✦ Synopsis

The authors have presented [1] an interesting paper on the analysis of ground vibrations related to railway tra$c. Their work has extended previous presented analyses to take into account the e!ect of a layered supporting soil as well as the transient nature of ground vibrations related to railway tra$c. Results from calculations show the displacement pattern on the soil surface from a moving constant load as well as from a moving harmonic load. Di!erent relations between the load speed and the Rayleigh wave velocity of the supporting half-space or an upper layer on a half-space are investigated. The deformation pattern around a constant load travelling with sub-Rayleigh speed was found to be of

A sequence of results is presented from a model of an oscillating load moving on a track on a layered ground. The results allow a visualization of the e!ect of the relative speeds of the load and the propagation speeds in the ground structure. This is useful in developing the understanding of the in

Vibrational behavior of elastic homogeneous isotropic beams with general boundary conditions due to a moving harmonic force is analyzed. The analysis duly considers beams with four di!erent boundary conditions; these include pinned}pinned, "xed}"xed, pinned}"xed, and "xed}free. The response of beams
