摘要
为研究梁柱弱轴连接翼缘削弱型节点的抗震性能,设计了4个翼缘削弱型节点试件和一个普通节点试件,利用有限元软件ABAQUS进行了低周反复荷载作用下的有限元分析,研究了不同削弱深度对翼缘削弱型节点破坏形态、滞回性能、延性性能、承载力的影响。结果表明:翼缘削弱型节点是一种较为理想的延性节点;削弱参数设置合理的翼缘削弱型节点具有较强的延性性能;梁翼缘削弱对试件承载力的影响不能完全忽略。
In order to study the seismic behavior of reduced beam section of beam-to-column web connection of steel frame, four reduced beam section connection specimens and a normal connection specimen were designed. The finite element analy- sis was made using ABAQUS software under cyclic loading, and the influences of dif- ferent reducing depth on failure mode, hysteretic behavior, ductility performance and bearing capacity of reduced beam section connection were studied. The results show that the reduced beam section is an ideal ductile connection;The reduced beam sec- tion connections with reasonable reduced ance. The effect of reduced beam section on parameters have better ductility perform- the bearing capacity can not be neglected.
