TB-354 Select Beam Design Tables - Weyerhaeuser Beam Design Tables ... (NBC) 2015 and the Ontario Building Code (OBC) 2012. ... Minimum Bearing Length Adjustment for SPF Plate

TECHNICAL BULLETIN

TB-354 March 2017 (Expires 3/2019)

Select Beam Design Tables The following information is intended to assist building designers and/or building officials in selecting appropriate Trus Joist® beam products. The tables have been drafted to be similar to the span tables found in Part 9 of the National Building Code of Canada (NBC) 2015 and the Ontario Building Code (OBC) 2012. It is the responsibility of the building designer and/or building official to confirm the conditions of the beam to be within the limitations of these tables.

The tables included in this technical bulletin provide maximum load solutions for select 1.55E TimberStrand® LSL and 2.0E Microllam® LVL. The member widths considered are 1 ¾″, 3 ½″, 5 ¼″, and 7″. The member depths considered are 9 ½″ and 11 ⅞″. The tables encompass four different design loads. For each design load, three different load configurations are considered. The first load configuration involves only a uniformly distributed load. The second and third load configurations involve a standardized uniformly distributed load combined with a single concentrated load that is located within a specific region along the beam span.

It is important to note that the values in these tables apply to only simple span beams. For continuous spans, cantilevers, and other applications, use Forte® software by Weyerhaeuser. For additional design information, including multi-ply connections, please reference Specifier′s Guide for Trus Joist® Beams, Headers, and Columns (Canada-East: TJ-9500 \ Canada-West: TJ-9505). Should the building designer and/or building official have any questions, please contact your local Weyerhaeuser representative.

Design Example

A design example is provided on page 16. The design example considers two (2) beams with unique loading conditions. It is intended to help interpret the tables and encourage ease of use for building designers and/or building officials.

The content within a cell varies depending on the load configuration. The figures below illustrate the type of information contained within a cell for each general load configuration.

UNIFORMLY LOADED BEAMS

CONCENTRATED LOAD (DESIGN LOAD AREA) FOR BEAMS

Minimum Bearing Length Adjustment for SPF Plate

The tabulated values for supported length, concentrated load, and/or design load area assume the beam is bearing on either an SPF column (No. 2 or better) or 2x4 SPF plate (3.50″ maximum plate width). If the actual value for supported length, concentrated load, and/or design load area is less than the tabulated value, the minimum bearing length for SPF plate may be reduced. For the supported length tables, the reduced minimum bearing length (𝐿𝐿𝑏𝑏′ ) is a product of the load ratio and tabulated minimum bearing length. For the concentrated load tables, the equation for reduced minimum bearing length is given in the table below. It is important to note that the minimum bearing length for all Trus Joist® beam products is 1.50″ regardless of the load conditions.

Table Footnotes

MAXIMUM SUPPORTED LENGTH FOR UNIFORMLY LOADED BEAMS

[1] Table values apply only to simple span beams with full lateral support of the compression edge. - Deflection criteria = L/360 live load (LL); L/240 total load (TL). - Simple span means a total of two bearing points, located at the ends of the member (i.e. no cantilevers). Beams/joists that run continuously over three or more supports are not simple span.

[2] Column minimum bearing lengths assume column member is SPF No. 2 or better. Plate minimum bearing lengths assume plate member is SPF (fcp = 5.3 MPa = 768.7 psi).

[3] Refer to Specifier′s Guide TJ-9500 (Canada-East) \ TJ-9505 (Canada-West) for complete design and installation information. [4] Supported Length applies only where the floor supports residential areas as described in NBC 2015 Table 4.1.5.3 and OBC

2012 Table 4.1.5.3; or the loading does not exceed the values specified in the load diagram above the table. [5] Supported Length is half the sum of the joist spans on both sides of the beam; joists must be simple span.

MAXIMUM CONCENTRATED LOAD (DESIGN LOAD AREA) FOR BEAMS – END-SPAN TO QUARTER-SPAN


[2] Location (x) of concentrated load: inside face of support ≤ x ≤ quarter-point of clear span (i.e. shaded region in load diagram above table).


[4] Refer to Specifier′s Guide TJ-9500 (Canada-East) \ TJ-9505 (Canada-West) for complete design and installation information. [5] Beam also supports a maximum 24″ floor tributary load as described by the load diagram above the table. [6] Design Load Area is in reference to floors supporting residential areas as described in NBC 2015 Table 4.1.5.3 and OBC 2012

Table 4.1.5.3; or the loading does not exceed the values specified in the load diagram above the table.

MAXIMUM CONCENTRATED LOAD (DESIGN LOAD AREA) FOR BEAMS – QUARTER-SPAN TO MID-SPAN


[2] Location (x) of concentrated load: quarter-point of clear span ≤ x ≤ midpoint of clear span (i.e. shaded region in load diagram above table).


[4] Refer to Specifier′s Guide TJ-9500 (Canada-East) \ TJ-9505 (Canada-West) for complete design and installation information. [5] Beam also supports a maximum 24″ floor tributary load as described by the load diagram above the table. [6] Design Load Area is in reference to floors supporting residential areas as described in NBC 2015 Table 4.1.5.3 and OBC 2012

Table 4.1.5.3; or the loading does not exceed the values specified in the load diagram above the table.
