1: Description/Classification of Structural Systems.

a) Foundations & Footings - For this site there were three different footings; Pad footings, Strip footings and Blinded trenches. Each of these had different thicknesses, load bearings and reinforcements. Sketches of a few examples from the plan are below.b) Primary Structure – The major materials in the structure that support it are part of the primary structure. An example is the concrete pillars.c) Secondary Structure – The fillings, or in other words the materials that are connecting the primary structure together but that take no load themselves.

4: Identify three Structural Joints.

a) This is a Mullion, it is a vertical bar that generally sits between panes of glass in a window. This one is fixed to brickwork and has a concealed spigot.

a

b) This is a continuous angle connector joining a glass block wall to the pre-fabricated frame.

5: Identify and explain the use of different Structural Fixings .

a) Weld - Section Detail 16 A8.12. Metal, melted and placed carefully so that it may act as a join between other parts when it cools. Strong in compression and reasonably strong in tension.

b) Concrete – Section Detail 7 A8.12. Heavy building material that is made up of aggregate, sand, cement and water, used generally to add strength to structures and can be precast or insitu. Strong in compression, weak in tension.

c) Bolt – Section Detail 5 A8.08. Metal, acts as a fastener to hold two or more objects together. Strong in compression and tension.

d) Screw – Plan Detail 1 A8.07. Metal fastener, Strong in compression, reasonably strong in tension as it will act similarly to a spring when bent.

e) Nail – Slim metal, acting as a fastener, reasonably strong in compression and weak in tension.

6: Sustainability and Environmental analysis.

a) Carbon Footprint:Steel – High CO2 emissions from production, but can be recycled reasonably easily.Concrete – The production of concrete produces as much CO2 as steel, however it is much harder to recycle and causes even more emissions to do so.Timber – Nearly no emissions, and can be very easily recycled if it isn’t rotten, however losing trees to use the timber does take its toll.Glass – High emissions in production but can be recycled rather easily.

b) Embodied Energy:Steel – Very highConcrete – LowTimber – ModerateGlass – Very Low

c) Recyclability:Steel – Melted and reshaped with nearly no loss, saving iron ore, coal and limestone by being recycled.Timber – Carefully stripped and de-nailed, then resized to fit the next job, saves on energy with only a minimal loss of timber if possible.Concrete – Can be crushed and used as gravel for a road or aggregate for new concrete if it is clean.Glass – Crushed and melted, then reshaped, very little loss.

7: Economical Implications of decisions.

Since the concrete base had already been placed well before construction for the reception centre started, the decision to make it had been made very pre-emptively. The value of adding this building had to outweigh the cost of building it, so having a reception centre for the Theology building was clearly a necessity in Melbourne University’s point of view. Being a prized university, the budget for this project would be reasonably high, so that it wouldn’t be a rough job. The way glass blocks have been used outside tells us that the look of the place was of great importance and money was there to spend. Also, the structure of the actual building is very basic and the walls are mostly glass, which is very cheap, but also very bad insulation. This building was designed as more of a transition room rather than a major part of the building.
