Assessment of Risky Buildings according to the Regulation for Determination of Risky Buildings (RDRB 2019): The Case of Şanlıurfa

The majority of risky structures in Türkiye’s building stock were constructed before 2000. It has been discovered that buildings constructed before the year 2000 lack engineering services and cannot fulfill the requirements of current regulations. Buildings constructed before 2000 are clearly incapable of providing the required performance and ductility in the event of an earthquake. Therefore, based on the Regulation for Determination of Risky Buildings (RDRB 2019), field studies were conducted on existing buildings built before 2000 in the Siverek district of Şanlıurfa. a two-story reinforced concrete building designed in accordance with field study data was analyzed by following the risk analysis stages for low-rise reinforced concrete buildings in RDRB 2019. An elemental risk analysis was performed on 16 columns, which are vertical elements of the structure, and then a floor-based risk assessment was performed. As a consequence, it was concluded that the building designed in accordance with condition before 2000 was at risk.
