摘　　要：结构构件的延性与强度问题同等重要,为保证构件延性,必须对钢筋延性提出要求。本文在理论分析的基础上推导出钢筋混凝土矩形截面受弯构件的钢筋伸长率安全范围,为防止构件脆性破坏提供了思路和易行的控制方法。The ductility of structure and member is important as the intensity. Due to the ductility of member, the ductility of steel bar should be limited. With the analysis of theory, the safe extent of elongation of steel bar used in reinforced concrete flexural rectangle section member is calculated. This article provides a thought and a simple method to preventing the brittleness destruction of member.
