A single-storey brick veneer house (single layer of brick on a timber frame) has a front corner lounge-room with a floorplan measuring 4.0 m by 3.8 m. The ceiling is 3.0 m high. The building fabric of the two exterior walls comprises a 12 mm thick layer of plaster, a 100 mm air gap and the exterior house bricks (110 mm thick). One of these walls has a window measuring 2.7 m wide by 1.35 m high, featuring a 3-mm thick glass pane installed in the mid-1950s. The floor is carpet over 19 mm thick pine floorboards, and the house is on stumps with a ventilated air gap between the ground and the floorboards. The ceiling is 12 mm plasterboard covered with a 50 mm thick layer of loose fill insulation in the roof cavity. This house is located in suburban Melbourne.
Based on your own research into pricing for retrofitting double glazing, modern insulating single-glazing, adding ceiling or under-floor insulation, or other measures, what would be the most cost-effective strategy for improving the heat retention of the room? Show calculated results for at least three alternatives.

Using the formulas and codes provided by ACI 318
1. Design a square interior column footing for a 15-in. square tied
interior column that supports a dead load of 160 kips and live load
of 180 kips. The column is reinforced with eight # 8 bars, also,
the base of the footing is 6 ft below the grade line, the soil
weight is 100 lb/ft3, the concrete weight is 150 lb/ft3, f’c =
4,000 psi, fy = 60,000 psi and qa = 4 kip/ft2.
2. What is the importance of providing enough thickness for the footing of a structure.

Discuss:
1. Experimental vs. theoretical values for the horizontal
reactions.
2. A UDL is the most significant contribution to the horizontal
reaction. This is mainly
because of the weight of the road deck of a bridge.
3. What is the relationship between the rise (r) and the horizontal
reaction?
4. Discuss: a three-pinned arch is ideal for sites where the
abutments are likely to
settle. Obviously, the shape of the arch has no bearing on the
horizontal reaction
(given the same span and rise)
