新型FRP-混凝土组合桥面板的初步设计
|
摘要
本文阐述了使用不同FRP材料与混凝土结合形成一种质轻、刚度大、耐腐蚀且经济合理的组合结构的基本设计思路,提出了一种新型的FRP-混凝土组合桥面板的结构形式,给出了FRP-混凝土组合桥面板的简化失效分析方法及其计算公式,并提供了FRP-混凝土组合桥面板的初步设计步骤。
The basic design concepts for structures combined with different fiber reinforced plastic materials and concrete are introduced in the present paper.This concept results in cost-effective composite structures with lightweight,high stiffness,excellent corrosion resistance characteristics.What is more,a new type hybrid FRP-concrete bridge superstructure is provided.Meantime,the methods of simplified failure analysis and theoretical formulas for the hybrid FRP-concrete bridge superstructure are presented.In addition,a preliminary design procedure is also provided.
