THE SHEAR BEHAVIOR OF CONCRETE BEAM REINFORCED WITH ECC AND FRP GRID
-
摘要: 对纤维网格和ECC组合材料进行抗剪加固试验,通过与普通钢筋混凝土、碳纤维布加固钢筋混凝土试件的对比,研究不同试件的裂缝发展情况、极限挠度、极限承载力以及破坏模式,为ECC及纤维网格等新材料在结构加固工程中的应用提供新的思路。Abstract: In this paper,the shear behavior of concrete beam reinforced with engineered cementitious composites(ECC) and FRP grid is studied for the first time and is compared with the behavior of a beam reinforced with steel and CFRP sheet.The results from the research on crack development,ultimate deflection bearing capacity and failure mode of different specimens are valuable for further application of strengthening technology and the development of design guidelines for ECC and FRP grids.
