（中國聯(lián)合工程公司，杭州 310006）[摘要] 采用ABAQUS有限元分析軟件分別對來福士塔樓一懸掛部分頂部初始節(jié)點和改進節(jié)點建立三維力學模型，對其進行了彈性分析和彈塑性極限靜力分析。計算結果表明，兩種節(jié)點均滿足彈性要求，改進節(jié)點中豎向加勁板僅對鋼管混凝土柱外鋼管和橫向加勁板應力有一定影響，未影響節(jié)點極限承載能力。[關鍵詞] ABAQUS; 鋼節(jié)點; 靜力分析; 彈塑性極限分析中圖分類號：TU973 文獻標識碼：A 文章編號：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
