Fragility Based Assessment of the Structural Deficiencies in Turkish RC Frame Structures

2006-09-08
Low–rise and mid–rise reinforced concrete (RC) structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragility–based assessment. The seismic design of three, five, seven and nine story RC 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 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 inter–story 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.

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...
Fragility-based assessment of typical mid-rise and low-rise RC buildings in Turkey
Erberik, Murat Altuğ (2008-05-01)
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 ...
Analysis and design of FRP composites for seismic retrofit of infill walls in reinforced concrete frames
Binici, Barış; Ozcelik, Ramazan (Elsevier BV, 2007-01-01)
There is an urgent need to retrofit deficient mid-rise reinforced concrete (RC) frame buildings in Turkey. For this purpose, an efficient FRP retrofit scheme has been developed previously, in which hollow clay brick infill walls can be utilized as lateral load resisting elements after retrofitting. The main premise of this practical retrofit scheme was to limit inter-storey deformations by FRP strengthened infill walls that are integrated to the boundary frame members by means of FRP anchors. Based on the a...
Seismic strengthening of reinforced concrete frames by precast concrete panels
BARAN, MEHMET; Susoy, M.; Okuyucu, D.; Tankut, T. (Thomas Telford Ltd., 2011-05-01)
An innovative occupant-friendly retrofitting technique has been developed for reinforced concrete (RC)-framed structures which constitute the major portion of the existing building stock. The idea is to convert the existing hollow brick infill wall into a load-carrying system acting as a cast-in-place concrete shear wall by reinforcing it with relatively thin high-strength precast concrete panels epoxy bonded to the plastered infill wall and epoxy connected to the frame members. In this study, results of 11...
Multistage seismic assessment methods for existing reinforced concrete buildings and their applicability for retrofitting cost estimation
Doğan, Onur; Yücemen, Mehmet Semih; Koçyiğit, Ali; Department of Earthquake Studies (2013)
When the huge building stock in Turkey is considered, it is practically impossible to carry out detailed structural analyses for all of the buildings. In order to cope with the seismic safety evaluation of a large number of existing buildings, it is necessary to use simplified techniques, which can predict the seismic vulnerability of the existing buildings in a relatively short time. The comprehensive structural data compiled for the 48 different reinforced concrete buildings contain full information on th...
