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.
In view of the experimental research on FRP reinforced concrete slab at home and abroad, the theoretical analysis and numerical simulation are very few. Based on the theoretical research on the flexural capacity of FRP reinforced concrete slab, the failure morphology of the specimens is described. The prestressing force and the tension control stress of FRP tendons, the change of bearing capacity of FRP reinforced concrete slab is studied. The formula of normal section bearing capacity of common reinforced concrete slab is analyzed and studied, and the corresponding FRP tendons Calculation formula of flexural capacity of concrete slab.
