An approximate analysis for kinetic response of triangular cantilever overhang
A simple approximate analysis of free and forced vibrations of a cantilevered triangular overhang under the separate action of moving load and pulsating load is given. The study, which does not consider the effect of the damping forces in the system, takes the first order approximation of the series to represent the shape of the normal modes of vibration as per rayleigh ritz method. The difference between the frequency values obtained by this method and those determined more precisely by using bessel's functions is, however, small, being in the order of 1.5 Per cent. The analysis obtains an easily applicable solution that may be of use either directly or with necessary modification to several practical cases of engineering interest; eg, unsupported corners of a rigid pavement, cantilever overhangs in bridge girders or decks, etc, where a high degree of precision may not be necessary. With a view to verifying the analytical findings, some experiments were conducted. The correlation between calculated and experimental results is satisfactory. (A)
