R\u00e9sum\u00e9<\/strong><\/span><\/h3>\n
Les travaux pr\u00e9sent\u00e9s comportent deux volets majeurs. Le premier concerne la caract\u00e9risation d\u2019\u00e9l\u00e9ments de murs pour lesquels le comportement vis-\u00e0-vis d\u2019un chargement lat\u00e9ral est encore m\u00e9connu. Sont trait\u00e9s dans ce cadre les portiques en b\u00e9ton arm\u00e9 avec panneau de ma\u00e7onnerie, la ma\u00e7onnerie de briques creuses sur laquelle un mat\u00e9riau de renforcement ou un mat\u00e9riau de r\u00e9paration est appliqu\u00e9. Ces deux derniers cas visent \u00e0 fournir des solutions combinant les r\u00e9habilitations \u00e9nerg\u00e9tique et structurelle des b\u00e2timents, pour les structures saines comme endommag\u00e9es. Les mod\u00e8les num\u00e9riques correspondants ont ensuite \u00e9t\u00e9 d\u00e9velopp\u00e9s afin de mesurer l\u2019effet de certaines variantes. Les limites de la mod\u00e9lisation et les pistes d\u2019am\u00e9lioration ont \u00e9galement \u00e9t\u00e9 d\u00e9velopp\u00e9es. Le second volet concerne le diagnostic structurel par mesures vibratoires appliqu\u00e9 aux structures en b\u00e9ton arm\u00e9. La particularit\u00e9 de l\u2019approche d\u00e9velopp\u00e9e porte sur la quantification de la pr\u00e9sence des d\u00e9fauts, ainsi que leur incorporation dans les maquettes num\u00e9riques. Une premi\u00e8re partie concerne l\u2019application \u00e0 l\u2019\u00e9chelle d\u2019\u00e9l\u00e9ments de structure de types poteaux \u2013 poutres soumis \u00e0 un endommagement progressif. La diminution des fr\u00e9quences propres avec l\u2019endommagement, observ\u00e9 durant les exp\u00e9rimentations, confirme les r\u00e9sultats de la litt\u00e9rature. Des mod\u00e8les num\u00e9riques simplifi\u00e9s, bas\u00e9 sur une approche par facteur de fixation sont propos\u00e9s. Les facteurs de fixation et leur \u00e9volution au cours du chargement permettent de retrouver les fr\u00e9quences propres identifi\u00e9es exp\u00e9rimentalement, confirmant l\u2019efficacit\u00e9 de cette r\u00e9duction de mod\u00e8le. Une seconde partie porte sur l\u2019application de ces m\u00e9thodes \u00e0 l\u2019\u00e9chelle d\u2019un b\u00e2timent. Les verrous actuels sont d\u00e9gag\u00e9s, tels que l\u2019identification d\u2019un voisinage proche, les limites de l\u2019approche num\u00e9rique par \u00e9l\u00e9ments filaires ainsi que la n\u00e9cessit\u00e9 de d\u00e9velopper des facteurs de fixation vectoriels. Les perspectives destin\u00e9es \u00e0 lever ces verrous sont \u00e9galement pr\u00e9sent\u00e9es.<\/div>\n<\/div>\n
