在现浇钢筋混凝土结构施工过程中,往往会遇到现场可供的钢筋级别、直径与设计要求不相符的情况,这时就需要对钢筋进行代换。在进行钢筋代换时,如果由于对设计意图或材料性能了解不够,或对现行结构设计规范的相关规定考虑不够全面,而采用了不恰当的钢筋代换,将对结构构件的适用性、耐久性甚至是安全性造成影响。本文对现浇混凝土 In the process of cast-in-place reinforced concrete structure construction, often encountered in the field available reinforcement level, diameter and design requirements do not match the situation, then you need to replace the steel. In the replacement of steel, if the design intent or material properties do not know enough, or the existing structural design specifications to take into account the relevant provisions is not comprehensive enough, and the use of improper reinforcement substitution, the structural components of the applicability, durability Sex and even security have an impact. In this paper, cast-in-place concrete
