【摘要】 通过钢筋内贴片粘结滑移试验,测得了轻骨料混凝土中变形钢筋加载端和自由端的相对位移、应力沿锚固长度的分布规律,进而得到了钢筋粘结应力分布规律.为轻骨料混凝土粘结机理研究及建立粘结本构关系提供了必要的基础.更多还原

【Abstract】 In the present study, difficulties on reinforcement′s stress measure were overcome by placing the strain gauge in the reinforcement bar. The distribution of the bond stress and relative slip along the anchorage length of reinforcement bar was calculated based on the test results. It lays the theoretical foundation for mechanics study of the lightweight concrete bond and the construction of its bond stress model.更多还原
