Hafif Çelik Duvar Panellerinden Oluşan Bina Sistemlerinin Yatay Yük Altındaki Yapısal Davranışlarının İncelenmesi

Öz: Hafif çelik yapı sistemleri betonarme ve yapısal çelik sistemlere karsı hızlı üretim, hafiflik ve kolay yapım gibi avantajlara sahiptir. Ayrıca, teknolojik gelismeye çok fazla açık olmayan insaat sektöründe hafif çelik yapım yöntemi yeni bir yapım teknolojisi olarak kabul edilmektedir. Bu avantajları sayesinde, hafif çelik yapı sistemleri Dünya?da artmakta olan ragbete paralel olarak Türkiye?de de son yıllarda tercih edilen yapı sistemleri arasına girmistir. Dünya?da ve ülkemizde henüz yeni bir sistem olması ve betonarme ve agır çelik sistemlerden farklı olarak hafif çelik yapı sistemlerinin tasarımı ve imalatı konularında yönetmeliklerin yetersiz kalmasından dolayı, hızlı bir sekilde kullanılmaya baslanan bu yapı sisteminin düsey ve yatay yükler altındaki yapısal performansı ve güvenilirligi halen ciddi bir soru isaretidir. Hafif çelik duvar panellerinin yatay yük tasıyıcı sistem olarak kullanıldıgı binaların yatay yüklere karsı yapısal tasarımı ile ilgili mevcut olan bu ihtiyacın ve sistemin davranısı ile ilgili bilgi eksikliginin giderilmesine yönelik olarak, deneysel çalısmalardan olusmus olan bu proje gerçeklestirilmistir. Proje kapsamında tipik bir hafif çelik yapı sisteminde bulunan önemli elemanlar ve elemanlar arasındaki baglantılar üzerinde detaylı bir deneysel çalısma yürütülmüstür. Bu sayede, hem bu tür yapı alt bilesenlerinin davranısları belirlenmis hem de gerekli durumlarda yapısal performansın iyilestirilmesini saglayacak yeni yapım detayları incelenmistir. Ortaya çıkarılmıs olan bu bilgi birikiminin, bu tür yapı sistemlerinin global davranısının tam olarak anlasılmasında ve iyilestirilmesi yönünde uygulanabilecek esasların belirlenmesinde büyük fayda saglayacagı düsünülmektedir.

Abstract: Cold-formed steel (CFS) structural systems offer certain advantages over conventional steel and reinforced concrete systems mainly due to rapid fabrication, high strength/weight ratio, and relatively easy construction. CFS is also considered to be an innovative construction method, and is a practicle example of the use of new technology in construction industry. As a natural result of these advantages, CFS structural systems have recently been the preferred method of construction for an increasing number of structures both worldwide and domestically in Turkey. However, CFS is still a relatively new and untested system, and the few available design specifications lack sufficient detail for this system to be designed and constructed safely. As a result, there is a major concern regarding the performance of CFS structural systems under gravity and lateral loads. The current research program aims at improving the understanding of the structural behavior of a specific type of CFS building system, where the lateral load resisting system is made of shear walls sheathed with wood-based panels. An extensive and detailed experimental investigation on various components of a typical sheathed CFS shear wall system as well as the connections between these components was conducted as part of this study. This approach enabled not only the identification of the structural behavior of critical components and regions but also the investigation of new construction details that would improve the structural performance. The knowledge acquired as a result of these activities is expected to help a complete understanding of the global response of such systems and determination of guidelines towards improved response.
