为研究新疆国际会展中心屋面张弦桁架支座铸钢节点的承载性能,对该铸钢节点的1/2缩尺试件进行了加载试验.试验结果表明,在最不利设计工况组合下,节点满足设计的承载能力要求.对节点试件进行弹塑性有限元分析,结果表明有限元分析结果与试验结果吻合良好,验证了有限元数值模型的可靠性.对铸钢节点的承载性能指标和安全储备进行了综合评估,为张弦桁架铸钢节点工程设计提供试验数据和参考.
In order to study the bearing capacity of cast-in-situ chord truss bearing steel castings in Xinjiang International Convention and Exhibition Center, a half-size scale specimen of the cast steel joint was subjected to loading test.The results show that under the most unfavorable design conditions, The results show that the finite element analysis results are in good agreement with the experimental results, and the reliability of the finite element numerical model is verified. The bearing capacity of the steel node and Safety assessment of a comprehensive assessment of the truss steel truss for the engineering design to provide test data and reference.
