Characterization of 3D fluid-structure interaction effects in civil engineering applications. Gazarian-Page, C. & Bouaanani, N. In volume 5, pages 4542 - 4551, Montreal, QC, Canada, 2013. Civil engineering applications;Fluid-structure interaction problem;Hydrodynamic effect;Hydrodynamic pressure;Model and analysis;Reservoir systems;Simplified analysis;Threedimensional (3-d);abstract bibtex In recent years, the analysis of fluid-structure interaction problems has become of significant interest to civil engineering applications, in particular for hydraulic structures such as water gates, spillways and canal locks. The dynamic analysis of these types of structures can be carried out using finite element models in two or three dimensions. In many cases however, three dimensional (3D) coupled finite element models of structure-reservoir systems can be prohibitively complex, considerably increasing costs associated with actual modeling and analysis. Major difficulties arise mainly from the modeling of the fluid domain and associated boundary conditions. In this paper, we present a systematic characterization of 3D effects on the dynamic response of wall-water systems. For that purpose, we propose a new formulation based on a sub-structuring approach where the structure is discretized using conventional 3D-solid finite elements, while the fluid is modeled analytically by solving the wave equation governing hydrodynamic pressure. The proposed formulation is first validated against coupled finite element models including fluid-structure capabilities. The proposed method is then used to examine case studies of wall-water systems, investigate corresponding 3D hydrodynamic effects and assess the validity of reducing wall-water system's width for simplified analysis purposes.
