Tek serbestlik dereceli çelik bir yapının sarsma tablası deneyleri

Bu çalısmada, tek serbestlik dereceli çelik bir yapının dinamik davranısı Çukurova Üniversitesi Mühendislik Mimarlık Fakültesi Đnsaat Mühendisliği Bölümü Yapı Laboratuarı’nda bulunan sarsma tablası kullanılarak deneysel olarak arastırılmıstır. Elde edilen deneysel deplasman verileri, CSI SAP2000 yazılımından elde edilen sayısal deplasman sonuçlarıyla karsılastırılmıstır. Deneysel ve sayısal çalısmada sinüzoidal ve gelisigüzel formlu ivme kayıtları kullanılmıstır. Yapılan analizler sonucu, sarsma tablasının yapıya istenilen yer hareketini basarıyla uyguladığı ve sonlu elemanlar yöntemini kullanan CSI SAP2000 yazılımının yapının dinamik davranısını güvenilir ölçüde belirleyebildiği görülmüstür.

Shake table tests of single degree of freedom-steel structure

In this thesis, dynamic response of a steel single degree of freedom structure was investigated using a shake table located in Structural Laboratory of Civil Engineering Department of Engineering and Architecture Faculty of Cukurova University. Experimentally acquired displacement data was compared with numerical displacement results obtained by CSI SAP2000 software. Sinusoidal and random formed acceleration data were used in the experimental and numerical work. As a result of performed analyses, it has been seen that, the shake table was applied desired ground motion successfully to the structure and CSI SAP2000 software which uses finite element method was able to determine the dynamic response of the structure reliably.
