Feasibility Study of FRP Composite Deck-and-Stringer Bridges

摘要

A method for the analysis and design of FRP composite deck-and-stringer bridges is presented. The FRP decks considered consist of contiguous thin-walled box sections that are fabricated by bonding side-by-side pultruded thin-walled box beams and placed transversely over FRP composite stringers. A simplified design analysis procedure is developed, which can permit the designer to analyze, design, and optimize material architectures and shapes of FRP beams as well as various bridge deck configurations before their implementation in the field. Experimental studies are conducted, which verify the present analytical design method.
