In a steel framed house, the loading path of the house structure is used to determine the design requirement. The roof loads, wind loads, wall loads and floor loads will be transferred all the way down to the ground floor. A steel framed house would normally be built on a reinforced concrete ground floor slab. The ground floor wall panels would then be fastened and held down to the ground floor slab. The second storey floor bearers would then sit on the top of load bearing walls. These bearers would connect and carry the floor joists. The floor joists would, in turn, carry the floor boards and the wall panels above. The roof trusses would then sit on the wall panels to carry the roof system and roof loads. The sizes and spacing of the structural members would depend on the design loads. Generally, Elsek Steel Construction recommends the following:
Connections for steel framing can consist of rivet, self-drilling screws, bolts and anchors. Welding is usually not required and mechanical fasteners would suffice in most cases.
