摘要

摘要: 为研究弱角钢对装配式钢结构框架中全螺栓连接双角钢-抗剪腹板式梁柱节点抗震性能的影响以及此类节点的震后修复水平,设计了2个足尺节点试件和1个修复试件,通过在梁端施加低周往复荷载的拟静力试验及数值模拟分析,研究节点的变形过程及破坏形态,分析节点的滞回曲线、刚度退化曲线、延性及耗能等抗震性能指标。结果表明:节点试件破坏主要集中在角钢及加劲肋的位置;节点试件延性系数达到6~9,具有较高的延性水平;角钢厚度增加4 mm,试件初始刚度可提高73%,承载力也有所提高;修复后节点耗能能力可达到原有试件的80%。

Abstract: In order to study the influence of weak angle steel on the seismic performance of beam-column joints with reinforced webs connected with fully bloted doble-angle steel and the post-earthquake repair level of such joints, two full-scale joint specimens and one repair specimen were designed. The deformation process and failure mode of the joints were studied by quasi-static test and numerical simulation analysis with low quasi-static load applied to the beam ends. The seismic performance indexes such as hysteresis curve, stiffness degradation curve, ductility and energy dissipation were analyzed. The results showed that the failure of joint specimens was mainly concentrated in the position of Angle steel and stiffening rib. The ductility coefficient of joint specimens was 6-9, which had a high ductility level. When the thickness of angle steel increased by 4 mm, the initial stiffness and bearing capacity of the specimen were increased by 73%. The energy dissipation capacity of the repaired joint could reach 80% of the original specimen.
