In Turkey, where three significant fault lines locate, earthquakes with a magnitude greater than 6.5 happen in every 10 years (Azak et al., 2014). In this sense, to estimate damage on building stock and fatalities accurately, real characteristics of Turkish building stock (TBS) should be known well. Gathering TBS portfolio is previously studied but these studies have focused on relatively smaller areas or have been outdated or both. This study made an comprehensive search on available data sources and detailed investigation on two sources: 2000 Building Census and Building Occupancy Permit Statistics disseminated by Turkish Statistical Institute. Then, the available databases including TBS is harmonized to generate a consistent and complete building stock data for its use in earthquake loss estimation studies. The attributes, which are considered as primary earthquake risk parameters, are the location (in province-scale resolution for İstanbul and region-scale and city-scale resolution for all other places in Turkey), the construction year, the function, the structural system, the number of stories, the material of infill walls, the number of dwelling units and total produced floor area. This study examined 9394841 buildings in total and presented the distribution of TBS characteristics with respect to the parameters and their relation. To conclude, this study presents gathering of the harmonized up-to-date Turkish building stock portfolio and investigations on building characteristics. The aim of this study is to provide a reference building database for Turkey and corresponding statistics to be used for earthquake loss es timation studies.

Evaluation of Changing Building Characteristics in Turkey Ay, Bekir Özer; Erberik, Murat Altuğ (2016-09-23) Seismic risk combines earthquake induced hazard with structural response and determines loss that is equaled or exceeded over some time period. In this sense, it is of prime importance to utilize proper earthquake loss models that are able to consider local characteristics of building stock in a realistic way. The aim of this study is to compile changing characteristics of Turkish buildings that is believed to be necessary to develop representative models for loss estimations. Accordingly, a statistical sur...
A critical examination of near-field accelerograms from the sea of Marmara region earthquakes Akkar, S; Gulkan, P (Seismological Society of America (SSA), 2002-02-01) In 1999, Turkey was struck by two major earthquakes that occurred 86 days apart on the North Anatolian Fault system. Both earthquakes had right-lateral strike-slip mechanisms with moment magnitudes greater than 7. The number of strong-motion records obtained from the Kocaeli earthquake (17 August 1999, M-w 7.4) was 34. The second event, designated as the Bolu-Duzce earthquake (12 November 1999, M-w 7.2), triggered 20 instruments. Among the records that we have from these earthquakes, seven are from near-sou...
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...
Seismic risk assessment of gravity load designed reinforced concrete frames subjected to mid-America ground motions Çelik, Ozan Cem (American Society of Civil Engineers (ASCE), 2009-03-24) The infrequent nature of earthquakes in the Central and Eastern United States (CEUS), and the fact that none with intensity comparable to the New Madrid sequence of 1811-12 has occurred in the past century, have caused the earthquake hazard in the CEUS to be neglected until quite recently. The performance of reinforced concrete (RC) frames in the CEUS may be deficient if they are subjected to earthquakes that are believed to be plausible in the New Madrid Seismic Zone (NMSZ). This study presents a set of pr...
A comparative study on the actual and estimated seismic response of Kiralkizi Dam in Turkey Çetin, Kemal Önder; Batmaz, S; Karabiber, S (Informa UK Limited, 2005-07-01) 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 (i...
