摘要
为了探究钢-混凝土组合梁栓钉剪力连接件构造参数对其抗剪承载力的影响,采用ABAQUS有限元软件建立了数值分析模型,获得了荷载-滑移曲线,并与经验公式计算比较,二者吻合较好;通过改变结构的混凝土强度等级、栓钉直径、栓钉屈服强度和栓钉长度等构造参数,分析了栓钉抗剪承载力的变化规律。结果表明:栓钉剪力连接件的抗剪承载力随着混凝土强度等级、栓钉直径、栓钉屈服强度的增大而提高。
In order to explore the effect of structural parameters on shear strength of steel concrete composite beam stud shear connectors,the numerical analysis model is established by ABAQUS,and the load slip curve is obtained,coincident with the simulation of the empirical formula. By changing the structural parameter of concrete strength,the yield strength of stud,diameter and length of stud,the variation of shear bearing capacity is analyzed.The results show that shear capacity enhances with the increasing of concrete strength,the yield strength of stud,diameter and length of stud.
