Investigation of New Generation Precast Concrete Panel Applications as Reinforcement Technique

Öz

In this study, a strengthening method that can be applied without building occupants having to leave the building was investigated.  For this purpose, a reinforced concrete frame, which is 1/3 scaled, low-strengthened against earthquake, has two-story and single span unreinforced brick infilling wall, has been produced with failures frequently seen especially in concrete buildings of our country  as reference sample. Moreover, strengthening three reinforced concrete  infilled frame wall having same features with reference sample by new diagonal concrete panels which are precast, high strengths in different shapes, their behaviors under reversible-repeatable horizontal loading simulating earthquake effect have been tested. Results of the experiment have been compared with the analytic study used in SAP2000 v17.3 and it has been observed that applied technique has increased the energy dissipation capacity of test elements and improved the earthquake behaviors.

GÜÇLENDİRME TEKNİĞİ OLARAK YENİ NESİL ÖN ÜRETİMLİ BETON PANEL UYGULAMASININ ARAŞTIRILMASI

Öz

Bu çalışmada, bina sakinlerinin binayı terk etmelerine gerek kalmadan uygulanabilecek bir güçlendirme yöntemi araştırılmıştır.  Bu amaçla, özellikle (ülkemizdeki) mevcut betonarme binalarda sıklıkla görülen hatalara sahip olarak üretilen 1/3 ölçekli, deprem dayanımı zayıf, iki katlı ve tek açıklıklı güçlendirilmemiş tuğla dolgu duvarlı bir adet betonarme çerçeve referans numune olarak üretilmiştir. Ayrıca referans numune ile aynı özelliklere sahip 1 adet betonarme çerçeve dolgu duvarları, önüretimli yüksek dayanımlı yeni çapraz beton paneller ile güçlendirilerek deprem etkisini benzeştiren tersinir – tekrarlanır yatay yükleme altındaki davranışları test edilmiştir. Deney sonuçları, SAP2000 v17.3’de yapılan analitik çalışma ile karşılaştırılmış olup uygulanan tekniğin deney elemanlarının enerji yutma kapasitelerini artırdığını ve deprem davranışlarını iyileştirdiğini göstermiştir.
