Yığma yapılarda duvarların deprem yükleri altında yetersiz yatay
dayanım ve rijitliğe sahip oldukları için hasar görme olasılıkları oldukça
yüksektir. Yığma duvarlara yeterli dayanım ve rijitlik kazandırılması için
mantolama, katman ekleme vb. gibi farklı yöntemler uygulanarak pek çok deneysel
çalışma yapılmıştır. Ancak bu yöntemlerin etkin olmalarının yanında, uzun bir
yapım süresi gerektirmesi ve mimari görüntünün bozulmasından dolayı yeni bir
uygulamanın geliştirilmesi gerekmektedir. Bu çalışmada, çelik lifli beton
paneller kullanılarak yığma duvarların ucuz, kolay üretilebilir ve pratik bir
biçimde güçlendirilmesi sağlanmıştır. Çalışma kapsamında, gazbeton (GB)
kullanılarak üretilen toplam 4 adet duvardan 3’ü belli oranlarda çelik lif
kullanılarak üretilmiş beton panellerle güçlendirilmiştir. Deneyler sonucunda;
deney elemanları arasındaki dayanım, deformasyon ve enerji tüketme kapasiteleri
karşılaştırılarak değerlendirilmiştir.

Strengthening Of Walls Produced From Aerated Concrete Material With Steel Fibered Concrete Panels: Experimental Study

Öz

Due to their insufficient
lateral strength and rigidity under earthquake loads, the walls are vulnerable
to damage in masonry buildings. Various methods such as jacketing and adding of
layers, etc. have been studied for many years in order to improve lateral
resistance and strength of the masonry walls. These methods are effective,
however, they require a long application period and the

implementation of these methods may cause loss of architectural functionality
and deteriorate structural aesthetics. Therefore, the development of a new
technique would be quite useful. In this study, masonry walls are strengthened with
containing steel fibers, which are cheap, easy to produce and practical. This study
presents the  results of the tests on
four walls built with aerated concrete (GB), three of which were strengthened
symmetrically using by concrete panels with specified amount of steel fibers. The
results of the experiments are discussed with regard to strength, deformation
and energy dissipation capacity.
