Nonlinear Finite Element Analysis of the Composite Structures in Sewage Facilities in consideration of Dynamic Interaction

Abstract

Designers currently evaluate the seismic performance of civil engineering structures in sewage facilities by the seismic coefficient method. However, dynamic interaction between the structure and the ground should be properly considered for the sewage facilities at the soft ground. This study investigated the seismic behavior of it using the nonlinear finite element analysis in consideration of dynamic interaction. Appropriate seismic performance evaluation technique for civil engineering structures in sewage facilities was proposed.
