One‐Dimensional Model for Multi‐Barge Flotillas Impacting Bridge Piers
Abstract: The serious consequence of barge‐bridge collisions necessitates the study of barge impact loadings on bridges. This article introduces an elastoplastic spring‐mass model for the analysis of multi‐barge flotillas colliding with bridge piers at zero angle of attack. The model accounts for the essential factors pertaining to barge/flotilla impacts, such as pier geometry and stiffness, and dynamic interaction between barges. A method to identify the elastoplastic behavior of barge crushing is also presented. The proposed method generates impact force time‐histories for a multitude of flotilla configurations in a matter of minutes, which is especially valuable in probabilistic analysis requiring many collision simulations. The results from this study are compatible with the respective impact time‐histories produced by exhaustive finite element simulations. A bridge pier impacted by a three‐barge and a 15‐barge flotilla is studied.
