摘要
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。
The special-shaped steel grid structure roof of annex for Suzhou Taiping Finance Tower integrates with the tower exterior wall as a whole to present a soft-silk-like continuous curve shape. Steel grid structure supporting system is composed of sliding bearings on the tower,4 dendriform columns raised from basement roof,and V-shaped columns on top of annex roof,and the spatial arrangement is complex. The structural layout and related bearing design were introduced.The dynamic characteristics and the stability of the structure were analyzed. Seismic performance analysis on the key structural members such as dendriform columns was carried out. The finite element analysis was conducted on the key joints. Analysis results indicate that the relevant joint construction can satisfy the requirements of structural safety.
