This study was conducted to evaluate the structural behaviour of Beris Dam under predicted seismic loading and the behavior of a dam under extreme loading cases such stresses and deformation of the dam. A LUSAS modeler and Dynamic Linear Analysis of Finite Element Method were presented to analyze the huge structure of the dam. A linear dynamic analysis of Beris Dam using five modes of shape for the dam is being conducted. As a results, the value of the maximum displacement is 18mm in the mode shape which mean it is acceptable and the performance of Beris Dam is considered satisfactory due to the value obtained. The stress behavior of Beris Dam is also satisfactory because of the value of the maximum normal stress and shear stress are 869.135 kN/m2 and 444.975 kN/m2 respectively which is less than allowable stress capacity of 900 kN/m2. This indicates that LUSAS 14 software is able to analyze the structure under seismic loading based on results obtained from linear dynamic analysis presented in this study.
