in the static analysis, I have always combined the PSV reaction force with the sustained case directly (W+P+F) and have checked it as an occasional case. recently I have recieved a recommandation from the client to change it as per what it is normally done for a static seismic or wind load case:
L1 W+P+T+F
L2 W+P+T
L3 W+P
L4 L1-L2 (ALGEBRIC)
L5 L3+L4 (SCALAR)
my question is; is it not really overkill for a PSV reaction force to make its load case as mentioned above? if not, why should we not make such load case for spring hanger load? (both are constant point force on the system)
