摘　　要：CFRP-PCPs筋混凝土受弯构件作为一种新型混凝土结构,具有延缓裂缝开展,减少挠度以及裂缝宽度的优良特点。从造价方面考虑,为了获得其最简配筋量的计算方法,参考国内外有关文献,提出利用线性规划的相关知识,求出其相应可行域,得到最经济配筋面积的方法,并辅以算例说明。为了验证提出计算式的正确性,进行了7根CFRP-PCPs筋混凝土受弯构件的试验,试验破坏模式为适筋梁破坏,与设计相符合。此种设计方法对今后类似试验的构件设计起到参考作用。The flexural members of CFRP-PCPs reinforced concrete as a new type of concrete structure,with the good characteristic of slow crack propagation,reducing deflection and the crack width. Considering from the cost to find out the economic quantity of reinforcement,reference relevant literature from home and abroad,using the knowledge of linear programming,the corresponding feasible region and the most simple reinforced area were found out,supplemented by examples to show that test to verify. To verity the proposed formulate,the experiment of7CFRP-PCPs concrete beam specimens for normal section flexural test. Experiments show that the failure modes are consistent with the cacluated results. Reference for the future component design of similar test were given.
