摘要
为了研究型钢剪力架在板柱节点抗冲切性能中的作用,采用ABAQUS有限元软件对75组配置型钢剪力架的方钢管中柱节点进行非线性有限元分析;结果表明:型钢剪力架可以有效提高板柱节点抗冲切承载力,根据计算结果对型钢剪力架长度给出建议值,对型钢剪力架的选取给出建议,并在《混凝土结构设计规范》(GB 50010—2010)抗冲切公式的基础上,通过数据拟合得到型钢剪力架板柱节点抗冲切计算公式,与有限元计算结果拟合良好,对实际工程应用提供了理论依据。
This paper concerned about the behavior of the concrete filled tube （CFF） column to flat slab connections with shearheads through the ABAQUS finite element analysis of 75 full-scale test. The results showed that the connections with shearheads could improve the punching shear strength of RC fiat plate. The responsible length of shearheads was proposed in this paper by 2（b＋2h0） , and the advice of how to choose the shearheads was mentioned. Based on the formula of punching shear in 〈code for design of concrete structures〉 （GB50010-2010）, the new formula was proposed by data fitting considering the function of shearheads. This result can provide a theoretical basis for the practical engineering due to its good fitting degree.
