Public ISBD [article]  in Journal of engineering mechanics > Vol. 138 N° 10 (Octobre 2012) . - pp. 1288–1297. Titre : Seismic response of asymmetric rectangular liquid-containing structures Type de document : texte imprimé Auteurs : Najib Bouaanani, Auteur ; Damien Goulmot, Auteur ; Benjamin Miquel, Auteur Année de publication : 2012 Article en page(s) : pp. 1288–1297. Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Seismic  response  Fluid-structure  interaction  Liquid-containing  structures  Tanks  Reservoirs  Analytical  formulations  Frequency  response  Time-history  response  Hydrodynamic  pressure  Finite  elements Résumé : A new formulation to investigate the seismic response of symmetric and asymmetric rectangular liquid-containing structures is developed and validated in this paper. The proposed method is based on a substructuring approach, where the flexible liquid-containing structure is modeled using finite elements, while the impulsive effects of the fluid domain are modeled analytically through interaction forces at the fluid-structure interfaces. The technique takes account of geometrical or material asymmetry of the liquid-containing structure, fluid compressibility, and energy dissipation through reservoir-bottom absorption. The formulation is presented in such a way that it can be easily coded into a practical and computationally efficient program and is applied to illustrative examples highlighting the effects of geometrical and material asymmetry on the dynamic responses of liquid-containing structures. The obtained frequency- and time-domain results are successfully validated against advanced finite-element analyses.
