Numerical analysis of the Dukan dam under the influence of assumed seismic loads

Abstract

Dukan dam is an important hydraulic structure in Iraq used for water storage, flood control, and electricity generation. During earthquakes, this dam can be subjected to varying degrees of damage depending on the intensity and duration of the seismic event. In this article, Dukan dam will be analyzed during an assumed earthquake using the ABAQUS software. The behavior of the dam under the seismic load will be investigated. In this process, a two-dimensional finite element model of the central part of the dam, containing the maximum dam height, was created, taking into account the geometric parameters of the model, types of finite elements, material models, and boundary conditions. An analysis was performed for the dam section using the static analysis, seismic effect analysis, and hypothetical failure zones of the dam were identified.
