The use of structural steel profiles as an external shear bracing is one of the most preferable simple, time saving and cost-efficient strengthening method for an inadequate existing reinforced concrete (RC) structure against earthquake lateral loads in comparison to the other interrupting, irritating and destructive traditional in plane strengthening methods which need evacuation of houses. With the use of this method, inhabitants of building can continue their daily life as usual during the strengthening site work.
With this experimental study it is aimed to determine the shear performance of anchor bolts used to connect the steel lama to an RC single span frame depending on embedment depth. For this purpose, a special steel construction loading system has been designed and constructed and six RC column-beam frames are prepared and five of them were strengthened using steel lama connected to the frame with different numbers of anchors in different depths. And also an equation was found related with the shear performance of steel anchor bolts depending on the anchor embedment depth.

Mevcut betonarme bir yapının yatay deprem yüklerine karşı yetersiz kalması durumunda, evlerin boşaltılmasını gerektiren, kullanımını durduran, yıkıcı, rahatsız edici ve tahribatlı diğer geleneksel düzlem içi güçlendirme yöntemlerine göre yapısal çelik profillerin dıştan çelik kesme çaprazlarının kullanılması, en çok tercih edilen basit, zaman kazandıran ve düşük maliyetli güçlendirme yöntemlerinden biridir. Bu yöntem ile güçlendirme çalışmaları esnasında bina sakinleri günlük yaşamlarına devam edebilirler.
Bu deneysel çalışma ile çelik lamayı betonarme tek açıklıklı çerçeveye bağlamak için kullanılan ankraj bulonlarının gömme derinliğine bağlı olarak kesme performansının belirlenmesi amaçlanmıştır. Bu amaçla özel bir çelik konstrüksiyon yükleme sistemi tasarlanmış ve inşa edilmiş ve altı adet betonarme kolon-kiriş çerçevesi hazırlanmış ve beş tanesi çerçeveye farklı derinliklerde farklı sayıda ankrajlarla bağlanan çelik lama kullanılarak güçlendirilmiştir. Ayrıca ankraj gömme derinliğine bağlı olarak çelik ankraj bulonlarının kesme performansı ile ilgili bir denklem bulunmuştur.
