Seismic analysis of spherical tanks including fluid-structure-soil interaction
Seismic analysis of spherical tanks including fluid-structure-soil interaction
The accurate and efficient, from a practical point of view, analysis of spherical tanks is the primary motivation for this work. The proposed methodology implements: (a) the Boundary Element Method (BEM) for the simulation of the soil-structure interaction, (b) a discrete 2-DOF mechanical system for the approximate computation of the impedances of a massive, rigid, ring foundation, a usual feature of a spherical tank, and (c) a FEM simulation of the structure and fluid regions. The above modules are coupled via the pre-and post-processing capabilities of the widely used general purpose program ANSYS. The entire analysis is performed directly in time domain assuming linear elastic structure and soil region

Abstract
The accurate and efficient, from a practical point of view, analysis of spherical tanks is the primary motivation for this work. The proposed methodology implements: (a) the Boundary Element Method (BEM) for the simulation of the soil-structure interaction, (b) a discrete 2-DOF mechanical system for the approximate computation of the impedances of a massive, rigid, ring foundation, a usual feature of a spherical tank, and (c) a FEM simulation of the structure and fluid regions. The above modules are coupled via the pre-and post-processing capabilities of the widely used general purpose program ANSYS. The entire analysis is performed directly in time domain assuming linear elastic structure and soil region
