The seismic performance of the tallest roller-compacted concrete gravity dam in Turkey is investigated in this study. For this purpose, two- and three-dimensional nonlinear dynamic finite element analyses were conducted to investigate the expected damage under simulated ground motions. Based on the results of finite element simulations, it was found that the three-dimensional behaviour of the dam is substantially different from the idealised two-dimensional monolith behaviour, even for a dam having monoliths separated with transverse joints. In addition, it was determined that in order to limit the cracking at the base of the dam, higher strength grout-enriched concrete must be used on the upstream and downstream faces. This study demonstrates the importance of three-dimensional modelling for gravity dams built in relatively narrow valleys along with the significance of the modelling of the nonlinear response for seismic performance assessment.

Comparison of loads in Turkish earthquake code with those computed statistically Firat, Fatih K.; Yücemen, Mehmet Semih (2015-05-01) In this study, earthquake loads are investigated statistically and compared with the nominal earthquake loads calculated according to the Turkish Earthquake Code, namely: "Specifications for Structures to be Built in Earthquake Areas". For this purpose, the "actual" mean load values estimated from statistical methods and the nominal load values computed according the Seismic Code are compared, with respect to some variations in the basic parameters, such as the importance factor, building height, site coeff...
Pseudo-dynamic testing of a concrete gravity dam Aldemir, Alper; Binici, Barış; Arıcı, Yalın; Kurç, Özgür; Canbay, Erdem (2015-09-01) Inspired from the simplified single degree of freedom modeling approach used in the preliminary design of concrete gravity dams, a pseudo-dynamic testing method was devised for the seismic testing of a concrete gravity dam section. The test specimen was a 1/75 scaled section of the 120-m-high monolith of the Melen Dam, one of the highest concrete gravity dams to be built in Turkey. The single degree of freedom idealization of the dam section was validated in the first stage of the study using numerical simu...
Comparison of the Overlapping Lattice and the Finite Element Approaches for the Prediction of the Collapse State of Concrete Gravity Dams Soysal Albostan, Berat Feyza; Arıcı, Yalın; Binici, Barış; Tuncay, Kağan (2017-10-13) 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...
Analysis Methods for the Investigation of the Seismic Response of Concrete Dams Aldemir, Alper; Yilmazturk, Sema Melek; Yucel, Ali Riza; Binici, Barış; Arıcı, Yalın; Akman, Altug (2015-01-01) The consideratiOn of the dam-foundation-reservoir interaction is extremely important for estimating the seismic response of concrete gravity dams. Moreover, nonlinear analysis may be required for determining the possible risk associated with dams. In order to address these issues, DSI recently published the "Guidelines for Seismic Design of Concrete Dams". Authors who have contributed to the preparation of this document provide a perspective on the seismic safety/design of concrete dams and structural analy...
Comparison of mean site-specific response spectra in Turkey with the design spectra of AASHTO Mestav Sarıca, Gizem; Askan Gündoğan, Ayşegül; Department of Civil Engineering (2014) Seismic design of bridges is a significant problem for all seismically-active countries including Turkey which has gone through recent destructive earthquakes. Bridges are important elements of transportation and their robustness is important in the aftermath of major earthquakes. Turkish engineers currently employ a modified version of AASHTO (American Association of State Highway and Transportation Officials) LFD Design Specifications for bridge design. Within the scope of a national project (TÜBİTAK 110G...
