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。
By the launch of the pilot study of steel lightweight aggregate concrete interface relative slip. The local slip test curve was obtained by pasting strain gauges on the surface of steel and concrete. Based on the force balance of the micro-section of steel section, the formulas for calculating the slippage at the loading end under all levels of loads are deduced. The distribution curve of the local slip along the anchorage length is fitted by the test curve, and the expression of the eigenvalue of the slip distribution index is given. The results show that the local slip calculation curve is in good agreement with the experimental curve.
