Transfer Matrix法によるばねと減衰を有する移動荷重を受ける多径間連続ばりの動的応答解析

抄録

In the present paper, the analytical treatments of dynamic behavior of beams under moving loads with spring and damping are shown by using of transfer matrix method to determine the natural frequencies and mode shapes of the beams. We adopt the analytical theories such as Classical, Timoshenko's and Levinson's beam theories for the computations of dynamic behavior of multispan beam, in which the latter two theories take into consideration of the shear deformation and rotatory inertia of the beams. The accuracy, dynamic responses of multispan beams are illustrated through several numerical results by using of the three theories.
