ASCE 7 Cl. 12.4.2 & 12.5.4
(OP)
I am designing a steel structure in Seismic Design category E using Equivalent Lateral Force procedure. As per Cl. 12.5.4, I should consider 100% seismic load in one direction + 30% seismic load in perpendicular direction.
As per Eq. 12.4.1/12.4.2, I should also consider Ev+-Eh.
Should I apply 30% Ev while combining it with Eh, i.e. 100%Ehx + 30% Ehz + 30% Ev? Or should I consider full effect of vertical seismic load, i.e. 100%Ehx + 30% Ehz + 100% Ev?

When you have a moment, could you pleae look into the code and let me know your views.
