栓钉连接件抗剪刚度计算与荷载-滑移曲线方程

Shear stiffness calculation of stud connectors and load-slip curve equation

为了明确栓钉抗剪刚度的影响因素,采用m法对栓钉连接件抗剪刚度进行了理论推导,建立了荷载-滑移曲线方程,计算结果与试验值及数值模拟结果吻合较好。在此基础上,探讨了栓钉直径、高度和材料性质,以及混凝土强度对栓钉抗剪刚度的影响。研究结果表明:栓钉直径对栓钉抗剪刚度影响较大,栓钉高度、材料性质及混凝土强度对栓钉抗剪刚度影响较小。

In order to define the influencing factors of the stud shear stiffness, the theoretical derivation was car- ried out for the shear stiffness of stud connector by using m method, the load-slip curve equation was established, and the calculation results are in good agreement with the test and numerical simulation results. On this basis, the in flu- ences of the stud diameter,height and material properties and the concrete strength on the stud shear stiffness were discussed. The research results show that, the stud shear stiffness is greatly influenced by the stud diameter, but it is slightly affected by the stud height, material properties and concrete strength.
