Abstract：Bridge physical protection systems are typically used to reduce vessel impact loads to non-destructive levels or redirect aberrant vessels away from bridge piers. An efficient physical protection system is critical for safe operation of bridges and vessels. This paper focus on a performance evaluation of a new Floating Fender system used in a five span pre-stressed concrete bridge, by utilizing LS-DYNA. This new Floating Fender system can protect both bridge piers and vessels, and is composed of FRP box modules filled with rows of FRP tubes. It offers low initial cost, modular construction/repair, and low maintenance benefits. The study includes vessel collision analysis using an orthotropic FRP composite material models determined based on experimental data, including tension, compression, bending, and shear tests of FRP specimens. It is concluded that this new fender system has excellent energy absorbing capabilities and significantly reduces collision forces imposed on the bridge pier and colliding vessel.
