摘要
针对不带栓钉的混凝土剪力墙-钢梁T型连接铰接节点,借鉴混凝土抗冲切的理论分析方法,利用刚塑性模型假设,得到节点抗拔承载力计算公式,然后与试验结果进行对比,结果表明两者吻合良好;同时在试验验证的基础上,利用MSC.MARC软件对节点进行了变参数分析,进一步验证了理论计算精度。
For the concrete wall-steel beam T-plate pin joints without studs, based on the concrete punching theoretical analysis method and hypothesis of rigid-plastic model, the calculation formuia of uplift bearing capacity for this type of joint was derived, whose results were in good agreement with experimental results. Meanwhile, on the base of the verification of the experiments, parametrical analysis via MSC. MARC has been done; which further validates the precision of the formula.
