摘要
国内外对于钢——混凝土界面粘结滑移性能的试验和理论研究一直在不断深入和完善,基于已有的较成熟理论的型钢混凝土界面粘结性能研究,总结了相关试验方法;对于加载初期,界面粘结应力沿锚固长度呈指数分布这一理论,通过比较两种计算公式下粘结应力曲线与实测曲线的吻合程度,得出采用能量法推出的公式更好的结论,对以后相关钢——混凝土光滑界面粘结应力试验研究具有一定参考意义.
Experimental and theoretical research of the former about steel-concrete bond-slip performance has been further and perfect.Based on the existing theory of SRC interface bond properties research,this paper summarizes the related test method.For the initial load,with the assumption that bond stress is exponentially distributed along the longitudinal length and by comparing two curves with the measured bond stress under the curve of the degree of fit,the energy method introduced in the formula can provide better conclusions.It has certain reference value for the study of future steel-concrete smooth interface bond stress test.
