Settlement of the tank under seismic condition
Settlement of the tank under seismic condition
(OP)
Dear Sirs,
I'm performing stress analysis for a tank. Civil department sent me an email about settlement of the tank for different conditions. He specified settlement under operating, hydro test and seismic condition. In most documents settlement at operating condition are considered for stress analysis. Now I'm not sure about using settlement of the tank under seismic condition. Is it important to consider this settlement for stress analysis or operating settlement is enough?
