Abstract To investigate the influence of corrosion of steel bar on the bonding performance between steel bar and concrete, 24 central pull-out test spe-cimens as well as other 6 specimens for compressive strength were cast. Pull-out test were conducted to study the bond behavior between concrete and steel bar which was corroded using current accelerate method to control corrosion with the expected corrosion rate of 0%,0.3%,0.5%,1%,2%,5%,8%,15%.The influence of corrosion rate on bond stiffness was studied by method of secant stiffness.The influence of corrosion on work of pull-out force before peak slip was also studied.A simplified three-stage test method and constitutive model of bond strength degeneration were proposed.Furthermore,a three-stage bond-slip constitutive relation was proposed considering influence of corrosion on residual bond strength. The test results show that degradation speed of bond stiffness between concrete and rebar can be divided into two stages after reaching peak.The work of pull-out force before peak slip decline at the beginning then increase and finally decrease with corrosion increasing.

Key words： reinforced concrete corrosion bond strength bond stiffness constitutive model
