Abstract
According to the Disaster and Emergency Management Presidency (AFAD), two medium-sized earthquakes with a moment magnitude of 5.6 occurred on 25 and 28 March 2004. After these earthquakes, damage occurred in the local settlement areas, especially in buildings that did not receive engineering service, and 10 people lost their lives. Due to the loss of life and property, many different researchers investigated this earthquake in detail from different scientific perspectives. It is aimed that the strong ground motion records are examined within the framework of the Turkish Building Earthquake Code (TBEC-2018) in this study. The response spectra have been interpreted according to TBEC-2018 regulation by using Tercan-Erzincan acceleration records from AFAD strong ground motion stations with this motivation. The results show that the values revealed in the 25-28 March 2004 earthquakes are incomparably lower than the predicted values according to TBEC-2018. These values, which are quite below what was predicted by both TBEC-2018 and the old earthquake regulations, confirm that the damages after the Aşkale earthquakes are related to the building features that have not received engineering service.
