摘要
根据国内外关于型钢混凝土粘结性能的试验研究 ,对型钢混凝土结构 (SRC结构 )中型钢 混凝土的粘结强度进行了分析和探讨 ,并对型钢混凝土粘结应力沿锚固长度的分布规律进行了分析 ,从粘结力的力扩散角度对型钢混凝土构件的临界保护层厚度进行了理论推导 ,提出了一种型钢 混凝土粘结强度的计算方法 ,并建立了粘结强度和极限荷载的计算模式。与已有的试验结果进行对比验证 ,符合较好 ,可为型钢混凝土结构中型钢
According to the former experiments research on bond slip performance,the distribution of the bond stress between steel shapes and concrete in SRC structures is analyzed in detail,based on which bond strength between steel and concrete in SRC structures is theoretically derived.A calculation method of bond strength and ultimate load of bond fracture is established,which is in good agreement with the experiment results.All these may contribute to the further analysis of performance of bond relation between steel and concrete in SRC structures.
