| 摘要： | This report consists of the analytical studies involved in the development of efficient and optimized Fiber Reinforced Polymer (FRP) bridge decks for use on movable bridges. The study is presented in two parts. Part A: 'Tube' and 'sheet' Models, and Part B: 'Monolithic' models. The two parts follow a parametric study approach, while utilizing the Finite Element Software ANSYS for all the analysis. The bridge deck systems developed are subjected to both static and dynamic loading conditions, amongst other variations in cross-sectional parameters, boundary conditions, and load combinations. The study concludes that while the existence of high-localized shear stresses is a critical consideration, especially with regards to designing a suitable connection between the bridge deck and the underlying stringers, the 'monolithic' models were found to be structurally more efficient. |
