FEM-Based Seismic Performance Evaluation of Underground Water Storage Tanks in All Zones

Abstract

Underground liquid storage tank primarily used for water and sewage treatment plants and other industrial wastes. Normally, they are constructed of reinforced concrete in the form of rectangular or circular configurations. The behaviour of liquid storage underground tank during earthquakes is more important than the economic values of the tanks and their contents. A good understanding of the seismic behaviour of these structures is necessary in order to meet safety objectives while containing construction and maintenance costs. In this paper Underground water tank with seismic load in different zones is used to analyze the typical behaviour caused by seismic load. The finite element method (FEM) is selected as the examination method for the underground water tank. The model is performed by ETABS software.
