SCPS-model Validation Based on a Database of Naturally Corroded Prestressing Strands

Chloride-induced corrosion of prestressed concrete (PC) structures is worldwide recognized as a one of the main causes triggering the structural performance reduction of PC members over time. To ac-count for this issue, the accurate estimation of the mechanical properties decay of corroded prestressing reinforcement plays a crucial role. To provide model uncertainties estimation useful for reliable assess-ment of corroded PC members, the paper presents a further validation of the novel SCPS-model, based on an updated test database on naturally corroded strands collected by Authors from scientific literature. As revealed by the statistical analysis outcomes, the SCPS-model is confirmed as a useful tool for the daily engineering practice for the prediction of the residual tensile response of corroded strands
