In this study, structural vulnerability of reinforced concrete frame structures by considering the country&ndash / specific characteristics is investigated to manage the earthquake risk and to develop strategies for disaster mitigation. Low&ndash / rise and mid&ndash / rise reinforced concrete structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragility&ndash / based assessment. The seismic design of 3, 5, 7 and 9&ndash / story reinforced concrete frame structures are carried out according to the current earthquake codes and two dimensional analytical models are formed accordingly. The uncertainty in material variability is taken into account in the formation of structural simulations. Frame structures are categorized as poor, typical or superior according to the specific characteristics of construction practice and the observed seismic performance after major earthquakes in Turkey. The demand statistics in terms of maximum interstory drift ratio are obtained for different sets of ground motion records. The capacity is determined in terms of limit states and the corresponding fragility curves are obtained from the probability of exceeding each limit state for different levels of ground shaking. The results are promising in the sense that the inherent structural deficiencies are reflected in the final fragility functions.
Consequently, this study provides a reliable fragility&ndash / based database for earthquake damage and loss estimation of reinforced concrete building stock in urban areas of Turkey.
