摘　　要：某国际中心是一座94 m高的一类高层塔式办公楼,混凝土框架-核心筒结构。除核心筒长向偏置外,结构平面布置较为对称、规则;但东侧门厅一~四层挑空,形成8根18 m高穿层柱。门厅挑空造成结构平面、竖向有多项不规则,属超限高层结构。采用SATWE、PMSAP程序进行小震反应谱弹性计算对比分析,并采取相应的抗震构造加强措施,基本保证了结构具有较好的抗震性能,结构设计满足现行规范各项抗震设防设计要求。A certain international center is a high-rise tower-type office building with 94 m high,concrete frame-core tube structure.Except for the long bias of the core tube,the layout of the structure is more symmetrical and regular,but the eastern entrance hall is of void structure from the first to forth floor,which forms eight 18-m-high through-storey columns. The void-structure entrance hall results in a number of irregular plane and vertical structure,which belongs to the overrun high-rise structure. The SATWE and PMSAP programs are used to calculate,compare and analyze the elasticity of small earthquake response spectrum,and take corresponding measures to strengthen the anti-seismic structure,which basically ensures that the structure has better anti-seismic performance. This structural design meets all the anti-seismic design requirements of the existing standards.
