摘要
针对国内外有关钢筋混凝土牛腿的研究现状,分析钢纤维钢筋混凝土牛腿的研究进展,详细介绍国内外规范中有关钢筋混凝土牛腿设计的方法,旨在提高牛腿开裂荷载,控制裂缝宽度并提高延性。
According to the studying status at home and abroad on the research of reinforced concrete corbels, the research progress of steel fiber reinforced concrete corbel was analyzed, the design methods of the reinforced concrete corbels in the relevant standards at home and abroad were detailedly introduced, in order to improve the corbel cracking load, control crack width and improve ductility.
