DYNAMIC RESPONSE OF RECTANGULAR PLATE SUBJECTED TO MOVING LOADS USING SPECTRAL FINITE STRIP METHOD

This paper presents development of spectral finite strip method for dynamic analysis of thin rectangular plates subjected to moving loads. Dynamic stiffness matrix of a plate strip in frequency domain is derived. For obtaining dynamic response of plate subjected to moving loads, both Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) are utilized. Numerical examples are presented to validate accuracy of the presented method.
