铸钢节点具有较强的适应能力被广泛应用于各种大跨度空间结构中,在目前暂无国家统一设计规范的情况下,对受力复杂的铸钢节点辅以足尺或模型试验是非常必要的。结合南通体育会展中心工程,对部分重要节点进行了试验研究,并与弹塑性非线性有限元分析结果对比,证明工程设计所用的分析理论基本符合铸钢节点的实际工作状况,节点具有足够的安全储备。 Cast steel nodes have strong adaptability is widely used in a variety of large-span space structure, at present there is no national uniform design specifications, the complexity of the steel node with a full-scale or model test is very necessary. Nantong Sports Convention and Exhibition Center project, some of the important nodes were studied and compared with the elastoplastic nonlinear finite element analysis results show that the engineering design used in the analysis of the basic theory of steel nodes in line with the actual working conditions, the node has sufficient safety reserve.
