The mechanical characteristics of the above groups of matching have been investigated . corrosion behavior was studied both by experimental and numerical approaches . the mechanical properties of partial corrosion and entire corrosion in the reinforced concrete structure were analyzed 通过钢筋混凝土的腐蚀试验,本文研究了局部锈蚀钢筋和全部锈蚀钢筋在钢筋混凝土结构中的力学退化性能,并用“坑蚀”和“剥层”的有限元模型对其进行了数值分析。
