Steady-state response of an elastically supported infinite beam to a moving load
چکیده انگلیسی

The steady-state response of a uniform beam placed on an elastic foundation and subjected to a concentrated load moving with a constant speed has been investigated. The foundation is modeled by using one and two parameters. The mathematical form of the solution is justified by Fourier transform. It is observed that the steady state is not attained at supercritical speed of the load in the ideal undamped case. Numerical results are presented for maximum settlement, uplift and bending moment in the beam. The effect of difference in the modeling of the foundation is shown to be insignificant.
