Service Life Prediction and Lateral Bearing Capacity Analysis of Piles Considering Coupled Corrosion-Temperature Deterioration Processes

High temperatures can enhance the chloride diffusion coefficient and this poses a threat to reinforced concrete (RC) piles. This study intends propose predictive models that evaluate service life lateral bearing behaviour of piles subjected marine environments varying temperatures. The show temperature accelerate rate increase concentration free in concrete. distribution law is obtained by considering ageing effect as well. Deterministic probabilistic are proposed assess time corrosion initiation propagation. stiffness degradation introduced analysis capacity RC results high decrease spans from deterministic methods similar; however, predictions latter more conservative. Temperature current density boost products, which leads pile cracking. rust appearing on steel surface would make drop sharply. conducted perspectives shear force, displacement moment
