Abstract
This paper presents the response of a solid elastic layer (slab) when subjected to
varying spatially sinusoidal harmonic line loads. The displacements within a
solid layer of infinite extent are obtained using 2.5D Greens functions derived
expressly for this case. These functions are included in a Boundary Element
Method (BEM) model to simulate a slab with lateral confinements. Only the
lateral boundaries need to be discretized with boundary elements. The problem is
formulated in the frequency domain. Time responses are obtained by applying
the inverse Fourier transform using complex frequencies. Different simulations
are performed to understand the effect of the lateral confinements on the final
response of the slab.
