Abstract
Damping ratio is one of the most important parameters considered in dynamic analysis of engineering structures. Determining and using of the damping ratio close to reality affects the accuracy of finite element analyses results. Within the scope of this paper, the variation of the displacements and stresses values obtained from the dynamic analysis of Artvin Deriner Arch Dam under different damping rates is investigated. The double curvature Deriner Arch Dam is the highest arch dam in Turkey, which continues to operate at full capacity. Time-history analysis are conducted on Deriner Arch Dam taking into account the 1999 Kocaeli earthquake acceleration record. Dynamic analyzes are repeated for the damping ratio of 1%, 5% and 10%. It has been observed that the variability in the damping ratio significantly affects the displacements and stresses values.
