［摘要］針對750kV格構(gòu)式變電構(gòu)架K形節(jié)點進行了足尺試驗及有限元仿真分析，考察了其在設(shè)計荷載和15倍設(shè)計荷載下的受力變形情況及極限承載力。結(jié)果表明，設(shè)計荷載下750kV格構(gòu)式變電構(gòu)架K形節(jié)點仍處于彈性工作狀態(tài)；15倍設(shè)計荷載下，該節(jié)點仍然安全。

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
