Özet:

 This study aims to investigate the effects of the February 6, 2023 Kahramanmaraş Pazarcık Mw7.7 and Kahramanmaraş Elbistan Mw7.6 earthquakes on the affected building stock. For this purpose, Hatay, one of the most affected provinces by these earthquakes, was selected as the pilot province. Accordingly, a four-story reinforced concrete frame, where all seismic loads are carried by the frames, was considered to represent the buildings. The structural elements columns and beams forming the frame were designed in accordance with the 1968, 1975, 1998, and 2007 Earthquake Regulations, as well as the 1975, 1984, and 2000 reinforced concrete standards TS500. Subsequently, numerical models of these frames were created. The designed buildings were defined at 11 different locations in Hatay province. The different locations selected in Hatay province were chosen in the same positions as the TADAS stations affiliated with AFAD to avoid the process of transferring recorded ground motions between locations. A total of 211 records East-West and North-South Horizontal Components obtained from accelerometers were individually applied, while the recorded vertical accelerations were considered in the numerical analyses. Nonlinear time history analyses were performed considering the 11 different positions and directions for each building type. Within the scope of this study, seismic performances were obtained for a total of 88 different building designs and earthquake scenarios. The results indicate that medium-rise reinforced concrete frame buildings designed in accordance with the design and earthquake regulations used in the past years in our country are inadequate in terms of seismic resistance during earthquakes centered in Kahramanmaraş and the collapse cannot be prevented.

 Bu çalışma, 6 Şubat 2023 Kahramanmaraş Pazarcık Mw7.7 ve Kahramanmaraş Elbistan Mw7.6 depremlerinin, depremlerden etkilenen yapı stokunun üzerindeki etkilerini incelemeyi amaçlamıştır. Bu maksatla, depremlerden en çok etkilenen illerden olan Hatay pilot il olarak seçilmiştir. Bu doğrultuda, deprem yüklerinin tamamının çerçevelerle taşındığı dört katlı bir betonarme düzlem çerçeve, binaları temsilen ele alınmış olup, çerçeveyi oluşturan yapısal elemanlar kolon ve kirişler 1968, 1975, 1998 ve 2007 Deprem Yönetmelikleri ile 1975, 1984 ve 2000 betonarme standartlarına TS500 uygun olarak tasarlanmıştır. Ardından; bu çerçevelerin sayısal modelleri oluşturulmuştur. Tasarlanan binalar Hatay ilindeki 11 farklı konumda tanımlanmıştır. Hatay ilinde seçilen farklı konumlar, kaydedilen yer hareketlerinin konumlar arası taşıma işlemine tabi tutulmaması için AFADa bağlı TADAS istasyonlarıyla aynı pozisyonda seçilmiştir. İvmeölçerlerden alınan 211 adet kayıt Doğu-Batı ve Kuzey-Güney Yatay Bileşenleri ayrı ayrı uygulanırken kaydedilen düşey ivmelerde numerik analizlerde dikkate alınmıştır. Her bir bina tipi için seçilen 11 farklı konum ve doğrultu dikkate alınarak, doğrusal olmayan zaman tanım alanında analizler yapılmıştır. Çalışma kapsamında toplam 88 adet farklı bina tasarımı ve deprem senaryosu için, sismik performanslar elde edilmiştir. Sonuçlar incelendiğinde, ülkemizde geçmiş yıllarda kullanılmış olan tasarım ve deprem yönetmeliklerine uygun olarak tasarlanmış betonarme çerçeveli orta yükseklikteki binaların sismik dayanımlarının Kahramanmaraş merkezli depremlerde yetersiz kaldığını ve göçme durumunun önlenmesinin mümkün olmadığını ortaya koymuştur.
