Application of pseudo-symmetric technique in dynamic analysis of concrete gravity dams V. Lotfi Department of Civil and Environmental Engineering, Amirkabir University, Iran Abstract A new approach is presented for seismic analysis of concrete gravity dams in the time domain. The technique is based on symmetric formulation of dam-reservoir systems utilizing pressure degrees of freedom in the fluid domain. The method is explained initially in relation to other available techniques. Following from this, the analysis of a typical concrete dam is considered as a verification example by utilizing a modified program based on this technique. The methodology introduced is very convenient and can be easily implemented in general-purpose finite element programs with regard to their fluid-structure interaction modules. 1 Introduction There has been extensive research in relation to Fluid-Structure Interaction problem encountered in dynamic analysis of concrete dams. Some of these studies are formulated
