Prediction method for seismic damage of reinforced concrete bridge columns

Abstract

This research aims to determine the effect of loading pattern on the damage of a reinforced concrete bridge column. Five specimens were tested with uni-directional or bi-directional cyclic loading patterns combined with a constant axial load. In this report, a simple procedure to predict the damage and failure of a reinforced concrete column, that is subjected to an arbitrary seismic loading pattern, is proposed using the fatigue based damage model combined with the energy dissipation.
