[摘要]成都环球贸易广场办公塔楼建筑高度为280m,属于超B级高度超限高层建筑,采用框架-核心筒结构体系,不设加强层。塔楼抗震性能目标为C级,采用性能化设计方法,并对结构的斜柱受力、楼板缺失、楼板舒适度做了专项分析;采用LS-DYNA软件对结构进行了大震作用下的非线性动力时程分析。结果表明,小震作用下结构主要抗侧力构件处于弹性工作状态;大震作用下框架体系基本完好,筒体剪力墙出现轻微程度损伤;结构变形满足规范要求,结构体系合理可行。

Abstract:The office tower of Chengdu International Commercial Centre is a 280m tall  building with frame-core wall structural system. It is a super class B level height out\|of\|code concrete building without strengthening layer. The seismic performance-based design target is grade C. The performance-based design method was adopted, and the special analyses of the structural inclined column stress, floor slab loss and floor comfort were made. LS-DYNA software was adopted to analyze the nonlinear dynamic time-history under rare earthquake. The results showed that the main structural components to resist lateral force under frequent earthquake is in elastic working state, the framework system can remain basic integrity under rare earthquake, slight injures appear inside core shear wall; structural deformation can reach the code requirement. The structural system is reasonable and feasible.

Keywords:super class B level height; frame-core wall structural system; steel concrete structure; performance-based design
