Inter-comparison of experimental and numerical simulation results on mechanical behaviour of corroded beams

Abstract

ABSTRACT The “benchmark des poutres de la Rance” research project contributes to the study of safety margin re-assessment and to the monitoring of prestressed and reinforced concrete structures in aggressive environment. Several academic and industrial partners are involved in this project: CEA, EDF R&D, CEBTP, LCPC, LMDC, LMT, LML, GéM, OXAND and IETcc. These teams are involved in researches and studies related to the mechanical effect of corrosion and the damage in civil engineering concrete structures. The paper presents a critical comparison of the experimental results and the numerical simulations (tensile and 4-points bending tests) performed by the different project partners.
