Title

Evaluation the Seismic Response of Concrete Arch Dam under Non-Uniform Excitation using Stochastic Method

Pages

  186-198

Abstract

 To investigate the seismic responses of dams due to ground non uniform displacements, the records of earthquake displacements are required. Such data is seldom recorded during a specific earthquake and in the most cases the recorded data in not sufficient for non-uniform analysis of a dam. In this study non uniform accelerations are generated using KanaiTajimi spectrum with considering wave passage, incoherent effects and coherence spectrum model. A 3-d finite element model of dam-foundation of Karun 4 arch dam as the highest dam in Iran is modeled. The model is analyzed under uniform and non-uniform generated accelerations and its responses are investigated. The results show that, Non-uniform excitation leads to differences in seismic response than uniform excitation on dam. It is indicated that considering Non-uniform excitation in seismic analysis increases the stresses and displacements on the dam body.
