abstract

in this paper, time-domain dynamic analysis of dam - infinite reservoir is studied. a numerical method, discrete singular convolution (dsc), which seems to be efficient and simple, has been used to model the mixed boundary conditions. after a brief introduction, dsc is applied to model the equation of motion of fluid-structure with constant cross section subjected to el-centro (1940) earthquake. to show the accuracy and reliability of dsc method, the results have been compared with the lee & tsai method as a benchmark. the results show the competency of the proposed method to model dam-reservoir systems.
