摘要
利用通用有限元软件Strand 7分析了佛山世纪莲体育场屋盖钢结构的相贯钢管节点。由于该屋盖的上、下压环节点构造较为特殊,为了保证其安全可靠,对上、下压环节点进行了有限元分析,其中混凝土采用弹塑性的本构关系,钢管采用弹性的本构关系。通过分析得出在最不利组合下混凝土及钢管和节点板的受力情况。最后还分析了节点板与销栓的弹塑性接触问题。
The tubular joints of roof steel structure in Foshan Century Lotus Stadium are analyzed by the finite clement software of Strand 7. Because of the especial connections of the upper and lower compression ring, it is necessary to run a finite element analysis in the tubular joints to ensure the safety of them. The elasto-plastic constitutive relation is used in concrete element. The constitutive relation of steel is elastic. In the worst load combination, the actual stress situations of concrete and tubular joints and gusset are put forward, Finally, contact method is used to analyze the elastoplastic contact behavior between gusset and pin,
