.

4.5 DESIGN EXAMPLES: PITCHED STRUCTURESEXAMPLE 3:
A SIMPLE PITCHED ROOF FREESTANDING AWNING WITH 2 COLLAR-TIE FRAMES.
Design Parameters:
• Wind Class: N4 (W50N)
• Wind Blocking: 3 side blocked
• Building Projection (Rafter Span): 4800mm
• Building Width (Frame Spacing/Purlin Span): 4600mm
• Roof Pitch: 15°
• Cladding: FLATDEK® II, No foot traffic
• Connection: Rail behind post
STEP 1: SELECT CLADDING
Cladding span = 0.52x rafter span = 0.52x 4800mm = 2490mm. From roof sheeting span table for wind class N4, 3 side blocked, pitched roof and no foot traffic condition, FLATDEK® II 0.42mm can span up to 3000mm without intermediate support, which is suitable for this example.
STEP 2: DETERMINE RAFTER SIZE
For collar-tie truss with 15° roof pitch, use Table 6A to select rafter size and frame spacing. From step 1, we know FLATDEK® II 0.42mm can span between the eave and apex without intermediate support. So for wind class N4, 3 sides blocked, 4800mm rafter span (use 5000mm) and 0 row of intermediate purlin, the following collar tie truss load width are available:
Rafter Truss load width (mm)
F10011 1080 < 4600/2 Not OK
F15015 2200 < 4600/2 Not OK
F20020 2760 > 4600/2 OK
For an overall structure width of 4600mm, the load width of each end rafter frame is 4600/2 = 2300mm. therefore F20020 with load width of 2760mm is suitable for this case. The collar-tie strut size is F15015 for 150 or 200 rafters.
STEP 3: DETERMINE PURLIN SIZE
For 15° roof pitch, use Table 8A to select purlin size. With no intermediate purlin, the apex/rail purlin load width is 4800/4 = 1200mm, the following purlin spans are available.
Purlin Purlin span (mm)
F10011 3000 < 4600 Not OK
F15015 4650 > 4600 OK
F20020 6450 > 4600 OK
Since the collar-tie rafter size is F20020, therefore F15015 and F20020 are both suitable for apex purlins. The rail size should be F20020 as detailed on page 34.
STEP 4: CONNECTION DETAILS
For Apex connection refer to Connection detail P2. For Collar tie to rafter connection refer to detail P10. For rafter to post connection refer to detail P7. For Rail behind Post Connection refer to detail P6.

EXAMPLE 4:
A SIMPLE PITCHED ROOF FREESTANDING AWNING WITH 3 PORTAL FRAME RAFTERS.
Design Parameters:
• Wind Class: N3 (W41N)
• Wind Blocking: 1 side blocked
• Building Projection (Rafter Span): 4000mm
• Building Width: 10000mm
• Roof Pitch: 15°
• Cladding: CUSTOM ORB®, No foot traffic
• Connection: Rail to side of post
STEP 1: SELECT CLADDING
Cladding span = 0.52x rafter span = 0.52x 4000mm = 2080mm. From roof sheeting span table for wind class N3, 1 side blocked, pitched roof and no foot traffic condition, CUSTOM ORB® 0.42mm can span up to 1800mm < 2080mm, therefore provide 1 row of internal purlin between rail and apex, now the cladding span is 2080 / 2 = 1040mm < 1800mm, ok.
STEP 2: DETERMINE RAFTER SIZE
For portal frame rafter with 15° roof pitch, use Table 7A to select rafter size and frame spacing. It is unlikely that 2 frames will be able to support a building width of 10m. Therefore start design selection assuming 3 frames are required. Therefore the internal frame load width is 10,000mm / 2 = 5000mm and the end frame load width is 5000 / 2 = 2500mm. From step 1, we know CUSTOM ORB® 0.42mm requires 1 row of internal purlins. So for wind class N3, 1 sides blocked, 4000mm rafter span and 1 row of internal purlin, the following rafter load width are available:
Rafter Truss load width (mm)
F10011: 1850 < 5000, Not Ok
F15015: 5630 > 5000, Ok
F20020: 9000 > 5000, Ok
Therefore F15015 rafter is suitable for both end and internal frames. Collar-tie member is not required for portal frame rafter.
STEP 3: DETERMINE PURLIN SIZE
For 15° roof pitch, use Table 8A to select purlin size. With 1 intermediate purlin as determined from Step 1, the purlin load width is 1040mm (use 1200mm) and the purlin span is 5000mm, the following purlin spans are available.
Purlin Purlin span (mm)
F10011: 4850 < 5000, Not Ok
F15015: 7050 > 5000, Ok
F20020: 8750 > 5000, Ok
Therefore F15015 and F20020 are both suitable. The rail size should be F20020 as detailed on page 34.
STEP 4: CONNECTION DETAILS
For apex connection refer to connection detail P2. For rafter to post and post to rail connections refer to detail P5. For purlin connection refer to detail P3.
