IMPROVING THE BEHAVIOR OF RC FRAMES BY USING LIGHTWEIGHT CONCRETE PANELS AND METALLIC ELEMENTS

Abstract

In this study, the effect of two different wall systems which are composed of the structural lightweight concrete panel and metallic elements between the wall and frame on the behaviour of the RC frame is investigated numerically by using the Abaqus software. In the second type of wall system, a polyurethane-based binder was used between the wall and the RC beam. A quasi-static lateral loading was applied to 5 different full scale RC frames with and without walls, and frames were pushed 80mm laterally. In the worst case, the wall system carried 1.52 times the lateral load bare frame carried, whereas in the best case, the frame with the wall system carried 2.12 times the load bare frame carried. When thinner metallic elements were used, the elements yielded. This is promising for increasing damping in structures also. The second type of wall which interacts with the beam increased the initial lateral stiffness of the frame by 156% when compared with the bare frame. All frames conducted a ductile behavior and bare frame results are validated by comparing with previous study.

HAFİF BETON PANEL VE METALİK ELEMAN KULLANILARAK BETONARME ÇERÇEVE DAVRANIŞININ İYİLEŞTİRİLMESİ

Öz

Bu çalışmada, yapısal hafif beton panel ve duvar ile çerçeve arasındaki metalik elemanlardan oluşan iki farklı duvar sisteminin betonarme çerçeve davranışına etkisi Abaqus yazılımı kullanılarak sayısal olarak incelenmiştir. İkinci tip duvar sisteminde duvar ile betonarme kiriş arasında poliüretan esaslı bağlayıcı kullanılmıştır. Duvarlı ve duvarsız 5 farklı tam ölçekli betonarme çerçeveye yarı statik yanal yükleme uygulanmıştır ve çerçeveler yanal olarak 80 mm itilmiştir. En kötü durumda duvarlı sistem, çıplak çerçevenin taşıdığı yanal yükün 1.52 katını taşırken, en iyi durumda duvarlı çerçeve, çıplak çerçevenin 2.12 katını taşımıştır. Daha ince metalik elemanlar kullanıldığında elemanlar akmıştır. Bu aynı zamanda yapılarda sönümün arttırılması açısından da ümit vericidir. Kirişle etkileşime giren ikinci tip duvar, çerçevenin başlangıç yanal rijitliğini çıplak çerçeveye göre %156 oranında arttırmıştır. Tüm çerçeveler sünek davranış sergilemiştir ve çıplak çerçeve sonuçları önceki çalışmayla karşılaştırılarak modelin güvenilirliği doğrulanmıştır.
