| 摘要： | The bond stress-slip relation between steel bars and concrete under reversed loading is very important for the seismic analysis and rehabilitation of concrete structures. In this study, an experimental investigation has been conducted to study the hysteretic bond response of deformed bars under uniaxial lateral pressure. Based on the experimental results, the variation of the bond parameters of reinforced concrete under different reversed loading conditions, uniaxial lateral pressures, and bar diameters were examined. It was found that the decay in the peak bond stress and frictional resistance is greatly influenced by lateral pressure and the bar diameter. Moreover, an empirical bond stress-slip constitutive model for reinforced concrete under reversed loading was proposed and validated against experimental results. |
