基于5根不同张拉控制应力和不同截面面积的CFRP-PCPs复合筋的混凝土梁在低周反复荷载下的试验，对CFRP-PCPs复合筋混凝土梁挠度进行研究，根据试验结果，提出了CFRP-PCPs复合筋混凝土梁挠度计算方法，对比表明试验结果与计算值吻合较好。试验表明，CFRP-PCPs复合筋混凝土梁相比于预应力CFRP筋混凝土梁，有效改善了构件的受力性能和变形能力。
基于5根不同張拉控製應力和不同截麵麵積的CFRP-PCPs複閤觔的混凝土樑在低週反複荷載下的試驗，對CFRP-PCPs複閤觔混凝土樑撓度進行研究，根據試驗結果，提齣瞭CFRP-PCPs複閤觔混凝土樑撓度計算方法，對比錶明試驗結果與計算值吻閤較好。試驗錶明，CFRP-PCPs複閤觔混凝土樑相比于預應力CFRP觔混凝土樑，有效改善瞭構件的受力性能和變形能力。

Based on different tension control stress and different cross-sectional dimension of CFRP-PCPs composite reinforced con-crete beams,cyclic loading were tested on five concrete beams.Deflection of composite reinforced concrete beams of CFRP-PCPs is inves-tigated.According to the experimental results,a deflection expression is put forward.Comparison with experimental results showed reason-able matching the calculated values.The experimental results show that compared with the concrete beams of prestressed CFRP tendons , the concrete beams of CFRP-PCPs composite tendons effectively improves the structure of the force performance and deformation capacity.
