Hımış Yapıların Deprem Performansının Bütüncül Analizi: 2023 Türkiye Deprem Sekansından Saha Bulguları

Öz

Şubat 2023 Türkiye deprem sekansı, ülkenin güneyindeki 11 ilde nüfus ve yapılı çevre üzerinde ağır etkiler yaratmıştır. Depremin bu yıkıcı sonuçlarının belgelenmesi amacıyla, Birleşik Krallık’ın Deprem Mühendisliği Saha Çalışmaları Ekibi (EEFIT), farklı dönemlerde deprem bölgesinde kapsamlı bir araştırma başlatmıştır. Bu çalışma kapsamda, bölgenin geleneksel konut mirasının karakteristik örnekleri arasında yer alan hımış yapılar, araştırma konusu olarak seçilmiştir. Çalışma kapsamında bu yapıların yapısal özellikleri ve deprem sonrası oluşan hasarları Coğrafi Bilgi Sistemlerinden (CBS) faydalanılarak belgelenmiştir. Bu makale, Kahramanmaraş, Malatya, Hatay ve Osmaniye'de yer alan toplam 189 hımış yapının deprem performanslarına ilişkin ön bulguları sunmaktadır. Çalışmada, bu yapıların maruz kaldığı üç önemli depreme (6 Şubat Mw 7.8 Pazarcık ve Mw 7.5 Elbistan depremleri; 20 Şubat Mw 6.3 Samandağ depremi) ait yer hareketi kayıtları ve ilgili mühendislik parametreleri kullanılarak gözlenen hasar durumları değerlendirilmektedir. Ayrıca, saha çalışmasında benimsenen CBS tabanlı yaklaşımın Türkiye bağlamındaki uygulanabilirliği ortaya konmakta ve benzer çalışmalara ışık tutması amaçlanmaktadır.

A Holistic Analysis Of The Seismic Performance Himiş Buildings: Field Evidence From The 2023 Türkiye Earthquake Sequence

Öz

The February 2023 Türkiye earthquake sequence, which struck 11 provinces spread across the southern part of the country, devastated the region’s built environment with lasting social impacts. In the aftermath of the events, the United Kingdom’s Earthquake Engineering Field Investigation Team (EEFIT) launched a comprehensive and longitudinal study within the earthquake-affected area. As part of this study, a two-phase post-disaster reconnaissance survey on the region’s traditional building stock, with specific emphasis on hımış typologies (hybrid structures with a masonry ground floor and timber-framed upper floors with infill or cladding), was conducted on a total of 189 hımış buildings in Kahramanmaraş, Malatya, Hatay and Osmaniye. The survey aimed to document the structural characteristics and conditions of hımış structures, and the extent and mechanisms of damage due to earthquakes, using a rapid and user-friendly protocol incorporating Geographic Information Systems (GIS). This article presents preliminary findings on the seismic performance of hımış structures in the region, and discusses these findings based on ground motion records and engineering parameters associated with three earthquakes (6 February Mw 7.8 Pazarcık and Mw 7.5 Elbistan earthquakes; 20 February Mw 6.3 Samandağ earthquake). In addition, it evaluates the applicability of the adopted GIS-based approach within the context of Türkiye, aiming to inform and guide similar future endeavours.
