Study on Bond-Slip Performance of Corroded Reinforced Concrete Members

Abstract:

According to pull-off test on reinforced concrete specimens with different corrosion rate, their failure patterns, relationship between bonding strength and slippage, variation laws of bonding strength and slippage are studied. The calculating formula of reduction coefficient of bonding strength and slip ratio is proposed. Based on these studies, constitutive model of bond-slip performance for corroded reinforced concrete is set up. It can be seen after verification and analysis that calculated results of this model agree well with trial values, which suggests that the bond-slip constitutive model of this paper is reliable and universal.
