摘　　要： 钢管混凝土巨型斜交网格体系作为筒中筒结构的外筒,使筒体结构具有很大的抗侧刚度,其抗震性能的研究是迫切的需要.本文根据基于性能的抗震设计方法,采用PERFORM-3D软件的纤维模型对超高层钢管混凝土巨型斜交网格筒中筒结构进行了强震作用下的非线性分析,比较了结构在7、8、9度地震作用下的反应。结果表明该结构体系适用于较高抗震设防地区,为该结构体系的应用提供了依据。 In this paper, a huge oblique lattice structure with concrete filled steel tube is used as the outer tube of tube-in-tube structure. It is urgent to research the Seismic performance of this structure system, which has large lateral stiffness. According to the performance-based seismic design method, the nonlinear analysis of a super highrise huge oblique lattice structure with concrete filled steel tube under severe earthquake is conducted by using fiber model of PERFORM - 3 D procedure. The structural responses under seismic actions with intensity Ⅶ,Ⅷ or Ⅸ are compared with each other. It is shown that the structure system is feasible to be applied to highly fortified seismic regions.
