This paper focuses on the seismic fragility assessment of typical low-rise and mid-rise reinforced concrete (RC) buildings in Turkey by considering Duzce Damage database, which was compiled after the two devastating earthquakes in 1999 that affected the Marmara region. A set of fragility curves is developed by making use of the building characteristics in the database. The generated fragility curve set is referred as "reference" since it forms the basis of a parametric study. Then the influence of sampling techniques, sample size, type of hysteresis model and limit state definitions on the fragility curves is investigated. The results revealed that the uncertainty in capacity and degradation characteristics have a significant influence whereas the other investigated parameters do not seem to have an important role on the final fragility functions. In the last part of the study, the damage observed in Duzce buildings after 1999 earthquakes is estimated by using the generated fragility curves for low-rise and mid-rise RC frame buildings. Estimated damage distributions seem to be comparable with the actual damage data.

Fragility based assessment of lowrise and midrise reinforced concrete frame buildings in turkey using Düzce damage database Özün, Ahsen; Erberik, Murat Altuğ; Department of Civil Engineering (2007) In this study, the seismic fragility assessment of low-rise and mid-rise reinforced concrete frame buildings which constitute approximately 75 % of the total building stock in Turkey is investigated to quantify the earthquake risk. The inventory used in this study is selected from Düzce damage database which was compiled after the devastating 1999 earthquakes in the Marmara region. These buildings are not designed according to the current code regulations and the supervision in the construction phase is not...
Assessment of seismic fragility curves for low- and mid-rise reinforced concrete frame buildings using Duzce field database Erberik, Murat Altuğ (2005-06-01) This paper focuses on the generation of fragility curves for low-rise and mid-rise reinforced concrete frame buildings, which constitute approximately 75% of the total building stock in Turkey and which are generally occupied for residential purposes. These buildings, which suffered extensive damage after recent earthquakes, are not designed according to the current code regulations and the supervision in the construction phase is not adequate. Hence the buildings possess many deficiencies like irregulariti...
Structural rehabilitation of damaged RC buildings after the 1 october 1995 Dinar earthquake Wasti, ST; Sucuoğlu, Haluk; Utku, M (2001-04-01) This paper contains technical information related to the Dinar project for the rehabilitation of moderately damaged reinforced concrete buildings after the 1 October 1995 Dinar earthquake. The structural appraisal of the damaged buildings, analytical studies leading to decisions regarding structural rehabilitation or demolition, the supervision on site of the rehabilitation and the overall coordination of the project was entrusted to the Middle East Technical University Earthquake Engineering Research Cente...
Fragility based assessment of lowrise and midrise reinforced concrete frame buildings in Turkey Ay, Bekir Özer; Erberik, Murat Altuğ; Department of Civil Engineering (2006) In this study, structural vulnerability of reinforced concrete frame structures by considering the countryspecific characteristics is investigated to manage the earthquake risk and to develop strategies for disaster mitigation. Lowrise and midrise reinforced concrete structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragilitybased assessment. The seismic design of 3, 5, 7 and 9story reinforced concrete frame structures are carried out according to the ...
Probabilistic methods for the estimation of potential seismic damage: Application to reinforced concrete buildings in Turkey Askan Gündoğan, Ayşegül; Yücemen, Mehmet Semih (2010-01-01) Three probabilistic methods, for the prediction of potential seismic damage to low and mid-rise reinforced concrete buildings in Turkey, are presented As the first method. "best estimate" damage probability matrices for each seismic zone are developed by combining expert opinion and the damage statistics compiled from the recent earthquakes occurred in Turkey. Second method involves a reliability-based model, which treats the earthquake force and seismic resistance as random variables This model expresses p...
