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 Building is a frame-core tube structure with a height of 148.8m. The 3-storey podium steel podium is supported by a tree-shaped column. Structural irregularities exist torsion, floor discontinuity, size mutations such as overrun situation. According to the characteristics of the project, the structure was analyzed by time-history, Pushover analysis under rare earthquakes, buckling of steel structure and settlement nonuniformity. The finite element analysis of the key nodes of the structure was carried out by ABAQUS software. The results show that the structure is safe and reasonable . At the same time, the corresponding seismic strengthening measures are proposed.
