LYONS CONSTRCUTION COMPANY SITE IN GEELONG:

This site is currently constructing warehouses where the concrete cladding is actually a structural support.

IMAGE 6: Columns were a structural requirment throughout the space, therefore this type of construction would not be suitable if a large open span is required.

MAJOR ASSIGNMENT RESEARCH

TALK WITH ENGINEER TOM EVANS AT EARTH TECH GEELONG OFFICE:
Discussed the Scenario of a 40m x 40m warehouse with Tom Evans. He talked about a number of design considerations and suitable structural members for a warehouse of this size constructed with a steel portal frame:
- Think about height/clearance requirements
- Roof material effects the pitch
- Limit the span of columns to around 8 - 9 metres
- Use lapt ‘z’ purlins with a depth of 250mm as they will be most efficient
- Use rod bracing
- If you use the same spacing on all walls then the same girts can be used all over
- Approopriate columns would be around 610UB
- Use broad piers of 1200mm diameter which go about 3m into the ground
- Reinforce the concrete slab with 8N28 bars space evenly around perimeter
- Use pin connections, with bolts going about 1m into the footing
- Rafters around 530UB
- Safety mesh is attached from below using a lift for safety
- Welding: CRW (Continuouse Fillet Weld) is used to fill corners on 90 degrees in a triangle section.
FSBW (Full Strength Butt Weld) is used on flanges
-HE ALSO PROVIDED PHOTOCOPIES OF INFORMATION ON PORTAL STRUCTURES
