رد: etabs p-delta combinations?

the global effect to p delta analysis is mainly meant for seismic,for p delta analysis in etabs as it provides only one load combination,so based on the load combinations as per the utilized code pick the biggest factor assigned to gravity loads in the lateral load combinations and insert as load combination in Etabs, for example 1.2D+0.5L+1.0E in P delta load combination in etabs insert 1.2D+0.50L and bear in mind Etabs capture only the global effect of p delta on the entire structure which affect the drift and stability of the structure but for element design to study the local bukling this is not considered by etabs and other procudeours should be followed
