Abstract

Abstract

Based on ASCE-4-98, the 3D FEM model of large storage tank was established. The effect of liquid sloshing was simulated by the mass-spring model. The seismic analysis was processed by ANSYS software. The FEM calculated frequency of liquid sloshing was identical to the formula result of ASCE-4-98, shown that the 3D FEM model is reasonable and usable. It is a simple and suitable engineering method, from which, the stress distribution of the storage tank can be obtained directly from the 3D FEM model.
