hi
is it possible to design water retaining structures in staad pro ,if possible then how to design it plz explian mthanks in advance.
Sure, you can analyze water retaining structures in STAAD.pro. I expect it's a fairly common use of the program. Our Help - Contents - Tutorial Problem 3 is a concrete flat plate structure that's not quite the same as water retaining structure, but a pretty good place to start learning how to use shell elements.
