Hi every body,

I work with CAESAR II V4.5 .
I want to know how are you considering eartquake occasional load cases in static analysis?

Assume Ux, Uy and Uz as static uniform loads due to earthquake, each of them along each axis and y-axis is vertically.

I consider occasional load cases, due to earthquake, in two ways, simultaneously:
first along each axis: W+P+T±Ux, W+P+T±Uy and W+P+T±Uz.
and second in two vertical planes: W+P+T±Uy±Ux and W+P+T±Uy±Uz.

Please, tell me which of them is prefered and why, or there is some other ways that I don't know, or I could go on as I described before!?

Looking forward your comments.

With High Pleasures.
Bye.

M. Sami
