A statistical study on geometrical properties of turkish reinforced concrete building stock

Vulnerability assessment of building stocks is one of the major concerns in earthquake prone areas such as Turkey. Recent earthquakes have shown that identification of seismic hazard, reliable estimation of seismic vulnerability, and proactive interventions are of prime importance in terms of seismic risk mitigation. The success of the seismic risk assessment relies on the accuracy of its components particularly on estimation of fragility of buildings. To achieve this goal, the earthquake loss models should reflect the local characteristics of building stocks in a realistic way. In this study, a statistical survey is carried out on the general structural properties of Turkish reinforced concrete (RC) building stock using the building inventories of Düzce city as well as Zeytinburnu, Küçükçekmece, and Bakırköy districts of İstanbul. The geometrical properties studied in the building databases are story height, floor plan dimensions, number of continuous frames, span lengths, and column dimension and orientation. This study presents the statistical results in terms of mean and standard deviation of examined geometrical properties
