［摘要］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。

Abstract:The No.1 tower building of Henglong City Plaza in Shenyang is one of the highest buildings in the Northeast China. SAP2000 software was used to conduct static analysis on the crown structure and its secondary structure, and ABAQUS software was used to conduct finite element analysis of bracket of the window wiping machine and joints of crown′s exterior chords with the largest stress. The analysis results show that the stress ratio, deformation and overall stability of crown structure and its secondary structure meet the corresponding requirements of codes; according to the principle of strong joint and weak component, the overall calculation results also meet the design requirements of strong joint. The precise modeling and detailed calculation and analysis show that the reasonable layout of structural system is the key to ensure the smooth completion of the crown structure, the steel structure construction of the project meet expectations and achieves good economic benefits.

Keywords:crown structure; bracket of the window wiping machine; secondary structure; key joint
