苏州太平金融大厦裙房屋面异形钢网格结构与塔楼外墙形成一体并呈现出丝绸般柔软的连续曲线造型,钢网格结构支承系统由搁置于塔楼的滑动支座、地下室顶板升起的4根树形柱、裙房屋面上部的V形柱组成,空间布置复杂。介绍结构布置及相关支座设计,分析结构的动力特性及稳定性能,并对树形柱等关键结构构件进行抗震性能分析,对关键节点进行有限元分析。分析结果表明,相关节点构造能满足结构安全性要求。 Suzhou Taiping Financial Building Skirt shaped roof steel mesh structure and the outer wall of the tower is formed and presents a silky soft continuous curve modeling, steel grid structure supported by the system resting on the tower sliding support basement raised 4 Root tree-shaped column, skirting the upper part of the V-shaped column composition, space layout is complicated. The structure layout and related support design are introduced. The dynamic characteristics and stability of the structure are analyzed. The seismic performance of the key structural members such as tree-shaped columns is analyzed, and the critical nodes are analyzed by finite element method. The analysis results show that the related node structure can meet the structural safety requirements.
