Abstract

Abstract: Since large dams collapse can lead to catastrophic consequences on human's lives and properties, the reliable performance of such structures during a strong earthquake is extremely important. Therefore, applying reliable analysis methods for designing large dams and seismic evaluation of the existing dam is crucial. The present study investigates the behavior of a concrete arch dam during the maximum credible earthquake "MCL" through non-linear time history analysis. A 30-meter height concrete arch dam was simulated in SAP2000-academic version- using 3D solid elements. Rayleigh damping and plasticity-based five-parameter Willam-Warnke model, as a means of failure criterion, were taken into account during non-linear time history analysis. The results indicated that the seismic load combination had a significant impact on final stress distribution in which high tensile cracks penetrated over the upstream heel.
