Seismic analysis of the arch dams

Proper seismic evaluation of dams resistance against breaking, can prevent great financial losses and fatality which is required to precise estimates of forces especially the hydrodynamic pressure. The isogeometric method is a new analysis framework which is used to solve various engineering problems. In this study, it is tried to simulate the fluid-structure interaction and using the isogeometric method to evaluate the hydrodynamic pressure of an arch dam. Results have been compared with the analytical and finite element methods. The resulted Root Mean Square Error (RMSE) equal to 0.00216 confirm the accuracy of isogeometric method.
