摘要
以弹性基地梁模型为基础,推导了栓钉连接件的抗剪刚度计算公式。利用42个栓钉连接件的数值模拟计算结果,本文拟合了地基参数的计算公式。此外,本文进一步推导了栓钉连接件在塑性阶段的抗剪刚度。最后,将模型与试验结果对比,两者吻合度较好。
The stiffness formula of stud connector was deduced based on the elastic foundation beam model. The calculation formula of foundation parameters was obtained by fitting the numerical simulation results of 42 stud connectors. Furthermore, the stiffness formula of stud connector at the plastic stage was deduced. Finally, the results of the model were in a good agreement with that of the test.
