Abstract

Türkiye nüfusunun yaklaşık% 30'u kırsal kesimde yaşıyor ve donatısız/betonarme olmayan yığma bina (URM) olarak adlandırılan yapılarda yaşamaktadırlar. Bu tip binalar, ahşap karkaslı kerpiç yapılar, ahşap destekli yığma-kerpiç yapılar ve betonarme lentolarla desteklenen tuğla ve briket yığma yapılardan oluşmaktadır. Yığma yapıların yapımı, tuğla ve yığma gibi yapı malzemelerinin kolay bulunabilirliği nedeniyle kolay ve düşük maliyetli olduğundan yaygın olarak rastlanmaktadır.
Ancak bu binalar, özellikle pek çok açıdan kötü inşa edilmiş yığma binalar, son depremlerde çok kötü performans göstermiş, can ve mal kaybına neden olmuştur.
Bu nedenle bu yapıların iyileştirilmesi veya güçlendirilmesi talebinin can ve mal kurtarılması açısından çok önemli olduğu ve bu amaçla sismik araştırma ve değerlendirmenin gerekli olduğu bir kez daha görülmüştür. Bu çalışmada esnek diyaframlı tuğla yığma yapının deprem davranışı SAP200 Sonlu eleman programı kullanılarak değerlendirilmiştir. Düz ve hatıl olmak üzere iki tip yığma bina modellenmiştir. Yer değiştirme, Taban kesme ve Gerilme verileri Analiz sonuçları elde edilmiş ve iki model için karşılaştırılmıştır.

Seismic Behavior Evaluation of URM Building in Rural Area

Abstract

Approximately 30% of Turkey's population lives in rural areas and they are seated in structures, which called unreinforced masonry building (URM). These types of buildings consist of mudbrick structures with wooden carcasses, masonry-adobe structures with wooden supports, and brick and briquette masonry structures supported by reinforced concrete lintels. The construction of masonry structures is easy and low cost because of the easy availability of building materials such as brick and masonry, so it is frequently preferred.
However, these buildings, especially poorly constructed masonry buildings in many respects, have performed very badly in recent earthquakes, causing loss of life and property.
For this reason, it was once again seen that the demand for the improvement or strengthening of these structures is very important in terms of saving life and property, and that seismic research and evaluation are necessary for this purpose. İn this study, the earthquake behavior of the brick masonry structure with a flexible diaphragm is evaluated using SAP200 Finite element program. Two types of masonry buildings were modeled which are plain and bond beams. Displacement, Base shear, and Stress data The analysis results are obtained and compared for two models.
