摘要
本文结合海泰SOHO大厦工程抗震设计的实例,对抗震设防烈度为7度区内的全钢结构框架-支撑结构体系的抗震设计方法进行了简要的阐述,重点就结构高度、平面形状、高宽比等问题进行了探讨。采用SATWE及ETABS(美国)计算软件对结构抗震进行了静力分析及弹性动力时程分析的对比,利用PUSH-OVER方法验算了结构在罕遇地震中破坏的过程,可供同类工程设计参考。
Steel frame-brace structural system has been adopted in the HaiTai Tower,which is a high-rise building out of normal range of Chinese code. This paper discuss the main features of the building in earthquake resistance, such as shape of typical plan and the overall aspect ratio to the top. Seismic linear analysis and time history analysis are used to evaluate the structural behavior excited by earthquakes by two suitable softwares. The experience from the design of this building can be used for reference for similar buildings.
