Effect of Soil Conditions on the Seismic Response of Spatial Structure

Abstract:

This paper is to study the seismic response of spatial structure incorporating the soil structure interaction (SSI). The SSI model for the long-span spatial structure with supporting substructure is proposed and the relevant soil parameters according to the IBC code are presented. A procedure for calculating the total damping ratios for one DOF system is used in the seismic analysis of spatial structure including SSI. The displacement and the axial force in the member under different soil conditions are compared and some important conclusions are drawn.
