[摘要] 采用ABAQUS有限元软件建立深圳当代艺术馆与城市规划展览馆的钢桁架与核心筒墙连接节点以及钢梁与型钢柱连接节点的分析模型，来研究其受力性能和破坏机理。结果发现考虑大变形的弹塑性有限元分析可以很好地模拟节点的受力性能，在最不利工况下节点是安全的。

Abstract: The fuute element modes for joints of steel truss-concrete core wall and joint of steel beam column were established with the software ABAQUS based on the project of the museum of contemporary art and planning exhibition in Shenzhen. Results indicate that the elastic-plastic nonlinear analysis considering large deformations can simulate the bearing behavior of joints satisfactorily and the joints are safe under the most damaging load case.
Keywords: joint of cantilever steel truss and core wall; large-span spatial structure; nonlinear; finite element analysis
