某双塔高层办公楼结构设计

STRUCTURAL DESIGN OF AN OFFICE BUILDING WITH A TWIN-TOWER HIGH-RISE STRUCTURE

某双塔高层办公楼因受到建筑外型限制,无法设置抗震缝,造成结构不规则。为研究其抗震性能,从结构设计入手,针对结构不规则采取相应加强措施。罕遇地震弹塑性时程分析结果表明,结构具有良好的抗震性能,满足规范要求,为后续类似项目设计提供参考。

Limited to the restrictions of architectural appearance,a twin-tower high-rise building is unable to set seismic joints.Aiming at the structural irregularity,reinforcement measures are proposed and analysis of elas⁃tic-plastic time history under rare earthquakes are carried out to study the seismic performance of the structure.The results show that the structure has good seismic capacity and meet code requirements,providing the reference for similar projects.
