An Earthquake plays an important role in studying the behavior of structure, since they were used for living and storing purpose. Earthquake shaking depend on the intensity of vibration, the nature of rock, the surface soil type and depth of soil above the bed rock. As we have seen in past many elevated structure were collapsed or damaged during the seismic activity. When there is horizontal ground motion, the tank wall and liquid are subjected to horizontal acceleration. So, in Staad.Pro, we
