Résumé
Civil construction are subjected to live loads, and sometimes to earthquake or explosion inducing severe degradation. Consequently, the evaluation of reinforced concrete structure damages give an adequate help to decide either to replace or to repair à structure. This study presents an original way to estimate the state of damage of a construction, using a pertinent damage indicator. This factor is derived from internal indicator evaluated locally in critical cross-sections. Comparison between simulations and experimental data give good results in the way to establish the minimum required level for repairing.
