［摘要］针对750kV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750kV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。

Abstract:The fullscale test and finite element simulation analysis  on Kshaped joint of 750kV 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5 times of the design load.

Keywords:750kV lattice substation frame; Kshaped joint; fullscale test; simulation analysis
