Activity_ Structural Concept Name: Jintao Huo Case study building name: MSLE 1, Description/classification of structural systems a) Foundation & footings Reinforce concrete slab (a small gap under concrete slab) b) Primary structure( horizontal and vertical) Reinforce concrete slab (horizontal) Brick wall (vertical) Concrete wall (vertical) Beam (horizontal) Lintel (horizontal) (some lintels are primary structure, others are secondary) c) Secondary structure (Horizontal and vertical) Ramp support (horizontal) Lintel (horizontal) 2, Graphic structural diagrams (structural system to be clearly shown) a) Reinforce concrete slab.
b) Primary structure (horizontal and vertical) Reinforce concrete slab (diagram is shown above) Brick wall (vertical)
Concrete wall
Lintel
c) Secondary structure (horizontal and vertical) Ramp supports
3, Identification, description and location of structure of structural materials a) Concrete Concrete is fix by cement water and fine. Main material uses, it uses at foundation system, whole floor is made by concrete. b) Brick Bricks are made by Bricks are used for wall at this section. Brick is a block or a single unit of ceramic material. c)Timber Timber is wood beam, mainly use for floor of the ramp in this section. d) Steel beam Steel beam is made by steel, mainly use to hold timber for the ramp in this section. e) Zinc plane Zinc plane is made by zinc, mainly use for the shell for whole section.
Zinc plane is used for the top of ground floor. 4, Identify 3 structural joints It’s hard to take photo for tracing paper because they are not clear. So I use the pictures from map. a) Pin joint.
b) Fixed joint
c) Roller joint No roller joint for this section 5, Identify and explain the use of different structural fixings (weld, concrete, bolt, screw, nail) a) Bolt Bolts are used many times for this section. For example,
b) Screw Screws are used to fix two things together. For example, screws use to fix zinc plane and brick wall together.
c) Plastic (not sure) From my observation, I saw some black plastic uses at the connections between old buildings and new.
6, Sustainability and environmental analysis a) Carbon footprint I think the wood materials should be the least carbon footprint materials. (unknown writer, 2013)But normally wood doesn’t use for long term buildings, because wood building easy get fire and water.
b) Embodied energy “The embodied energy (carbon) of a building material can be taken as the total primary energy consumed (carbon released over its life cycle). This would normally include (at least) extraction, manufacturing and transportation” ( greenspec , 2013)
Metal have higher embodied energy then brick then concrete then wood. c)Recyclability Steel can easily recycle and reshape. Bricks can recycle as well if they are whole. If wood is under good protection, it can recycles as well. 7, Economical implications of decisions My father is a civil engineer in China. He tells me that concrete is the cheapest material, because we can make it by ourselves. Steel is expense, but we can sell them in the future when we remove the building. He doesn’t like use wood, because they are expense and normally can’t recycle.
