摘要:天音大厦项目A座和C座塔楼,因立面复杂、造型独特,存在大悬挑和多项结构不规则。根据建筑功能的需要,确定合理的结构形式,采用SATWE、MIDAS Building软件对结构在多遇地震和风荷载作用下进行计算分析,采用SAUSAGE软件对结构在罕遇地震作用下进行计算分析,得到了振型周期、层间位移角、楼板应力、楼盖舒适度、构件挠度、关键构件受力性能等重要的分析结果。结果表明:A座采用悬挑空腹桁架和斜柱转换,C座采用悬挑桁架的结构形式,传力路径明确,结构计算各项指标满足规范要求,结构设计合理、安全、可靠。

Abstract: Tower A and tower C of the Tianyin project, due to the complex fa9ade and unique shape, there are large overhangs and a number of structural irregularities. According to the needs of building functions, a reasonable structural form was determined, SATWE and MIDAS Building software were used to calculate and analyze the structure under frequent earthquakes and wind loads; SAUSAGE software was used to calculate and analyze the structure under rare earthquakes, and important analysis results such as mode shape period, interlayer displacement angle, floor stress, floor cover comfort, component deflection, and stress performance of key components were obtained. The results show that tower A adopts the cantilever vierendeel truss and oblique column conversion, and tower C adopts the structural form of the cantilever truss, the force transmission path is clear, the structural calculation indicators meet the requirements of the specification, and the structural design is safe, reasonable and reliable.
Keywords: out-of-code high-rise building; frame-core wall; hybrid structure; vierendeel truss; steel brace; large overhang; performance-based design
