Field and Laboratory Tests of a Proposed Bridge Deck Panel Fabricated from Pultruded Fiber-Reinforced Polymer Components
Two 7" deep FRP deck panels were manufactured and tested in a controlled service environment. The deck panels were 15' by 5' in plan, and were composed of ten 15' long, 6" by 6" by 3/8" standard pultruded FRP tubes. The tubes were sandwiched between two 3/8" thick standard pultruded FRP plates. The …

Development Of A Simplified Finite Element Approach For Frp Bridge Decks.
… bridges in Florida typically use open steel grid decks due to the weight limitations. However, these decks present rideability, environmental, and maintenance problems, for they are typically less skid resistant than a solid riding surface, create loud noises, and allow debris to fall through the …
