摘　　要：在完成3块CFRP-PCPs复合筋混凝土板和1块普通混凝土板竖向荷载的静力加载试验的基础上,运用ANSYS对试验进行非线性有限元模拟及仿真分析,对我国现行的《混凝土结构设计规范》中应用于预应力混凝土梁的裂缝宽度计算公式进行了修正,给出了适合CFRP-PCPs复合筋混凝土单向板的裂缝建议计算公式,本文试验试件的实测数据和应用建议公式计算结果对比表明,试验值略小于计算值,较安全.Based on the vertical and static load test, which uses 3 pieces of CFRP - PCPs composites reinforced concrete slabs and 1 piece of normal concrete slab, and the nonlinear finite element simulated analysis of the test by using the ANSYS, this paper amends the formula used in pre-stressed concrete beam of crack width by the code for design of concrete structures and gives the crack calculation formula which is suitable for CFRP- PCPs composites reinforced concrete slabs. Comparing the measured data formula calculation results, it shows that the test result is security. of test specimens with the application recommended smaller than the calculated value, so the formula is
