［摘要］对采用不同厚度节点板的750kV格构式变电构架格构柱KT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倍设计荷载作用下的受力及变形情况。结果表明，节点板厚度减小后，设计荷载作用下其仍处于弹性工作状态，1.5倍设计荷载作用下其仍然安全，可为节点板设计提供参考依据。

Abstract: Full-scale tests and relevant finite element simulation analysis were conducted on lattice column gusset-plates with different thickness of a 750kV lattice substation frame to study the stress and deformation behavior under the design load and 1.5 times of the design load.Results reveal that after the reduction of the gusset-plate thickness, the column is still in elastic working state under the design load and keeps in safety under 1.5 times of the design load.The study provides reference for gusset-plate design.

Keywords: 750kV lattice substation frame; gusset-plate; full-scale test; simulation analysis
