Kiralkizi Dam, a 120 in high earthfill dam located in Diyarbakir city, Turkey, was shaken by a moment magnitude, M-w = 4.6 earthquake at an epicentral distance of 8 km, on December 24, 2000, at 13:31 local time. The seismic response of the dam was assessed by using spectral ratios between (i) available crest and foundation records (C/F), (ii) horizontal and vertical components of the recorded motions (H/V), (iii) by performing 2 dimensional finite difference-based seismic response analyses (Flac-2D), and (iv) 1D elastic shear beam solutions. First mode of vibration of the dam in the transverse direction by all four methods were estimated in the range of 0.55 to 0.62 second. Similar close agreement was not observed in higher modal periods estimated by H/V technique as compared to the predictions by C/F, Flac-2D, shear beam analysis techniques. Thus, H/V technique was concluded to be useful for the estimation of the fundamental resonance frequency of a soil structure, but not for its higher harmonics as consistent with available limited literature. In the longitudinal direction, natural period of the dam was estimated as 0.28 and 0.82 second by H/V and C/F techniques, respectively. Such disagreement was explained by (i) differences in the definitions of the estimated periods, (ii) internal impedance contrast of the dam, (iii) contributions of 3D valley effects. Single seismometer record obtained from crest level was found to be inadequate for reliably assessing the response of a dam in the longitudinal direction, and it is recommended to install multiple seismometers both within dambody and the abutments. Last but not least, the results of these analyses were further compared by available accelograms recorded at three earthfill and rockfill dams from Japan. In general, it was concluded that the seismic response of Kiralkizi Dam is comparable and within the prediction ranges of available analyses methods and is consistent with the expected response of a dam this height.


An evaluation of the strong ground motion recorded during the May 1, 2003 Bingol Turkey, earthquake
Akkar, S; Boore, DM; Gulkan, P (Informa UK Limited, 2005-03-01)
An important record of ground motion from a M6.4 earthquake occurring on May 1, 2003, at epicentral and fault distances of about 12 and 9 km, respectively, was obtained at a station near the city of Bingol, Turkey. The maximum peak ground values of 0.55 g and 36 cm/s are among the largest ground-motion amplitudes recorded in Turkey. From simulations and comparisons with ground motions from other earthquakes of comparable magnitude, we conclude that the ground motion over a range of frequencies is unusually ...
An evaluation of Guldurcek dam response during 6 June 2000 orta earthquake
Ozkan, MY; Ozyazicioglu, M; Aksar, UD (Elsevier BV, 2006-05-01)
Guldurcek dam located in the central Anatolia was subjected to longitudinal cracks of not wider than 2 cm during 6 June 2000 Orta earthquake. In this study, a brief account of the 6 June 2000 Orta earthquake is given and the results of dynamic FEM analyses of the dam, incorporating the non-linear soil properties under six selected base motions, are presented. Of the six base motions used in the analyses, three have been modified from the European strong motion database having similar ground motion parameter...
An evaluation of Surgu Dam response during 5 May 1986 earthquake
Ozkan, MY; Erdik, M; Tuncer, MA; Yilmaz, C (Elsevier BV, 1996-01-01)
Surgu Dam, located in southeast Turkey was subjected to longitudinal cracks on the dam crest and simultaneous settlement on the upstream part of the day, during 5 May 1986 Malatya Earthquake. In the following, a brief account of the 5 May 1986 earthquake and the damage occurred in the dam is reviewed, and the results of a dynamic finite element analysis incorporating the non-linear soil properties are presented. It is observed that, a Newmark type permanent displacement analysis carried out under simulated ...
Analysis of a highway embankment failure associated with the 1999 Duzce, Turkey earthquake
Bakır, Bahadır Sadık (Elsevier BV, 2005-04-01)
An embankment slope on a major highway totally collapsed during 12 November 1999 Duzce earthquake (M-w = 7.1) due to the intense near field ground motion. The slope had performed satisfactorily, without even minor deformations or cracks, during the Izmit earthquake (M-w = 7.4), another major event that occurred 3 months before and was far field. Predominantly coarse-grained fill of the embankment exhibited typical non-brittle behavior during laboratory tests, implying that the prefailure shear strength woul...
A comparative study of European earthquake loss estimation tools for a scenario in Istanbul
Strasser, F. O.; Bommer, J. J.; ŞEŞETYAN, KARİN; ERDİK, MUSTAFA ÖZDER; Cagnan, Z.; Irizarry, J.; Goula, X.; Lucantoni, A.; Sabetta, F.; Bal, I. E.; Crowley, H.; Lindholm, C. (Informa UK Limited, 2008-01-01)
A damage estimation exercise has been carried out using the building stock inventory and population database of the Istanbul Metropolitan Municipality and selected European earthquake loss estimation packages: KOERILOSS, SELENA, ESCENARIS, SIGE, and DBELA. The input ground-motions, common to all models, correspond to a "credible worst case scenario'' involving the rupture of the four segments of the Main Marmara Fault closest to Istanbul in a M-w 7.5 earthquake.
