摘要
本文从锈蚀钢筋混凝土受弯构件的破坏模式入手 ,分析其破坏机理、钢筋与混凝土的应力应变状态。考虑受压区钢筋锈胀力对钢筋周围混凝土抗压强度的降低 ,建立锈蚀钢筋混凝土构件承载力计算模型。
According to mode of failure of corroded reinforced concrete flexural members,me chanism of failure and stress\|stain state of reinforcement and concrete are ana lyzed.A decrease in strength of the compressive concrete around the bars due to corroded expansion force is considered,and a model for bearing capacity of corro ded reinforced concrete flexural members is established. \[
