I'm removing a load bearing wall and the structural engineer recommended a W8x15 steel I-beam. It would save me a lot of effort if I could use a 6" beam instead. So I'm trying to calculate the deflection of the W8x15 beam and then find a W6x?? beam with similar deflection.
I've found the specs for various wide flange beams here, but I can't find a max deflection equation that uses the elastic section modulus provided in the specs.
So, can someone point me in the right direction?
