The study presents a numerical investigation of the response of footing under the influence of dynamic load placed on an elastic half-space. The geometrical features of the footing and its distance from the source of vibration are normalized in terms of Rayleigh wavelength. The objective is to study the effect of nearby footing on the propagation of surface waves for different footing dimensions. The study mainly focuses on the maximum displacement amplitude with and without footing, and the vibrational amplitude for varying dimensions of footing. The soil and the footing are assumed to be linear-elastic, isotropic, and homogeneous. The effect of dynamic response on a neighboring footing is obtained in terms of amplitude ratio (𝐴R), which is the ratio of peak displacement amplitude with footing to the peak displacement amplitude without footing. In this study, it is observed that the amplitude ratio decreases with an increase in the width of the footing. However, the decreasing trend is not the same in all the cases. The amplitude ratio marginally decreases with an increase in thickness and depth of footing. However, a reverse trend is observed for a higher thickness and depth. Therefore, no generalized conclusion can be made on the effect of footing thickness and depth on amplitude ratio. It is observed that for all the cases, the percentage reduction ranges between 57% and 28% for different dimensions of footing. Observations from the study imply that vibrational amplitude significantly reduces due to the footing.
