沈阳市府恒隆广场塔楼一为东北地区最高的建筑之一,采用SAP2000软件对其皇冠结构及二次结构进行静力分析,采用ABAQUS软件对擦窗机支架与皇冠外弦杆受力最大的节点进行有限元分析。分析结果表明,皇冠结构及二次结构构件的应力比、变形及整体稳定性均满足相应规范要求;根据强节点弱构件的原则,整体计算结果也满足强节点设计要求。通过精确建模及详细的计算分析可知,结构体系的合理布置是保证整个皇冠结构顺利竣工的关键,本工程的钢结构施工达到预期,并取得了良好的经济效益。
Shenyang City Hall 66, one of the tallest buildings in Northeast China, uses the SAP2000 software to perform static analysis on its crown structure and secondary structure. ABAQUS software is used to test the node with the highest stress on the gondola bracket and crown chord Finite element analysis. The analysis results show that the stress ratio, deformation and overall stability of the crown structure and the secondary structural members meet the corresponding specifications. According to the principle of strong members and weak members, the overall calculation results also meet the requirements of strong node design. Through accurate modeling and detailed calculation and analysis, we can see that the rational arrangement of the structural system is the key to ensure the smooth completion of the entire crown structure. The steel structure construction of this project has achieved the expectation and achieved good economic benefits.
