Nonlinear Seismic Response Analysis of Parallel Base-Isolated System

Abstract:

Based on the bilinear hysteretic model, the elastic-plastic time history analysis of single mass point for parallel base isolation system is carried out. The approximate treatment method of the inflexion point is introduced and the formula of each energy consumption for parallel base-isolated structure is given. Through an engineering example, the time history curve of each energy dissipation for parallel base-isolated system is drawn, and the isolation effect is given.
