Gazbeton Malzemesinden Üretilmiş Duvarların Çelik Lifli Beton Panellerle Güçlendirilmesi: Deneysel Çalışma

Öz

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.
