摘要
采用有限元软件ANSYS对T型纵向板管连接的方管节点进行了弹塑性大挠度分析,研究了此种节点在往复荷载作用下的滞回性能,通过分析节点的滞回曲线、骨架曲线、滞回环面积曲线和能量耗散系数曲线,得出了纵向板管节点的耗能能力随各参数的变化规律。
Hysteretic behavior of the longitudinal plate to SHS T-type joints under cyclic loads was studied by finite element analysis software ANSYS involved in large deflection elastic-plastic range.Analysis of the hysteretic curves,skeleton curves,the area of hysteretic loop and the energy dissipation factor curves were carried out to obtain the variation regularity of the cyclic performance of joints with parameters of the longitudinal plate-to SHS joints.
