Evaluation of Structural Properties of Existing Turkish RC Building Stock

The huge number of structures in which the major portion of the population resides will be seriously damaged if there is an earthquake on a medium or a large scale. For this reason, it has become a necessity to determine the structural characteristics in order to assess the seismic performances of existing RC buildings. However, the enormous size of the building stock to be assessed is the biggest problem for this evaluation. Therefore, it is necessary to make evaluations on all stock by making generalizations over the sample buildings for reflection of building stock. From this perspective, the building models used to reflect the exact building stock is of great importance. This study aims to generate statistics about structural properties of Turkish RC building stock using a detailed archive investigation. The inventory data set contains 8850 beams, 26,963 columns and 2311 shear walls from 506 existing residential buildings for comprehensive assessment. In this study, important structural parameters which are effective on the seismic response of existing RC building stock are investigated for proper modeling. The buildings are subgrouped according to embedded and emergent beam systems, absence and presence of shear walls and number of storeys. The statistical information such as average values, standard deviation and coefficient of variation has been investigated for the considered parameters. The findings of the present study were compared with past studies depending on the average values of parameters. The comparison emphasizes that the values of some parameters may be affected by construction date and number of storeys.
