A Fiber-Based Model for Seismic Performance of Reinforced Concrete Bridge Piers with Reinforcing Bar Corrosion
The corrosion of reinforcement negatively affects the serviceability and capacity of concrete structures and increases their vulnerability under natural hazards. In this paper, a fiber-based model is proposed for simulating the seismic performance of reinforced concrete structures subjected to corrosion. The fiber-based model was implemented in an open-source finite element program, OpenSees. Based on experimental observations, the corrosion damage was modeled by the modification of the uniaxial stress-strain relationships in the materials. In order to consider bond slip effects between the rebar and concrete, an analytical model was proposed to calibrate the parameters of the zero-length section element in OpenSees. Comparisons between simulated and measured responses of a series of specimens indicated that the proposed model is capable of simulating the seismic performance of corroded reinforced concrete bridge piers with reasonable accuracy and acceptable computational efficiency.
