Abstract
Bu çalışmada, çekme almayan Pasternak zeminine oturan bir sonlu kirişin harmonik tekil yük etkisi altında titreşimleri Timoshenko kiriş teorisi çerçevesinde incelenmiştir. Kirişin zemine tam batmadığı kabul edilerek probleme ait yönetici denklemler elde edilmiş ve analitik/sayısal yöntemlerle çözülmüştür. Zemin ve boyutsuz zorlama frekansı parametreleri ile dönme eylemsizliği ve kayma deformasyonunun ayrılma noktasının yeri ile düşey yer değiştirmeler üzerindeki etkisi grafikler yardımıyla incelenmiştir.
In this study, within the framework of Timoshenko beam theory, forced vibrations of a finite beam resting on a tensionless Pasternak foundation under the effect of a harmonic concentrated load is investigated. Assuming that the beam is partially in contact with the foundation, the governing equations of the problem are obtained and then solved by using analytic/numerical methods. The effects of foundation parameters, dimensionless forcing frequency parameter, rotatory inertia and shear deformation on the coordinate of the lift-off point and the vertical displacements are studied by means of graphics.
