摘要
Abstract
A reinforced concrete core wall structure is located in 7 seismic intensity area.There are 51 floors on the ground.The building height is 228 meters.In this paper,in order to study the seismic performance of the structure under rare intensity of 7 degree earthquakes,NosaCAD and Perform-3D were used to perform elasto-plastic time history analysis.The results indicate that under rare earthquakes,the yielding hinges firstly occur on some coupling beams,and then some frame columns yield.Finally few concrete of shear wall crushed at the bottom.The maximum inter story drift of the structure can meet the requirement of Chinese code.The order and distribution are reasonable,and the process can dissipate the seismic energy on some degree.The structure satisfies the code requirements of no collapse under rare earthquakes.The calculation results,such as the global response,weak layer and damage condition obtained by the two softwares show an agreement to a certain degree.It is suggested that the envelope value of multi-software analysis can be used to ensure the safety of such complex structure in practical projects.关键词
