For typical conventional slab formwork, you would allow for an additional 25% to the centre leg of a triple frame setup with a 2 span bearer (eg. located under slab beams) to account for the increased internal support load due to a 2 span beam. Typically under flat slabs, you would design bearers based on a min 3 span bearer which results in an additional 10% to the 1st internal support. 

Thank you Evan. This exactly matches with what I have been doing.

And this was my question too. I do add 25% when using so called "Area method" of leg load estimation because of that double bearers can rest on 3 supports in the worst case but I haven't seen it in the norms. Where cen I find it? Thank you in advance.

Yeah, this was my question, so when? )
