Yığma duvarlara yeterli dayanım ve rijitlik kazandırılması içinmantolama, katman ekleme vb. gibi farklı yöntemler uygulanarak pek çok deneyselçalışma yapılmıştır. Ancak bu yöntemlerin etkin olmalarının yanında, uzun biryapım süresi gerektirmesi ve mimari görüntünün bozulmasından dolayı yeni biruygulamanın geliştirilmesi gerekmektedir. Bu çalışmada, çelik lifli betonpaneller kullanılarak yığma duvarların ucuz, kolay üretilebilir ve pratik birbiçimde güçlendirilmesi sağlanmıştır. Çalışma kapsamında, gazbeton (GB)kullanılarak üretilen toplam 4 adet duvardan 3’ü belli oranlarda çelik lifkullanılarak üretilmiş beton panellerle güçlendirilmiştir. Deneyler sonucunda;deney elemanları arasındaki dayanım, deformasyon ve enerji tüketme kapasitelerikarşılaştırılarak değerlendirilmiştir.

Various methods such as jacketing and adding oflayers, etc. have been studied for many years in order to improve lateralresistance and strength of the masonry walls. These methods are effective,however, they require a long application period and theimplementation of these methods may cause loss of architectural functionalityand deteriorate structural aesthetics. Therefore, the development of a newtechnique would be quite useful. In this study, masonry walls are strengthened withcontaining steel fibers, which are cheap, easy to produce and practical. This studypresents the  results of the tests onfour walls built with aerated concrete (GB), three of which were strengthenedsymmetrically using by concrete panels with specified amount of steel fibers. Theresults of the experiments are discussed with regard to strength, deformationand energy dissipation capacity.
