| 摘 要： | 基于5根不同张拉控制应力和不同截面面积的CFRP-PCPs复合筋混凝土梁在低周反复荷载作用下的试验,对比试验梁的裂缝分布与发展,在GB 50010—2010《混凝土结构设计规范》计算裂缝宽度的基础上,对平均裂缝间距和最大裂缝宽度计算公式进行参数修正,提出CFRP-PCPs复合筋混凝土梁在低周反复荷载下最大裂缝宽度计算公式,对比表明,试验结果与计算值吻合较好。

| Abstract: | Based on the tests of different tension control stress,pre-compressive strength and different cross-sectional dimension of 5 CFRP-PCPs composite reinforced concrete beams under low cyclic loading. It was compared the characteristics of fracture distribution and development. Considering the calculation method for crack width in the current national standard "Code for Design of Concrete Structuses "( GB 50010—2010) and according to experiments,the formula for calculating maximum crack width of the reinforced concrete beams of CFRP-PCPs under low cyclic loadings was given. The comparison showed that the test results agreed well with the calculated values. |
