摘　　要：针对750k V格构式变电构架K形节点进行了足尺试验及有限元仿真分析,考察了其在设计荷载和1.5倍设计荷载下的受力变形情况及极限承载力。结果表明,设计荷载下750k V格构式变电构架K形节点仍处于弹性工作状态;1.5倍设计荷载下,该节点仍然安全。The full-scale test and finite element simulation analysis on K-shaped joint of 750 k V lattice substation frame were carried out to investigate the deformation and ultimate bearing capacity under the design load and 1. 5 times of the design load. The results show that the K-shaped joint is still in elastic state under the design load,and the joint is safe under 1. 5times of the design load.
