[摘要]武汉华侨城某超高层建筑采用剪力墙结构,结构高度为169-7m。该项目存在高度超限和扭转不规则、凹凸不规则等不规则项目,同时建筑平面外墙转角处存在转角窗。采用抗震性能化设计方法,设定性能目标D级,依据《高层建筑混凝土结构技术规程》(JGJ 3—2010)进行了小震、风荷载作用下的结构分析,并采取等效弹性方法对结构关键构件进行了中、大震下的承载力验算,采用PKPM SAUSAGE程序进行了罕遇地震弹塑性动力时程分析,对结构整体形态和关键构件的塑性开展进行了研究。结果表明,项目各关键构件满足所设定的抗震性能目标,结构具有良好的抗震性能。

Abstract:A super high-rise building of Wuhan Overseas Chinese Town is adopted reinforced concrete shear wall structure with the building height of 169-7m. There are irregular items in the project including super high-rise, torsional irregularity and uneven irregularity. And there are corner windows at the corner of the building exterior wall. The performance-based seismic design method was used with a D-level performance target. According to the Technical specification for concrete structures of tall building(JGJ 3—2010), the structure was analyzed under frequent earthquake and wind load. The capacity of key structural components were checked by equivalent elastic method under fortification and rare earthquakes. The elastic-plastic dynamic time-history analysis was carried out by using PKPK SAUSAGE program to research the overall structural performance and the plasticity development of key components under the rare earthquake. The results show that all the key structural components meet the established seismic performance objectives and the structure has a good seismic performance.
Keywords:super high-rise building; torsional irregularity; uneven irregularity; corner window; performance-based seismic design
