型钢混凝土临界保护层厚度研究

The analysis of critical concrete cover of SRC structure

通过建立拉断破坏模型、剪切破坏模型和基于塑性极限分析的上限定理,经过理论推导得出型钢混凝土的临界保护层厚度,并将所得结果与试验值、规范规定值进行比较,从而为型钢混凝土的粘结滑移性能的研究提供了重要参考。

Through the construction of tensile failure model and shear failure model, based on the upper bound theorem of the plastic limit anal ysis, the critical concrete cover is deduced and compared with the experimental and specification regulated data, this paper will be helpful for the further experimental researches and studies on the bond-slip behaviors of SRC structures.
