Nonlinear Analysis of Shear Performance of Joints of Steel Reinforced Concrete Beam and Angel-Steel Concrete Column
【摘要】 从配置型钢锚脚的型钢混凝土梁-钢筋混凝土柱节点数值模拟结果出发,对比研究了型钢混凝土梁-钢筋混凝土柱节点、型钢混凝土梁柱节点及型钢混凝土梁-角钢混凝土柱节点的破坏模式和抗剪性能,然后对型钢混凝土梁-角钢混凝土柱节点进行参数分析,考察了轴压比n0、型钢腹板厚度tw、角钢配钢率ρa、节点钢板箍配箍率ρv及混凝土强度fc对此类节点受剪性能的影响,并基于大量参数分析和统计结果给出了型钢混凝土梁-角钢混凝土柱节点抗剪承载力计算建议,其结果可供相关工程实践参考。
【Abstract】 This paper conducted an analytical research on failure mode and shear performance of joints of steel reinforced concrete beam and reinforced concrete column,joints of steel reinforced concrete beam and column,and joints of steel reinforced concrete beam and angle-steel concrete column based on the caculated results of joints of steel reinforced concrete beam and reinforced concrete column with steel anchor.Then the parameters analysis for joints of steel reinforced concrete beam and angel steel concrete column was carried on.The axial compression ratio n0,steel web thichness tw,angle-steel ratio ρa,stirrup ratio of joint core area ρv,concrete strenght fc were investigated,and the design formula of shear capacity for the joint of steel reinforced concrete beam and angle-steel concrete column was given on account of a great number of analytical and statistic results.The results can provide a reference for engineering practice.
【Key words】 steel reinforced concrete beam; angle-steel concrete column; joint; shear performance;
