Sokaktan Tarama Yöntemiyle Binaların Bölgesel Deprem Risk Dağılımının Belirlenmesi: Bilecik İli Örneği

Depremler dünyada olduğu gibi ülkemizde de göz ardı edilemeyecek bir doğa olayıdır. Ülkemizin deprem kuşağında yer alması sebebiyle bu hususlardaki araştırmalar son yıllarda artış göstermektedir. Bu çalışmada Bilecik ilinin merkez mahallelerinde, depremin betonarme ve yığma/karma binalar üzerinde oluşturabileceği etkiler Sokaktan Tarama Yöntemiyle ele alınmıştır. Bu kapsamda Bilecik ili merkez mahalleleri (Bahçelievler, Beşiktaş, Cumhuriyet, Ertuğrulgazi, Gazipaşa, Hürriyet, İsmetpaşa, İstiklal) üzerinde bulunan 1021 betonarme ve 370 yığma/karma olmak üzere toplam 1391 adet bina incelenmiştir. Her bir mahallenin betonarme ve yığma/karma binalar için ayrı ayrı ortalama Bina Deprem Puanları hesaplanmıştır. Betonarme binalar açısından Bahçelievler, Cumhuriyet, Gazipaşa, İsmetpaşa ve İstiklal mahalleleri Bina Deprem Güvenirliği açısından Düşük Riskli iken Beşiktaş, Ertuğrulgazi ve Hürriyet mahallelerinin Bina Deprem Güvenirliği açısından Güvenli olduğu tespit edilmiştir. Yığma/karma binalar açısından tüm mahalleler Bina Deprem Güvenirliği açısından Güvenli bulunmuştur.

Determination of Regional Soil Structure Earthquake Risk Distribution of Buildings by Street Survey Method: The Sample of Bilecik Province

Earthquake is a natural phenomenon that cannot be ignored in Turkey as in the world. Since Turkey is located in the earthquake zone, research on these issues has increased in recent years in Turkey. In this study, the effects of the earthquake on the reinforced concrete and masonry/mixed buildings in the central neighborhoods of Bilecik province were examined by the Street Survey Method. In this context, a total of 1391 buildings including 1021 reinforced concrete and 370 masonry/mixed buildings on the central districts of Bilecik were examined. The average building earthquake scores for the reinforced concrete and masonry/mixed buildings of each neighborhood were calculated. In terms of reinforced concrete buildings, Bahçelievler, Cumhuriyet, Gazipaşa, Ismetpaşa and Istiklal neighborhoods were found to be at Low Risk in terms of Building Earthquake Safety, while Beşiktaş, Ertuğrulgazi and Hürriyet neighborhoods were found to be Safe in terms of Building Earthquake Safety. All masonry/mixed buildings were found to be Safe in terms of Building Earthquake Safety.
