混凝土碳化、钢筋锈蚀、保护层胀裂引起混凝土结构性能退化,在试验研究和非线性有限元分析的基础上,建立了锈蚀钢筋混凝土受弯构件正截面和斜截面承载性能分析方法和计算模型,通过实例分析了锈蚀钢筋混凝土受弯构件正截面抗弯、斜截面抗剪性能变化特征和规律。
The concrete carbonation, steel bar corrosion and concrete cover cracking are the main factors deteriorating the reinforced concrete structure. Based on finite element simulation and experimental study of corroded reinforced concrete flexural members, an analysis approach and calculation models for flexural and shear strength of corroded reinforced concrete flexural member are proposed. The varying character and rule of flexural and shear strength for corroded reinforced concrete flexural member are given by an example,
