摘　　要：介绍了钢筋代换的规范要求、代换原则及其注意事项,并依据《混凝土结构设计规范》中钢筋混凝土构件最大裂缝宽度计算公式,以钢筋代换前后"裂缝相当"原则,分别讨论了相同强度等级钢筋代换前后配筋率之间的关系和不同强度等级钢筋代换前后钢筋直径之间的关系,以期为工程技术人员进行具体操作积累经验。It introduces the norm requirements, replacing principles and the attentions in it of steel bar replacement. It introduces the relation between reinforcement ratio before and after the steel bar of the same strength replacement and the relation between reinforcement ratio before and after the steel bar of different strength replacement according to the maximum crack width calculation formula of Reinforced Concrete Parts in Concrete Structure Design Norm with the principle of the same crack before and after steel bar replacement, so as to accumulate experience for technicians.

关 键 词：钢筋代换 裂缝 配筋率 钢筋直径
