The Corrosion Characteristics and Tensile Behavior of Reinforcement under Coupled Carbonation and Static Loading

摘要: This paper describes the non-uniform corrosion characteristics and mechanical properties of reinforcement under coupled action carbonation static loading. The two parameters, namely area-box (AB) value arithmetical mean deviation (Ra), are adopted to characterize morphology pitting distribution from experimental observations. results show that loading affects reinforcement. Local stress concentration in corroded caused by tensile drives pit pattern be more irregular. orthogonal test finite element simulations shape depth significant factors affecting behavior Under condition similar mass loss ratio, maximum plastic strain increases with increase Ra load time-history significantly.
