摘　　要：以国内外有关试验为基础 ,给出了集中荷载作用下钢筋混凝土梁斜裂缝宽度的计算公式 ,并利用文中的算式及相关试验数据对《混凝土结构设计规范》(GB5 0 0 1 0— 2 0 0 2 )Based on the concerning experiments of domestic and foreign scholars,a calculation formula of diagonal crack width of RC beams is proposed. And based on the formula and results of concerning experiments,the paper discusses whether the limit of diagonal crack width can be met during period of service when the concrete beam is designed with the shear capacity formula in Code for Design of Concrete Structures (GB50010—2002).
