吴江农村商业银行钢结构设计

Steel structural design of Wujiang Rural Commercial Bank

吴江农村商业银行大楼为框架-核心筒结构,结构高度148.8m;裙房3层高的大跨度钢结构由树形柱支承。结构存在扭转不规则、楼板不连续、尺寸突变等超限情况。根据项目特点对结构进行了时程分析、罕遇地震下的Pushover分析、钢结构屈曲、沉降不均匀等分析,并采用ABAQUS软件对结构的关键节点进行了有限元分析,分析结果表明结构安全合理。同时提出了相应的抗震加强措施。

Wujiang Rural Commercial Bank is a building with height of 148.8 meters and adopts frame-corewall structural system. Large-span steel structure with three floors height of the podium is supported by tree-shaped columns. There are out-of-code conditions of torsion irregularity, slab discontinuity and size mutation in the structure. Time-history analysis, Pushover analysis under rare earthquake, buckling analysis of steel structure and uneven settlement analysis were conducted according to the characteristics of the project, and ABAQUS software was used to conduct finite element analysis on key joints of the structure. The results show that the structure is safe and reasonable. Some corresponding seismic strengthening measures were proposed as well.
