[摘要] 近年來(lái)大跨空間結(jié)構(gòu)在國(guó)內(nèi)發(fā)展迅猛，同時(shí)發(fā)展起來(lái)各種新型的連接節(jié)點(diǎn)。本文以深圳市當(dāng)代藝術(shù)館與城市規(guī)劃展覽館項(xiàng)目為背景設(shè)計(jì)出符合建筑效果的幾何形狀新穎的節(jié)點(diǎn)。并對(duì)典型節(jié)點(diǎn)建立ABAQUS有限元數(shù)值模型，分析了節(jié)點(diǎn)的受力性能和破壞機(jī)理。結(jié)果發(fā)現(xiàn)考慮大變形的彈塑性有限元分析可以較好地模擬節(jié)點(diǎn)的受力性能，最不利工況下節(jié)點(diǎn)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.
Keywords: complex spatial joints; large-span spatial structure; nonlinear; finite element analysis
