摘　　要：鉴于国内外关于FRP筋混凝土板的实验研究、理论分析和数值模拟都很少,在介绍FRP筋混凝土板抗弯承载力的理论研究的基础上,对试件的破坏形态进行了描述,在考虑预应力度、FRP筋张拉控制应力等主要研究内容的影响下,研究了FRP筋混凝土板的承载能力的变化,并对普通钢筋混凝土板正截面承载力公式分析研究,推导出相应的FRP筋混凝土板破坏形态抗弯承载力计算公式.As experimental research, theoretical analysis and numerical simulation about FRP bars concrete plate at home and abroad are very few, this paper introduces the study of the theory of the flexural bearing capacity of FRP reinforced concrete plate, describes the damage form of specimens, considering prestressing degree, FRP bars tension control stress under the influence of the main research content, researches on the bearing capacity changes of FRP reinforced concrete plate. Therefore, through the study of the carrying capacity of FRP reinforced concrete board, and based on the analysis research of the ultimate capacity of ordinary reinforced concrete formula, this article deduces the corresponding FRP reinforced concrete plate failure pattern calculation formula of flexural bearing capacity.
