通过某特高压输电线路塔架结构中典型的单角钢螺栓连接节点的足尺试验,对节点板的受压性能、破坏形式及极限承载力进行了研究。利用有限元程序ANSYS建立合理的有限元模型模拟节点板的受力性能,并与试验结果进行了对比分析。将试验及有限元模拟结果与现行国内外钢结构规范关于节点板受压承载力计算公式的计算值进行了比较,验证了现行规范公式对于该类单角钢连接节点板受压承载能力计算的适用性。 Through the full-scale test of the typical single-angle bolted joints in the tower structure of a UHV transmission line, the compression performance, failure mode and ultimate bearing capacity of the joint plate are studied. The finite element model ANSYS is used to establish a reasonable finite element model to simulate the stress performance of the joint plate, and compared with the experimental results. The experimental and finite element simulation results are compared with those of the current domestic and foreign steel structure codes for calculating compressive bearing capacity of gusset plate. The results show that the current code is valid for the calculation of compressive load carrying capacity Sex.
