Week 5 This week we looked at our drawing plans again for our chosen sites and completed a ‘Structural Xray’ of our building, which we looked at the structural systems in our case study, and answered questions on them. The questions were as follows… 1) A) The foundations of the building consisted of reinforced concrete piers, which anchored the building into the ground. On top of this was a concrete slab, which formed the base of the building. b) the primary structure consisted of vertical pre-cast concrete panels that formed the walls of the structure. As well as this we had the concrete slab as the foundation. c) The secondary structure consisted of horizontal galvanised steel members and pine timber beams which form part of the roofing and ceiling of the structure.
2) A) this image shows the location of the concrete piers which form the footings…
B) This shows the primary structure members and their locations…
c) this image is of the secondary structure members, where the different letters differentiate between the timber pieces needed and the steel used…
3) A) The structural materials included: concrete, in the form of pre-cast (P1) panels, and as footings and slab material, commonly with the dimensions 150 x 75mm
B) steel was another material, in the form of framing and column supports, as you can see in the photo (CP2), mainly in the form of 250UB31
c) a third material used was the timber members. These formed the canopy of the building and the rafters (PC2). The two most common measurements were 130 x 45mm, and 300 x 45mm
4) A) the first joint is a footing to pre-cast panel junction, this is a very complicated jointâ€Ś
B) another junction is using a stich plate to join the two pre-cast panelsâ€Ś
c) a third joint is connecting the steel member to the pre-cast panelsâ€Ś
5) A) Weld: welding is joing two metal pieces together using heat to melt the faces of the two members, and letting them cool whilst connected, therby binding them. It is commonly used with joining two steel members in an ‘L’ shape joint B) concrete: a building material made from crushed stone, sand, cement and mixed with water that can be poured over/into something and solidifies as a solid ‘rock’. This is commonly used for laying paths or footings to a building as it can be easily levelled and is a stable surface c) bolt: a bolt is a metal pin like building material. These are used to connect two pieces of material together, eg two pieces of timber d) screw: similar to a bolt, it has a helical thread running along it and can be drilled into pieces of timber to connect them and the helical thread eats into the timber and tightens. e) Nail: a nail is again similar to a bolt, it has a sharp point at one end and a head at the other. A hammer is used to drive the point of the nail through materials. Commonly used to attach two small pieces of wood together as it doesn’t have the same strength as a screw. 6) A) Carbon Footprint: Carbon Footprint is define by Dictionary.com as “the amount of carbon dioxide or other carbon compounds emitted into the atmosphere by the activities of an individual, company… ect”. (Dictionary.com 2013) b) “The quantity of energy required by all of the activities associated with a production process, including the relative proportions consumed in all activities upstream to the acquisition of natural resources and the share of energy used in making equipment and in other supporting functions i.e. direct energy plus indirect energy.” (EMBODIED ENERGY 2013) c) Recyclability is “The ability of a product or material to be recovered or otherwise diverted from the solid waste stream for the purpose of recycling” (BuildingCTGreen 2013). 7) This terms is put simply, the amount of money needed and the amount of money generated. The decision to extend Queen’s College is a decision made by the administrators of the college in order to ultimately generate more money. The more space they have in their college, and the more upmarket it looks, the more customers they will attract, and thus the more income they can generate.
