A major earthquake with a magnitude Mw = 7.2 (ML = 6.7) occurred in the Eastern part of Turkey on October 23, 2011. The ground motion had a measured peak ground acceleration of 0.18×g. The earthquake damaged masonry and reinforced concrete structures ranging from minor cracking to total collapse. A 4-story reinforced concrete school building in Gedikbulak Village experienced total failure during this earthquake. This school building was a typical project (No: 10370) prepared by the Ministry of Education of Turkey and this typical project was widely being used for the construction of school buildings in various locations throughout Turkey. This paper explains the site observations of the Atılım University Reconnaissance Team carried out at the collapse site of the school building a few days after the main shock and detailed analysis with an emphasis on the reason for the failure of the school building. The analysis results indicated that the collapse happened due to the separation of the bottom of shear walls (in both x- and y-directions) from the foundation due to inadequate development and lap splice length of the plain reinforcing bars. Comments were made for existing school buildings to prevent any collapses in future earthquakes.

Teşekkür

The precious efforts of the members of the team, Prof. Dr. Eray Baran and Mr. Ferit Yılmaz (you will be remembered in our hearts), are very much appreciated. The local contacts in Van, Şemsettin Bakır, Necdet Telsaç, Kamuran Turgut, and Ercan Altunlı are also acknowledged.

23 Ekim 2011 tarihinde Türkiye'nin doğusunda Mw = 7,2 (ML = 6,7) büyüklüğünde bir deprem meydana gelmiştir. Yer hareketinin en yüksek yer ivmesi 0.18×g olarak ölçülmüştür. Deprem, yığma ve betonarme yapılarda küçük çatlaklardan tamamen göçmeye kadar değişen hasarlara neden olmuştur. Bu depremde, Gedikbulak Köyü'ndeki 4 katlı betonarme okul binası tamamen yıkılmıştır. Bu okul binası Türkiye Cumhuriyeti Milli Eğitim Bakanlığı tarafından hazırlanan tipik bir projedir (No: 10370) ve bu tipik proje Türkiye'nin çeşitli yerlerinde okul binalarının yapımında yaygın olarak kullanılmıştır. Bu makalede, Atılım Üniversitesi Keşif Takımının ana şoktan birkaç gün sonra okul binasının yıkıldığı yerde yaptığı saha gözlemleri ve okul binasının yıkılma nedenleri üzerinde durularak detaylı analizleri anlatılmaktadır. Analiz sonuçları göçmenin, düz donatı çubuklarının yetersiz kenetlenme ve bindirme boyu nedeniyle perde duvarların tabanının (hem x- hem de y- yönlerinde) temelden ayrılmasından kaynaklandığını göstermiştir. Yapılan inceleme ve analizler sonucunda benzer mevcut okul binalarının gelecekteki depremlerde yıkılmaması için önerilerde bulunulmuştur.
