[摘要] 近年来大跨空间结构在国内发展迅猛，同时发展起来各种新型的连接节点。本文以深圳市当代艺术馆与城市规划展览馆项目为背景设计出符合建筑效果的几何形状新颖的节点。并对典型节点建立ABAQUS有限元数值模型，分析了节点的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较好地模拟节点的受力性能，最不利工况下节点是安全的。

Abstract: The large-span spatial structure has been developed rapidly in recent years, and new types of joints have been developed at the same time. Novel types ofjoints have been created to satisfy architecture are effect based on the project of the museum of contemporary art and planning exhibition in Shenzhen. Then finite element modes for new joints are established with the software ABAQUS. Results indicate that the elastic-plastic nonlinear analysis considering large deformations can simulate the bearing behavior of the joint satisfactorily and the joints are safe under the most load case.
