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 performance of flange-weakening joints with weak-axis flanges, four flange-weakened joint specimens and one ordinary joint specimen were designed. Finite element analysis (FEM) software ABAQUS The influence of different weakened depth on the failure morphology, hysteretic behavior, ductility and bearing capacity of flange-weakening joints was analyzed and studied. The results show that the flange-weakening joint is an ideal ductile joint, the ductile flange-weakened joint with reasonable parameters has strong ductility, and the influence of the weakening of the flange on the bearing capacity of the specimen can not be completely neglected.
