Notes about ETABS Default combinations according to ASCE code

Loading

One can notice that ETABS default combination including seismic load (E) is not completely match with basic load combinations at ASCE SEC.2.3.2 (1.2DL+1E +L +0.2S) & (0.9DL+E ). This is because ETABS create combinations mentioned at ASCE SEC.12.4.2.3 which include (vertical seismic load effect 0.2SDS) in addition to (horizontal seismic…

P-delta Analysis

Loading

P-delta is a geometric non-linear effect that occurs in structures that are subjected to compressive loads and lateral displacement. Under the action of compressive loads and lateral displacement, tall slender structures will experience additional stresses and deformations due to the change of position of the structure. First-order structural analysis will…
