“…Numerous researchers have investigated and reported failure (sliding) mechanism of dams using different approaches [41][42][43][44][45]. It can be concluded from the literature that, there is a direct relationship between opening cracks and sliding (failure) mechanism.…”

In analysis of different types of dams, i.e. arch, gravity, rockfill and Roller Compacted Concrete (RCC) dams, the effect of hydrodynamic water pressure as an effective factor must seriously be taken into consideration. In present study, the hydrodynamic effect is precisely deliberated in RCC dams and compared to hydrostatic pressure effect. For this purpose, Kinta RCC dam in Malaysia is selected and 2D finite element (FE) model of the dam is performed. The Lagrangian approach is used to solve the dam-reservoir interaction, fluid–structure interaction (FSI), and in order to evaluate the crack pattern, Concrete Damaged Plasticity (CDP) model is implemented. Comparisons show that hydrodynamic pressure significantly changes the dam behaviour under seismic excitations. Moreover, the hydrodynamic effect modifies the deformation shape of the dam during the ground motions, however, it increases the magnitudes of the developed stresses causing more extensive tension crack damages mostly in the heel and upstream zones of the dam.

“…Mirzabozorg and Ghaemian [14] examined the crack profile in the dam using smeared crack approach. Ftima and Leger [15] investigated the stability of cracked concrete dams under seismic excitation by means of rigid block model. A continuum damage model based on continuum damage mechanics was developed by Silva and Castro [16] to represent the nonlinear behaviour of the quasi-brittle material.…”

“…Thus, for dynamic analyses of dam-reservoir systems involving more complex situations, several formulations have been improved and, among them, the finite element method (FEM) is a robust technique. In the works by Chopra et al (1981), Hall and Chopra (1982), Sharan (1987), Ftima and Léger (2006) and many others, analytical and FEM analyses involving the dynamic effects on DRI are presented. In Brazil, many studies on dams, dynamic structurefluid interaction and related studies have been developed, as for example, the works of Pedroso (2003), Silva (2007), Silveira et al (2018), Mendes et al (2021), Silveira et al (2021), among others.…”
