ELASTIC-PLASTIC EARTHQUAKE RESPONSE ANALYSES OF HIGH-RISE BUILDING COMPOSED BY SUPER-STRUCTURE FRAME

Abstract

This paper presents the elastic-plastic earthquake response analytical method using equivalent vibration model for aseismic design of high-rise building composed by super-structure frame. This equivalent vibration model is set up based on the results of rigorous elastic-plastic static analysis. The authors present how to make the equivalent vibration model and decide its skeleton curve. The elastic-plastic earthquake response analytical results of this newly developed model are compared with the results of the rigorous earthquake response analysis. Finally, it is clarified that this proposed model is very adequate and effective to investigate earthquake response characteristics of superstructure frame.
