型钢混凝土粘结机理与粘结强度的研究

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及影响粘结强度的主要原因进行了分析和探讨，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，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混凝土粘结性能的试验研究及实验设计中粘结强度的计算提供参考和依据。

Analysis of mechanism and strength of bond between steel and concrete in SRC structures

In this paper, the mechanism and strength of the bond between steel shape and concrete in SRC members and structures, the distribution of the bond stress, as well as the factors, which affect the strength of bond, were detailed analyzed. Based on the analysis and former experiments results, a calculating method of the bonding strength, which considered several main factors, and the calculating method of ultimate load were presented and approved in good agreement with the experiments results. All these may be helpful for the later experiments and researches on the mechanism of bond as well as the calculation of the bond strength between steel shape and concrete in SRC members and structures.
