摘要
研究了轴压比、混凝土强度和配箍率对钢骨混凝土柱——钢筋混凝土梁框架边节点受力性能的影响.通过对节点承受低周反复荷载的有限元分析,确定了节点抗剪的各组成部分,提出了SRC框架边节点的抗剪承载力计算公式,式中确定了节点抗剪计算中混凝土强度影响系数,考虑了混凝土脆性和配箍率对节点承载能力的影响.
The experimental research of axial compression ratio, concrete strength and stirrup ratio on SRC frame side joints have been carried out in this thesis. Based on finite element analysis, the contribution of each part are determined and theory and the practical calculating formulas of shear bearing capacity of SRC frame side joints is derived. The factor of brittle property of high concrete strength influencing on the shear capacity is determined, and the influence of concrete strength and axial column load are included.
