Farklı Kat Seviyelerine Sahip Betonarme Binalarda Çarpma Etkilerinin İncelenmesi

Abstract

Betonarme binaların deprem sırasında serbest bir şekilde yer değiştirmeleri gerekir. Bununla birlikte, betonarme binaların bitişik nizam olarak inşa edilmesi, binaların serbest yer değiştirmesini kısıtlar. Özellikle farklı kat seviyelerinde bitişik olarak inşa edilen binalarda ciddi gevrek hasarlar meydana gelmektedir. Bu çalışma, doğrusal olmayan zaman geçmişi analizi kullanarak bitişik betonarme binalar arasındaki çarpışma etkisini araştırmaktadır. Bu amaçla, aralarında boşluk bulunmayan iki betonarme çerçeve tasarlanmıştır. Betonarme çerçeveler tek katlı ve üç katlı yapılar olarak tasarlanmıştır. Daha sonra, bu iki bina arasındaki çarpışma etkisini göstermek için doğrusal olmayan zaman geçmişi analizleri yapılmıştır. Ayrıca, yetersiz boşluk mesafesi nedeniyle deprem sırasında kolonlarda oluşabilecek ek kesme kuvvetleri belirlenmiştir. Analizler sonucunda, yetersiz derz mesafesi nedeniyle meydana gelen çarpışma etkisi ile kolonlara etki eden kesme kuvvetinin yaklaşık 3-4 kat arttığı belirlenmiştir.

Investigation of Pounding Effects in Reinforced Concrete Buildings for Different Story Levels

Abstract

Reinforced concrete buildings should be able to move freely during an earthquake. However, the construction of reinforced concrete (RC) buildings as adjacent configuration restricts the free displacement of buildings. Serious brittle damage occurs especially in buildings constructed adjacently at different story levels. This study investigates the pounding effect between adjacent reinforced concrete buildings using nonlinear time history analysis. For this purpose, two reinforced concrete buildings were designed without any gap between them. Reinforced concrete frames have been designed as single-story and three-story structures. Then, nonlinear time-history analyses were performed to show the pounding effect between these two buildings. Furthermore, the additional shear forces that could occur in the columns during an earthquake due to insufficient gap distance were determined. The analyses revealed that the pounding effect caused by insufficient gap distance increase shear forces applied to columns approximately 3-4 times.
