（中国联合工程公司，杭州 310006）[摘要] 采用ABAQUS有限元分析软件分别对来福士塔楼一悬挂部分顶部初始节点和改进节点建立三维力学模型，对其进行了弹性分析和弹塑性极限静力分析。计算结果表明，两种节点均满足弹性要求，改进节点中竖向加劲板仅对钢管混凝土柱外钢管和横向加劲板应力有一定影响，未影响节点极限承载能力。[关键词] ABAQUS; 钢节点; 静力分析; 弹塑性极限分析中图分类号：TU973 文献标识码：A 文章编号：1002-848X(2013)S2-0487-06Finite element statical analysis of steel structure joints based on ABAQUSLi Ying, Huang Zikuang, Li Jianhong, Xie Yanhua Zhang Jianbo Zhou Nan(China United Engineering Corporation, Hangzhou 310006, China)Abstract: The three-dimensional mechanical models of initial joint and improved joint of suspension parts of Hangzhou Raffles Tower 1 were established based on ABAQUS in this article. The elastic and elastic-plastic limit analysis were carried out. The calculation results indicate that two joints can meet elastic demand and vertical stiffening plate of improved joint merely affects steel pipe of concrete-filled steel tubular column and horizontal stiffening plates but excluding ultimate bearing capacity.Keywords: ABAQUS; steel joint; statical analysis; elastic-plastic limit analysis
