Research on Elastic-Plastic Time-History Analysis of a Tall Building Under Rare Earthquakes

Abstract

This paper takes a tall building as background, which the intensity of the resistance is 6. The building has a structure height of 183m. The RC frame-core wall structure system was used for this building. We focus on the research of the whole structure and members under e strong earthquake, the evolution of the plastic of the structure under strong earthquakes. Midas software was adopted to analyze elastic-plastic time-history and identify the yielding mechanism, weak link and possible damage type. The whole structure seismic performance has been evaluated which has a guide meaning for transfinite tall buildings in the future.
