摘要: 杭州智慧大厦的两栋高层建筑分别由四个不同尺寸盒式建筑体块沿高度方向交错叠合形成，有较多内退、外挑及通高空间，并通过连接体连接，造型复杂。结合建筑造型，采用钢管混凝土框架-核心筒结构体系，外挑空间采用悬挑桁架抬柱或吊柱形式。首先对该结构进行超限情况判定，采取相适应的抗震性能目标及超限应对措施。然后通过性能化分析，总结结构的整体受力特性，并通过弹塑性时程分析检验关键构件在大震下的性能。最后，针对关键部位及设计难点，补充连体结构设计、节点分析、楼盖舒适度分析、穿层柱屈曲分析等。分析结果表明，结构具有较好的抗震性能，结构安全可靠。

Abstract: The two high-rise buildings in the Hangzhou Wisdom Building are respectively formed by four box-shapedbuilding blocks of different sizes that are staggered and superimposed along the height direction. There are many interiorfacade setbacks,exterior overhanging and full-height spaces,which are connected by connecting bodies with complexshapes. Combined with the architectural shape,the CFST frame-core wall structural system was adopted,and the exterioroverhanging space adopted the form of cantilevered truss lifting column or hanging column. Firstly,the out-of-code situationof the structure was determined,and the appropriate seismic performance targets and out-of-code countermeasures weretaken. Then,through performance-based analysis,the overall mechanical characteristics of the structure were summarized，and the performance of key components under rare earthquakes was tested through elasto-plastic time-history analysis.Finally,according to the key parts and design difficulties,the design of connected structure,joint analysis,floor comfortanalysis,and buckling analysis of skip-floor columns were supplemented. The analysis results show that the structure hasgood seismic performance,and the structure is safe and reliable.
