摘要
某超高层主体结构高285m,为带伸臂桁架的型钢混凝土框架-钢筋混凝土核心筒结构。结构角部区域采用悬挑桁架以悬挂或上托多个楼层,悬挑尺寸约6m。对悬挑桁架的腹杆及相邻内跨腹杆布置形式、杆件截面形式以及竖向地震作用加速度放大系数进行了分析和探讨,相关结论可供同类工程设计参考。
The height of the super high-rise building is 285 m. SRC frame-RC core wall system with outrigger is adopted.Cantilever truss,of which maximum cantilever length reaches to 6 m,is applied in the angular region to hang or undertake several stories. The shapes and sections of truss members was carried out and acceleration amplification factor under vertical seismic action was analyzed. Relevant conclusions can be as references for similar projects.
