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.
