摘要
在钢筋增强PVA纤维水泥基复合材料梁相关试验数据的基础上,对现行GB50010—2010《混凝土结构设计规范》、SL191—2008《水工混凝土结构设计规范》和JTJ 267—1998《港口工程混凝土结构设计规范》中钢筋混凝土梁最大裂缝宽度计算公式进行改进,提出了钢筋增强PVA纤维水泥基复合材料梁最大裂缝宽度的计算方法与设计建议。与基于JTJ 267—1998《港口工程混凝土结构设计规范》的计算方法相比,基于其他两种规范的建议公式的最大裂缝宽度计算值与试验值更为吻合。
Based on the experimental data of reinforced PVA fiber reinforced cementitious composite beams,the calculation formulas of maximum crack width of reinforced concrete beam in design code for concrete structures (GB 50010-2010 ), design code for hydraulic concrete structures (SL 191-2008) and design code for harbor engineering concrete structures (JTJ 267-1998 ) are modified,The calculation methods and the design suggestions of the maximum crack width of reinforced PVA fiber reinforced cementitious composite beams are put forward.Compared with the calculation method based on the design code for harbor engineering concrete structures (JTJ 267-1998 ), the calculated value and experimental value of the maximum crack width of suggested formulas based on the other two kinds of codes are more consistent.
