Abstract:Jiantao Plaza is a complicated high-rise connected structure. Both tower buildings adopt frame-corewall system. The top two floors are connected by 72m-span connector steel truss, and the connection between tower and connector is rigid. According to the out-of-code conditions of the project, the objective and method of performance-based seismic design were put forward. The overall calculation under frequent and fortification earthquakes and elastic-plastic analysis under rare earthquakes were carried out. The analysis results show that the performance-based seismic design objective proposed for this project is reasonable and the structural safety can be guaranteed.
Keywords:complicated high-rise building; connected structure; seismic performance; elastoplastic time-history analysis
