Abstract
A numerical model of the bridge piers is achieved through the OpenSees program in order to predict the nonlinear global and local responses, expressed as displacements, forces and strains. The model is first evaluated by comparing the numerical forcedisplacement response with the corresponding experimental force-displacement response for different degrees of damages. Also, the limit states are compared to see how accurately the model predicts the local behavior as well. Experimental results of 39 columns tested under cyclic loading by several authors are used. These columns cover the main parameters of interest for typical bridge piers, such as geometry, longitudinal and transverse reinforcement ratio, and axial loading ratio. The results of this comparison have led to the conclusion that the numerical model can accurately predict the observed damage sequence and, therefore, the limit states that will be used to achieve the performance objectives. Safety coefficients are proposed to cover the error between the numerical model and experimental responses.
