Abstract

Large-scale composite bumper system (LCBS) for bridge piers can be used as protection facilities against ship collision. The segment of LCBS is made of glass fiber-reinforced polymer (GFRP) skins, GFRP lattice webs, polyurethane (PU) foam cores, and ceramsite filling materials. In present paper, an in-depth analysis of performance evaluation of LCBS is conducted for a cable stayed bridge using a nonlinear explicit dynamic finite-element analysis program (ANSYS/LS-DYNA). Typical collision cases for both protected and unprotected bridge piers are investigated. The maximum impact force and impact duration are discussed in detail. The simulation results indicate that LCBS can effectively increase the impact time of ship-bridge collision and significantly reduce the peak collision forces. Overall, the LCBS provides a new idea to the design of anti-collision system for waterway bridges.
