In this study, dynamic response of Akköprü Dam under earthquake motions is analyzed and the permanent displacements are evaluated. Initially, the critical slip surface of the dam and the corresponding yield acceleration are determined by using the computer program SLOPE. Then, by employing the finite element program SAP2000, static analyses are performed to obtain the mean effective stresses which are used in the determination of dynamic material properties of the dam. Four different scenario earthquakes having a magnitude of 7 are used in the dynamic analyses. Two of those scenarios are taken from European Strong Motion Database and the others are generated by XS artificial earthquake generation program prepared by Erdik (1992). Dynamic analyses of the dam are carried out by the finite element program TELDYN. Permanent displacements of the critical slip surface are calculated by utilizing the Newmark method. Consequently, for an earthquake having a magnitude of M=7 and a peak ground acceleration of 0.20g, the maximum permanent displacement of the dam is found to be 15.90 cm. Furthermore, the permanent displacements of the dam are calculated under base motions having different peak ground acceleration values and it is observed that the rate of increase in the amount of permanent displacements is greater than the increase in the amount of peak ground accelerations.

Comparison of the overlapping lattice and thefinite element approaches for the prediction of the collapse state of concrete gravity dams
Soysal, Berat Feyza; Arıcı, Yalın; Binici, Barış; Tuncay, Kağan (null; 2017-10-11)
Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. In this context, the purpose of the study is to investigate the prediction capability of numerical tools in determining the collapse state of concrete gravity dams. The first tool used to this end is the classical finite element method with the smeared crac...
Uncertainty based analysis of seepage through earth-fill dams
Çalamak, Melih; Yanmaz, Ali Melih; Kentel Erdoğan, Elçin; Department of Civil Engineering (2014)
The steady-state and transient seepage through embankment dams are investigated considering the uncertainty of hydraulic conductivity and van Genuchten fitting parameters, α and n used for unsaturated flow modeling. A random number generation algorithm producing random values for these parameters is coupled with a finite element software, SEEP/W to analyze seepage through earth-fill dams. Monte Carlo simulation is adopted for stochastic seepage analyses. The variability effects of the random parameters on s...
Experimental evaluation of geomembrane / geotextile interface as base isolating system
Taheri Bonab, Amin; Gülerce, Zeynep; Kalpakcı, Volkan; Department of Civil Engineering (2016)
The objective of this study is to evaluate the effect of the composite liner seismic isolation system on the seismic response of small-to-moderate height structures. For this purpose, a building model with the natural frequency of 3.13 Hz (representing 3-4 story structures) was tested with and without the addition of composite liner system using the shaking table test set-up by employing harmonic and modified/ scaled ground motions. Experiment results showed that the composite liner seismic isolation system...
Effect of shear walls on the behavior of reinforced concrete buildings under earthquake loading
Çömlekoğlu, Hakkı Gürhan; Burak Bakır, Burcu; Department of Civil Engineering (2009)
An analytical study was performed to evaluate the effect of shear wall ratio on the dynamic behavior of mid-rise reinforced concrete structures. The primary aim of this study is to examine the influence of shear wall area to floor area ratio on the dynamic performance of a building. Besides, the effect of shear wall configuration and area of existing columns on the seismic performance of the buildings were also investigated. For this purpose, twenty four mid-rise building models that have five and eight sto...
Tsunami hydrodynamics in coastal zones
Özer, Ceren; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2012)
This study analyzes the parameter “hydrodynamic demand” that is also defined by the square of Froude Number representing the damage of tsunami waves on structures and coastlines, and other hydrodynamic parameters, i.e., the distribution of instantaneous flow depths, runup values and the direction of maximum currents, occurred during tsunami inundation by using advanced numerical modeling. The analyses are performed on regular-shaped basins with different bottom slopes and real-shaped topographies using diff...
