Damage Assessment of Buildings in Adıyaman-Gölbaşı after Kahramanmaras Earthquakes (6 February 2023)

Abstract

According to the data of Disaster and Emergency Management Presidency (AFAD), on 6 February 2023, at 4.17 and 13.24 (at Turkish time), earthquakes with magnitudes of 7.7 and 7.6 (Mw) occurred with epicentres in Pazarcık (Kahramanmaraş) and Elbistan (Kahramanmaraş), respectively. These earthquakes affected 11 provinces of Turkey and were recorded as the most destructive earthquakes in the last century. Adıyaman-Gölbaşı was also highly affected by these earthquakes, which caused loss of life and property, and numerous buildings were destroyed and damaged. In this study, the situation of Gölbaşı district of Adıyaman province after the earthquakes was discussed. The current situation in the city as of May has been documented. Damaged reinforced concrete structures were examined on-site in terms of structural irregularities, application methods and material properties and the causes of the damages were evaluated. It was determined that there were major damages especially in the settlement areas close to the lake. The results of the study clearly reveal that natural disasters that may occur are directly related not only to structural systems but also to ground conditions.
