Abstract

9 specimens of steel reinforced recycled concrete are designed to explore the effect of four factors as the cover thickness of section steel, the embedded length of section steel, the recycled aggregate concrete strength, and the lateral stirrup ratio on bond slip between section steel and recycled aggregate concrete. The test results show that the failure modes of recycled aggregate concrete are as similar as normal concrete; three formulas are proposed for the bond stress between section steel and recycled aggregate concrete, which are fitting well. The mathematical model of bond stress-slip is established through analysis, and the predicted curve is close to the test curve. The research results provide the basis for the numerical simulation analysis of the bond slip for the recycled aggregate concrete under the full replacement ratio.
