Abstract (2. Language): 
The method of differential quadrature developed by Richard Bellman in the 1970s is a numerical solution technique for differential systems by means of a polynomial-collocation approach at a finite number of points. In this paper a global method of generalized differential quadrature is presented to solve the problems on deflection, buckling and vibration behaviour of structural components. Furthermore, the applicability of this method to the deflection analysis of beams due to a point load is also demonstrated. An inherent advantage of the approach is its basic simplicity and small computational effort with easy programmability. Results are obtained for various boundary and loading conditions and are compared with existing exact and numerical solutions by other methods. Numerical examples have shown the accuracy, efficiency and great potential of this method for structural analysis.
Abstract (Original Language): 
Richard Bellman tarafından 1970'lerde geliştirilen Diferansiyel Quadrature metodu, diferansiyel denklemlerin sonlu sayıdaki düğümlerinin, sayısal çözümüdür. Bu çalışmada Genelleştirilmiş Diferansiyel Quadrature metodunun, yapıların yer değiştirme ve burkulma analizine uygulanışı verildi. Ayrıca, kirişlerin tekil yük altındaki çökmesinin bu metoda uygulanabilirliği de gösterildi. Metodun en önemli bir avantajı, sistemlere basitçe uygulanabilirliği, hesaplama süresinin kısalığı ve programlamanın basitliğidir. Değişik sınır şartları ve farklı yüklemelerde elde edilen sonuçlar, mevcut gerçek ve sayısal sonuçlarla karşılaştırıldı. Elde edilen sonuçların çok ince hassasiyetle doğruluğu gösterildi.
