斜柱在退台收进高层结构中的应用及抗震性能分析

Application of Inclined Columns in Retractable High-rise Structures and Seismic Performance Analysis

针对外部轮廓连续退台收进建筑,研究利用斜柱及斜撑组成斜向框架做为承重结构及抗侧力体系,实现结构的层层退台收进;通过考察相似项目的做法,采用不同的力学模型进行对比分析,对斜柱、斜撑,以及与斜柱相连梁的抗震性能进行分析,以达到结构的安全性能目标,为类似建筑的结构设计提供参考。

Aiming at the buildingwith continuous setback and setback of external contour,the diagonal frame composed of diagonal columns and braces is studied as the load-bearing structure and lateral force resisting system to realize the setback and setback of the structure layer by layer;Through investigating the practice of similar projects,different mechanical models are used for comparative analysis,and the seismic performance of diagonal columns,diagonal braces,and beams connected with diagonal columns are analyzed to achieve the safety performance goal of the structure and provide reference for the structural design of similar buildings.
