load carrying system characteristics of existing turkish rc building stock

seismic performance and loss assessment studies for stock of buildings are generally based on representative models due to extremely large number of vulnerable buildings. the main problem is the proper reflection of the building stock characteristics well enough by limited number of representative models. this study aims to provide statistical information of structural parameters of turkish building stock for proper modeling using a detailed inventory study including 475 low and mid-rise rc building with 40351 columns and 3128 beams for member properties. thirty-five different parameters of existing low and mid-rise turkish rc building stock are investigated. an example application is given to express use of given statistical information. the outcomes of the current study and previous studies are compared. the comparison shows that the previous studies have guidance for limited number of parameters while the current study provides considerably wide variety of structural and member parameters for proper modeling.
