Non-Linear Dynamic Analysis of a Reinforced Concrete Bridge Column under Vehicle Impact Loading

Abstract:

3D nonlinear impact analysis of a reinforced concrete bridge column under truck impact loadings was performed in this study. Three different boundary conditions were considered in order to investigate the effect of superstructures for the integral column during the impact. A fixed condition at bottom and restrained in a loading direction at top (Model I) showed the largest damaged area and dominant failure mode of the column was shear. However, Model II (Model I with released at top) showed smaller damage and dominant failure modes were flexure rather than shear. In Model III, it was found that the superstructure intensifies the shear and flexural damages to the column due to the dynamic movement of the superstructures
