摘要：	Massive waterway vessels such as barges regularly transit navigable waterways in the U.S. During passages that fall within the vicinity of bridge structures, vessels may (under extreme circumstances) deviate from the intended vessel transit path. A vessel that has become aberrant may subsequently collide with any nearby bridge substructure components (e.g., piers). When vessel-bridge collisions occur, large lateral dynamic forces are exerted upon the impacted bridge substructure component. The occurrence of collision-induced bridge failures has led to requirements for the design of bridges for vessel collision in the U.S. Over the past decade, significant advances have been made by a group of researchers and engineers at the University of Florida (UF), in collaboration with the Florida Department of Transportation (FDOT), toward the development of design-oriented vessel bridge collision analysis techniques. Based on these collective efforts, the current project was undertaken to implement computationally-efficient numerical modeling capabilities in the bridge finite element analysis software FB-MultiPier (FBMP) for use in calculations of impact design loads and predictions of bridge response. Contained in this report is detailed documentation of the graphical and analytical FBMP development of a simplified bridge modeling technique and a numerically efficient nonlinear dynamic vessel collision analysis technique. The newly implemented software features have been validated from a correctness of coding standpoint, and the predictive capabilities of the features have been demonstrated. By making use of the validated FBMP new features, bridge engineers can rapidly produce and conveniently quantify vessel collision analysis results that account for dynamic phenomena.
