Abstract

Bu
çalışmada, aynı anda hem kayma ve hem geniş mesnet etkisindeki çerçeveler
analitik, nümerik ve deneysel olarak incelenmiştir. Analitik çözüm için matris
deplasman yöntemi, sayısal çözüm için sonlu elemanlar yöntemi kullanılmıştır.
Hem kayma etkisi hem de geniş mesnet etkisini içeren rijitlik matrisi için açık
denklemler ortaya konmuştur. Bunun için bir model çerçeve deneysel olarak test
edildi ve maksimum çökme değeri elde edildi. Aynı çerçeve sonlu elemanlar
yöntemi ile modellenerek ve ayrıca önerilen yöntem ile de çözüldü. Üç yöntemin
sonuçları karşılaştırıldı. Önerilen yöntem başarıyla doğrulandı. Hem kayma hem
de geniş destek etkilerini içeren önerilen yöntem sonuçlarının, deneysel
sonuçlara ve sonlu elemanlar yöntemi sonuçlarına daha yakın olduğu görülmüştür.

Abstract

In
this study, frames including both the shear and the wide support effect was
examined analytically, numerically and experimentally. Stiffness method was
used for analytical solution and finite element method was used for numerical
solution. Explicit expressions for the stiffness matrix that includes both the
shear effect and the wide support effect are presented. A model frame was
tested experimentally, and a maximum deflection result was obtained. The same
frame was modeled and solved with the finite element method and with the
proposed method. The results of three methods were compared. The proposed
method was verified successfully. The proposed method, which includes both the
shear and wide support effects, produced results that were shown to be closer
to the experimental results and the results than were the results of the other
models that were investigated.
