Re: Our earthquake code columns are only axial load stone first of all thanks for responding to my question; Well, I think we can't design according to axial load only because of the shear forces created by these earthquake effects, so you considered it as the absence of an earthquake. While defining the loads in programs such as idecad or sta4cad, we also affect the movable and fixed loads such as Q, G and E, as well as wind and earthquake loads. and they don't act as an axial pressure force on the column? I mean, I'm talking only about taking the earthquake load as a combination of loads and affecting it. I will be glad if you answer or help with good work.
