Abstract:

Results of a detailed analysis to evaluate the potential horizontal and vertical movements of the piers of George P. Coleman Bridge, Virginia, in the event of ship impact are presented in this paper. Two-dimensional (2-D) and three-dimensional (3-D) total stress elasto-plastic finite element analyses were conducted. It was found that the 2-D analysis underestimates the resistance of the piers to ship impact. Based on 2-D and 3-D analyses, the paper presents a practical methodology and correlations to help extrapolate the 2-D results to account for 3-D effects.
