摘　　要：铸钢节点以其良好的受力性能及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。本文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,得出了一些有益的结论。With favorable high-blooded capability and strong adaptation, cast-steel joints has been applied in many large span-space structures, but presently there is not a well-rounded design criterion in China which can be used. In this case, model test is necessary to the typical complex joints. This paper introduces the experimental research on some main joints in the Center of Exhibition and sport of Nantong, and some useful conclusions are obtained by comparison with the results of nonlinear analysis.
