1_DESCRIPTION / CLASSIFICATION OF STRUCURAL SYSTEMS

a) FOUNDATION & FOOTINGS

>Foundation - Shallow foundation; Used when the earth directly beneath a structure has sufficient bearing capacity to sustain the loads from the structure (Ching, 2008).

>Footings - Strip footing; the continuous spread footing of foundation walls (Ching, 2008).

b) PRIMARY STRUCTURE (HORIZONTAL AND VERTICAL)

>Primary structure- The building's primary structure consists of reinforced concrete, columns, beams and with continuous concrete slabs (Wikipato, 2013).

-Brick masonry load bearing wall (Vertical)

-Concrete bearing wall ---Vertical

-Concrete slab ---Horizontal

-Strip footing ---Vertical and Horizontal

-Lintel; A lintel can be a load-bearing building component, a decorative architectural element, or a combined ornamented structural item. It is often found over portals, doors, windows, and fireplaces (Wikipedia, 2013) --- Horizontal

-SHS roof beam (100*100*9) ---Horizontal

c) SECONDARY STRUCTURE (HORIZONTAL AND VERTICAL)

Secondary structure- the secondary structures as modifiable portions supported by primary structure (Kitamura, 1993)

-250 UB -250 PFC

-C section purlin; A purlin is any longitudinal, horizontal, structural member in a roof except a type of framing with what is called a crown plate (Wikipedia, 2013)

2_GRAPHIC STRUCTURAL DIAGRAMS (structural systems to be clearly shown)

b) PRIMARY STRUCTURE (HORIZONTAL AND VERTICAL)

c) SECONDARY STRUCTURE (HORIZONTAL AND VERTICAL)



3_IDENTIFICATION, DESCRIPTION AND LOCATION OF STRUCTURAL MATERIALS

4_IDENTIFIY 3 STRUCTURAL JOINTS (use tracing paper to sketch from the construction drawings)



5_IDENTIFY AND EXPLAN THE USE OF DIFFERENT STRUCTURAL FIXING (weld, concrete, bolt, screw, nail)



6_SUSTAINABILITY AND ENVIRONMENTAL ALAYSIS

a) CARBON FOOTPRINT

-Steel; Tonnes of CO2 emission per tonne of steel are 0.919, 0.762, 0.857, 1.35, 1.10 and plate, sections, tubes, purlins and rails respectively(Steelconstruction, 2013)

-Concrete; The carbon footprint of concrete is large because of two factors ; the energy used to heat limestone which is the one of the major components in concrete and the other one is CO2 emission from limestone (Science daily, 2013).

-Brick masonry wall - using exiting walls.

b) EMBODIED ENERGY

Steel and Concrete

-Masonry blocks - using existing walls

.

c) RECYCLABILITY

-Steel; The recycling rate of steel is roughly over 80% of any kind of steel such as Cladding, Floor decking, Purlins etc. (Tata steel, 2013)

-Concrete; 'Crushed concrete may be reused as an aggregate in new Portland cement concrete or any other structural layer. Generally it is combined with a virgin aggregate when used in new concrete. However, recycled concrete is more often used as aggregate in a sub-base layer.' (Concrete network, 2013)

-Masonry blocks

7_ECONOMICAL IMPLICATIONS OF DECISIONS

Using existing structure as much as possible for reducing budget.

Using appropriate material for cladding; Zinc instead of expensive material such as Titanium or Copper.
