Abstract

Abstract

Based on pull-out test of 20 reinforced concrete specimens with different corrosion rate,their failure patterns,r elationship between bonding strength and slippage,variation laws of bonding strength and slippage were studied,and calculating formula for the reduction coefficient of bonding strength and slip ratio was proposed.Based on which,constitutive model of bond-slip performance for corroded reinforced concrete was set up.Relative to other domestic and foreign constitutive models,the model which is efficient by confirmatory factor analysis is relatively resultful,and it is fit to be used in actual engineering items．
