Residential Piled Footing - Raft (Australian)

[BasementCarpark]

Hi,
AS2870 has this requirement for re-entrant corners of raft slab. Do I need to follow this when my raft slab is on piers, which is designed as fully suspended system? I believe this clause is for slab-on-ground only and there is nothing wrong if I don't arrange my piled footing this way since it is designed as suspended, but I am not sure if I violate the code.

If it is pile supported, I don't think you would call it a raft. So, I don't think that Figure would apply.

Thanks.
That's true. I have seen engineers here still call it that way though. That's why I am asking. Everything else including details remain the same except having bored piers under and more reo in slab /beam.

Agree with Hokie, you would move from as2870 to as3600.

Depends where your piles are located relative to the corners, you may end up needing beams to pickup any cantilever which will end up very similar to those figures anyway?
