Constructing Environments Assignment 2: Full Size Option 1: In situ
Site: Williams Cove, 121 Kororit Creek Road, Williamstown Construction Company: Stonehenge Introduction: These are luxury houses on a 173 m2 piece of land with a view onto the lake, open living areas and balconies. It is three stories high consisting of 3 bedrooms and a double garage. Materials • Bricks: Strong in compression • Square hollow system (SHS) Structural steel • Timber: is ductile and not as brittle, low embodied energy, as it is sourced locally so is cost effective as well. Needs to be kept away from moisture and water. • Reinforced Concrete: hard durable flooring system. (Compressive strength of 32MPa) • Bolts: some 4.6 (460mPa) commercial bolts and some 8.8 High Strength • Mortar: mix with limestone, cement and water. • Nails
Structural Features Footings: Strip footings are used which run around the outside of the house with dimensions typically 200 x 300. The concrete slab sits on top of the footings. Slab: takes the live load of occupants and transfers loads from walls to the footings Brick wall for garage is double skin load bearing wall.
Timber Stud Frame, Load bearing wall. -‐Temporary Bracing is attached until second floor is erected and will provide lateral stability. -‐Noggins to prevent buckling in vertical studs. Unsure of strength as didn’t get to see up close. Structural Steel: Works together with the timber in the walls , since there is 3 stories high and require more strength. This Keeps the walls the same size around the house and not take up more floor space. Detailing • Currently only a brick wall. • Downpipes for drainage of stormwater • Windows • Plants • Weep holes in bricks to allow water to get out and give ventilation • Cladding to be attached to timber stud walls later. Connections • Footings and slab cast together and are interconnected (poured on top of each other) • Timber and steel framing for walls are bolted to the concrete slab. • Timber studs, noggins, bottom plates and top plates are attached with a nail gun. • Bricks are attached by mortar. • The structural steel is only a pin connection, although the connection to the slab is bolted it provides some moment capacity. It is only when it is tied into the timber stud frame that it becomes a rigid connection. (can take lateral loads).
•
Connection plates to form a truss and for joists to beam connection.
• •
This is the opening of the living room with big glass windows and sliding doors. The span of the opening is too long to use timber as it is hard to get structural timber more than 6m long. Instead steel is used as it doesn’t deflect as much and can be prefabricated to longer lengths.
•
F17 Structural timber has been placed inside the I Beam (Universal Beam) to allow connections to trusses as joists.
•
Ceiling joists will support the level 2 floor.
•
To the left, there is a load bearing masonry brick wall. There is a lintel running across the opening where there is going to be a double garage.
•
There will be bricks placed on top of it, which the lintel will support.
•
The lintel transfers the loads along it to the brick masonry walls on either side.
