| 摘 要： | 由推出试验研究了型钢轻骨料混凝土界面相对滑移。通过在型钢和混凝土表面粘贴应变片获得了局部滑移试验曲线。根据型钢微段受力平衡推导了各级荷载下加载端滑移的计算公式,由试验曲线拟合了局部滑移沿锚固长度的分布曲线,给出了滑移分布指数特征值表达式。结果表明局部滑移计算曲线和试验曲线吻合较好。

| Abstract: | The interface relative slip is studied by push-out test.The gauges were arranged on the steel section and concrete surface,and local slip curves were acquired.The loading end slip formula under different load grade is deduced according to the force equilibrium of the steel section free body.The local slip formula along anchorage length is fitted based on the test curve.Results indicate that calculative curves agree well with the test results. |
