摘要：	Most movable bridges within Florida have decks that are open grid steel decks, which are often cited for poor rideability, susceptibility to fatigue, and high noise levels. Also, maintenance of these deck systems is increasingly difficult due to high maintenance costs and prolonged periods of traffic delay. Florida International University researchers investigated a number of alternative bridge deck systems, which had been evaluated in prior research, to lay a complete foundation for further design and implementation procedures. The main objectives of the deck alternatives were to meet the loading and serviceability requirements while satisfying a maximum 21-pound-per-square-foot weight requirement.
