Abstract EN
Flexibility of dam structure affects the hydrodynamic pressure acting on the dam.
Several approaches have been proposed to consider this effect.
Most of these approaches are involved with an iterative scheme.
Of course solving the total numerical model including the dam and the reservoir is the most accurate method, but it has certain deficiencies.
Using the frontal solution method of total model, dam structure, and fluid domain and keeping the interface degrees of freedom in the front is proposed in the current study.
Having the solution of the interface degrees of freedom, the structure and fluid may be analyzed separately.
The main advantage of the method lies in the fact that the accuracy of the results is the same as analysis of the total model, no iteration is necessary, combination of Lagrangian and Eulerian formulations for solid and fluid may be used, and the unknown variables are of the same order.
Performing the analysis in time domain extends the method to nonlinear analysis if required.
