Simplified Elastic Plastic Response Analysis Method of Piping

Abstract

Under extreme seismic excitation, plastic deformation occurs in piping system. It is considered that the large damping effect causes with energy dissipation by the plastic deformation. In this study, a simplified method to calculate the damping effect and maximum seismic response of piping with plastic deformation was examined. The maximum response by this method resulted in appropriate simulations of the excitation tests of the piping models.
