Abstract

This work presents a computer-based analysis of semi-rigid steel frames. The geometric nonlinearity of the structure and the material nonlinearity of the connections are considered in the analysis. First, the stiffness coefficients of members have been obtained. Then, the stiffness matrices of members with nonlinear flexible connections have been developed based on the analytical solution of the second-order analysis equations. The King-Chen [11] model has been adopted for modeling the semirigid connections. An incremental and iterative Newton-Raphson solution procedure has been used for the analysis. The critical load has been searched as a suitable load parameter for the loss of stability of the system. Several examples are presented to demonstrate the validity of the analysis procedure.

Özet

Bu çalışmada yarı rijit bağlı çelik çerçevelerin bilgisayar destekli analizi sunulmuştur. Analizde çerçevenin geometrik nonlineerliği ve bağlantıların malzeme nonlineerliği gözönüne alınmıştır. İlk olarak, çubukların rijitlik katsayıları elde edilmiştir. Daha sonra, nonlineer esnek bağlantılı elemanların rijitlik matrisleri ikinci mertebe analizi kullanılarak elde edilmiştir. Yarı rijit bağlantıların modellenmesinde King-Chen modeli' kullanılmıştır. Analizde Newton-Raphson iteratif çözüm yöntemi kullanılmıştır. Kritik yük, sistemin stabilitesinin kaybolması için gerekli uygun yük parametresi olarak araştırılmıştır. Analiz yönteminin doğruluğunu sınamak için çeşitli örnekler çözülmüştür.
