FINITE ELEMENT ANALYSIS OF CORRODED REINFORCED CONCRETE BRIDGE PIERS UNDER CYCLIC LOADING
This paper investigated the dynamic behaviors of corroded Reinforced Concrete (RC) bridge piers by Finite Element Method (FEM) simulation.The Damaged Plasticity Model for concrete,the Kinematics hardening model for rebar and the nonlinear spring element for bond-slip behavior between the longitudinal reinforcement and concrete were applied.The corrosion effects were simulated by reduction of rebar area,concrete cover strength,and bond-slip strength between reinforcement and concrete.Then,the corroded RC bridge pier model considering different axial load ratio was established,and the simulated results were compared with the test results.It was found that the simulated hysteretic curves,skeleton curves and stiffness degradation curves were well accord with the test results,however,the nonlinear spring element in FEM softerware could not take into the effect of accumulative cyclic damage degradation,and further investigation is urgently needed to capture this phenomenon.
