Abstract
Winkler tipi elastik zemine oturan kirişlerin dinamik analizi İncelenmiştir. Elastik zemine oturan kirişleri idare eden denklemlere Timoshenko çubuk teorisi adapte edilmiştir. Laplace uzayında elde edilen skaler formdaki adi diferansiyel denklemler, problemin dinamik rijitlik matrisini kesin olarak hesaplamak için tamamlayıcı fonksiyonlar yöntemi yardımıyla sayısal olarak çözülmektedir. Elde edilen çözümler, Durbin'in sayısal ters Laplace dönüşüm yöntemi kullanılarak zaman uzayına dönüştürülmektedir. Elastik zemine oturan kirişlerin serbest ve zorlanmış titreşim analizi yapılmıştır.
The dynamic analysis of beams on elastic foundation of Winkler type is investigated. The governing equations for beams elastic foundation are obtaİned using Timoshenko beam theory. Ordinary differential equatİons İn scalar form obtained in the Laplace domain are solved numerically using the complementary functions method to calculate the dynamic stiffness matrix of the problem accurately. The solutions obtained are transformed to the real space using the Durbin's numerical inverse Laplace transfonn method. The free and forced vibrations of composite straight rods with variable cross-section are analyzed.
