Three-Dimensional Modal Analysis of Brezina Concrete Arch Dam, Algeria
Earth Science Research, 2012 In this paper, modal responses of the Brezina concrete arch dam, Algeria, are determined using the finite elements commercial packages ANSYS. To study the effects of the foundation soil, three 3D models have been created, the dam alone without soil, the dam-massless soil and the dam-soil with soil mass model. Moreover, a parametric study of the viscous

Rapid Reservoir Sedimentation of Four Historic Thin Arch Dams in Australia [PDF]
, 1998 Waters flowing in streams and rivers have the ability to scour channel beds, to carry particles (heavier than water) and to deposit materials. This phenomenon of sediment transport can affect substantially the design of reservoirs.

Damage analysis of arch concrete dams subjected to underwater explosion
Applied Mathematical Modelling, 2019 Abstract The nonlinear behavior of arch concrete dams subjected to underwater explosions was investigated. Pressure waves were spherically modeled using a 3-D finite element method. The nonlinear behavior of concrete was modeled using the concrete damage plasticity model.

Nonlinear Response of High Arch Dams to Nonuniform Seismic Excitation Considering Joint Effects
Journal of Engineering, 2013 Nonuniform excitation due to spatially varying ground motions on nonlinear responses of concrete arch dams is investigated. A high arch dam was selected as numerical example, reservoir was modelled as incompressible material, foundation was assumed as ...
