型钢混凝土粘结强度的研究

Study on the bond strength of SRC structures

通过假定型钢混凝土粘结滑移层的剪切破坏机构,在考虑节理单元厚度为零的基础上,采用上限理论对型钢混凝土粘结强度进行理论推导,得到了型钢与混凝土粘结剪切强度的上限解,并确定了其主要影响因素.本文可对型钢混凝土粘结滑移性能的进一步试验研究和理论分析提供参考.

In this paper, based on taking as zero the thickness of the link element between steel and concrete, the theoretic solution for bond strength of SRC structures is deduced with assuming a reasonable failure mechanism of the adhesive layer by using upper bound theorem of plastic limit analysis. The major factors that affect the bond strength are also determined. This paper will be helpful for the further experimental researches and studies on the bond-slip behaviors of SRC structures
