Australian Standards Combination Loadcase Factor For Pad Footings
Australian Standards Combination Loadcase Factor For Pad Footings
(OP)
Is there anywhere besides AS2870 that gives recommendations for load combinations to check against (soil) bearing failure.
I know the British Standards uses unfactored load case combinations but there doesn't seem to be any advise in the Aussie codes apart from the residential slabs and footing code.

By the way, there is an AS/NZS code forum under Engineering codes Standards and Certifications category.

This can be any combination of Permanent Load (Dead Load), Imposed Load (Live Load) and Wind Load. For wind load, a working load must be used which is 1.5 times less than the ultimate wind load (refer AS1170.2:1989).
As for where the load combinations come from. I don't know because AS1170 (latest revision) is written in a limit state format.
AS4678 tried to incorporate a limit state approach to geotechnical parameters however there was some criticism because the material is not as well known as other building materials that structural engineers deal with so it is difficult to apply and material strength reduction factor (φ).
