Abstract
By revoking the effect of vertical component in the analysis of different response quantities of LST may differ from the true response of structure during a seismic event. This paper aims to study the effect of the vertical component of an earthquake on various response quantities, namely tank wall displacement, surcharge at the free surface of the water, overturning moment, and base shear. The study is compiled with the help of nonlinear time history analysis in an explicit finite element module on ABAQUS platform. For illustration, a 10-m long-rectangular liquid storage tank has been modeled by using a solid element with fluid medium modified by the arbitrary Lagrangian and Eulerian (ALE). Investigation for response is done first with bidirectional and then with the vertical component is considered. Some notable conclusions of the study include vertical component alone, which increases the responses to an order of about 30%.
