摘要

针对特高压输电塔结构空间KK型钢管—板节点进行非线性有限元分析，考查了节点的破坏模式和极限承载力。重点分析了腹杆加载比例、几何参数和主管应力比等对空间KK型钢管—板节点极限承载力的影响。结果表明，腹杆加载比例为正时，节点极限承载力随其增大而显著降低；腹杆加载比例为负时，其对节点极限承载力的影响不大；主管应力比对节点极限承载力的影响随腹杆加载比例的变化而对节点的受力性能形成复合影响效应。在此基础上，通过对数值结果的回归分析，并综合考虑各种因素对节点极限承载力的影响，提出了该类节点的极限承载力计算公式。

Abstract

A nonlinear finite elements analysis was carried out to investigate the failure modes and the ultimate strength of gusset plate to CHS KKjoints. The effects of web loading proportion

geometric parameters and axial stress in chord on the ultimate strength were considered. It was found that the ultimate strength of gusset plate to CHS KKjoints was greatly decreased with the increase of web loading proportion when the proportion value was positive; however

the web loading proportion had less effect on the ultimate strength when the proportion value was negative. And with the varying of web loading proportion

the effect of the axial stress in chord on the ultimate strength of KKjoints had a complex effect on the joint mechanic behavior. Based on the regression analysis

a formula was proposed for predicting the ultimate strength of gusset plate to CHS KKjoints.
