Titre : Seismic risk : Structural response of constructions Titre original : Risques sismiques. Réponse des structures de génie civil Type de document : texte imprimé Auteurs : Jacky Mazars, Auteur ; Stéphane Grange, Auteur ; Cédric Desprez, Auteur Année de publication : 2012 Article en page(s) : pp. 223-246 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Earthquakes Seismic response Modal analysis Reinforced concrete structures Dynamic nonlinear behaviour Seismic vulnerability Retrofit of existing buildings Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : This paper presents numerical techniques for computing the response of reinforced concretes structures. From the one degree of freedom case and after the formulation of the equations of dynamic equilibrium, the general case is considered. Two main aspects are treated, the one related to the modal analysis which, in the linear regime, leads to the mode shapes and the natural frequencies, and the one related to the seismic vulnerability analysis which, in the non linear regime, is able to describe the damage location and the critical zones of a given structure. Applications show that the strategy opens on tools useful to design the reinforcement of existing building.

Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Three simplified modelling strategies are proposed to simulate the non linear behaviour of reinforced concrete (RC) structures submitted to severe loadings. The Equivalent Reinforced Concrete model (ERC) is suitable for very squat RC walls and it is based on the Framework method coupled with damage mechanics and plasticity constitutive laws. The multifiber Timoshenko beam can be used for slender or squat structures submitted to severe shear or torsion. Finally, the SSI macro-element coupled with the multifiber beam is able to reproduce soil structure interaction phenomena on the foundation and the structure.
