Abstract
Bu çalışmada tek katlı-tek açıklıklı ve üç katlı-tek açıklıklı olmak üzere laboratuarda inşa edilmiş küçük ölçekli çelik çerçevelerin dinamik karakteristikleri nümerik ve operasyonel modal analiz yöntemleri ile belirlenmiştir. Çalışmada ilk olarak çerçeve sistemlerin Sap2000 programında sonlu eleman modelleri oluşturulmuş ve dinamik karakteristikler nümerik olarak elde edilmiştir. Daha sonra sözkonusu çerçeve sistemlerin dinamik karakteristikleri operasyonel modal analiz yöntemi ile belirlenmiştir. Her iki analizden elde edilen sonuçlar karşılaştırıldığında ivmeölçer ağırlıklarının dikkate alınmaması durumunda deneysel ve nümerik olarak elde edilen frekans değerleri arasında önemli farklar oluşmuştur. Fakat sonlu eleman modellemesinde ivme ağırlıkları dikkate alınarak analiz yapıldığında her iki yöntemden elde edilen doğal frekans sonuçların birbiri ile uyumlu olduğu görülmüştür

Abstract
In this study, the dynamic characteristics of small-scale steel frames of one storey-one bay and three storey-one bay, which were built in the laboratory, were determined by numerical and operational model analysis methods. As a first step, finite element models of the frame system were built by using Sap2000 program, and dynamic characteristics of this system were obtained numerically. Then, the dynamic characteristics of mentioned frame system, is determined by operational modal analysis method. Comparison the results of both analyzes, significant differences between the frequency values, could be obtained in experimentally and numerically form, if ignored weight of the accelerometer. However, carrying out the analysis of finite element modeling considering the weight of acceleration, the natural frequency of the results obtained from both methods were found to be compatible with each other
