| 摘 要： | 为了解决桥梁结构中日益严重的钢材锈蚀问题和降低初始造价,纤维增强聚合物(Fiber Reinforced Polymer,FRP)-混凝土组合结构被认为是一种最有效的组合形式。文中首先从主要组合形式及其相关研究等方面回顾了FRP-混凝土组合梁/板系统的国内外研究现状,其次介绍了FRP-混凝土组合梁/板系统的3种常用分析方法和3种优化失效模式及相应的延性特征,接着列出了FRP-混凝土组合梁/板系统在国内外桥梁工程中的具体应用,最后探讨了该组合系统在今后研究中需要解决的一些问题。

| Abstract: | To solve the corrosion of the reinforcing steel in the bridge engineering and reduce the initial cost,hybrid Fiber Reinforced Polymer(FRP)-concrete structure has been considered as the most effective composite form.Firstly,a state-of-the-art survey of hybrid FRP-concrete beam/deck systems is reviewed from the aspects of the main composite forms and their studies.Secondly,three typically analytical methods and three types of optimized failure modes and their corresponding ductility for hybrid FRP-concrete beam/deck systems are introduced.Thirdly,applications of hybrid FRP-concrete beam/deck systems in the bridge engineering are presented.Finally,the several problems in the future research on the hybrid systems are put forward. |
