摘要: 采用一种新型的带蒙皮FRP格栅,在其上浇筑混凝土制备桥面板。采用换算截面法推导了带蒙皮FRP格栅-混凝土组合板截面在使用阶段的截面有效抗弯刚度,并通过材料力学的方法推导了板件跨中挠度的计算公式。依据相关规范进行带蒙皮FRP格栅-混凝土组合桥面板的设计并给出设计实例及计算方法。验算结果表明,带蒙皮FRP格栅-混凝土桥面板应用于混凝土-复合材料组合桥梁结构较为可行。

Abstract: This paper proposes a new FRP-concrete composite panel form-concrete panels strengthened by composite grid with skin. The effective bending stiffness of this kind of panels was deduced by the transformed section method. And the mid-span displacement was derived from mechanics of materials method. It brings up a whole structured design process of a sandwich structure bridge panel, and gives the design parameter of bridge panel. The checking results show that using concrete panels strengthened by composite grid with skin into girder-composite bridge panel is more feasible.

Key words: FRP skin, composite grid, mid-span displacement, bridge deck
