Seismic response of asymmetric rectangular liquid-containing structures. Bouaanani, N., Goulmot, D., & Miquel, B. Journal of Engineering Mechanics, 138(10):1288 - 1297, 2012. Analytical formulation;Hydrodynamic pressure;Liquid containing structures;Tanks;Time history response;
Paper abstract bibtex 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 fluidstructure 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. © 2012 American Society of Civil Engineers.
