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 simulations including the dam-reservoir interaction. Afterwards, pseudo-dynamic testing was conducted on the specimen using three ground motions corresponding to different hazard levels. Lateral displacement and base shear demands were measured. The crack propagation at the base of the dam was monitored with the measurement of the crack widths and the base sliding displacements. After the pseudo-dynamic loading, a static pushover test was conducted to determine the reserve capacity of the test specimen. Despite major cracking at the base of the monolith, neither significant sliding nor a stability problem that might jeopardize the stability of the dam was observed.

Comparison of pseudo dynamic test results and numerical results of an RCC dam model Aldemir, Alper; Binici, Barış; Canbay, Erdem (2015-07-21) Inspired from the simplified single degree of freedom modeling approach used in the preliminary design of concrete gravity dams, a single degree of freedom 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. First, the single degree of freedom idealization of the dam section was validated in the first stage o...
Earthquake stresses and effective damping in concrete gravity dams Akpinar, Ugur; Binici, Barış; Arıcı, Yalın (2014-03-01) Dynamic analyses for a suite of ground of motions were conducted on concrete gravity dam sections to examine the earthquake induced stresses and effective damping. For this purpose, frequency domain methods that rigorously incorporate dam-reservoir-foundation interaction and time domain methods with approximate hydrodynamic foundation interaction effects were employed. The maximum principal tensile stresses and their distribution at the dam base, which are important parameters for concrete dam design, were ...
Quantitative comparison of 2D and 3D modeling for concrete gravity dams Evliya, Ekin Erdem; Arıcı, Yalın; Department of Civil Engineering (2014) Seismic behavior of gravity dams has long been evaluated and predicted using a representative 2D monolith for the dam. Formulated for the gravity dams built in wide-canyons, the assumption is nevertheless utilized extensively for almost all concrete dams due to the established procedures in 2D space as well as the expected computational costs of building a three dimensional model. A significant number of roller compacted concrete dams are being designed based on these procedures regardless of the valley dim...
Investigation of the relationship of seismic intensity measures and the accumulation of damage on concrete gravity dams using incremental dynamic analysis Soysal, BERAT FEYZA; Binici, Barış; Arıcı, Yalın (2016-04-25) Nonlinear analysis tools are gaining prominence for the design and evaluation of concrete gravity dams. The performance limits of concrete gravity dams within the framework of performance based design are challenging to determine in comparison to those used for the assessments based on linear elastic analyses. The uncertainty in quantifying the behavior of these systems and the strong dependence of the behavior on the ground motion play an important role. The purpose of the study is to quantify the damage l...
Seismic assessment of a monolithic RCC gravity dam including three dimensional dam-foundation-reservoir interaction Yilmazturk, Sema Melek; Arıcı, Yalın; Binici, Barış (2015-10-01) In this study, the seismic response of a tall roller compacted concrete gravity dam located in a highly seismic zone is investigated. The response of this monolithic RCC gravity dam is examined by conducting analyses including three dimensional dam-reservoir-foundation interaction. The effect of the foundation/structure moduli ratio, material damping, and bottom absorption and reservoir compressibility on the performance of the dam were investigated. Selection of an optimal downstream slope was discussed ba...
