纤维增强复合材料(FRP)作为混凝土结构的新型高性能增强材料,受到了国内外土木工程界的广泛关注.全FRP筋混凝土梁斜截面受剪承载力的计算需要考虑FRP纵筋和FRP箍筋的特殊影响.在大量试验研究的基础上,各国规范均提出了全FRP筋混凝土梁斜截面承载力的计算公式,其中包括中国规范(GB 50608-2010)、日本规范(JSCE 1997)、英国规范(BISE 1999)、意大利规范(CNR-DT 203/2006)、美国规范(ACI 440.1R-06)、加拿大规范(CSA.S 806-12).用这6种规范所提供的计算模型分别计算33根试验梁的斜截面承载力,并与试验结果作对比,以此评价这些方法的可靠性.
