ABSTRACT
The vibration transmitted through the ground from various sources like machine operation, railways, highways, and industrial activities poses several threats to nearby structures. Understanding the attenuation response of such vibrations is crucial. The current study examines the attenuation response of machine foundations under horizontal excitation using a 3D finite element (FE) analysis. The dynamic response is recorded at different monitoring points from the source of vibration at distinct frequencies. Furthermore, the influence of different parameters such as soil density, shear wave velocity, damping ratio, frequency of excitation, and Poisson’s ratio is thoroughly investigated. The results indicate that the attenuation response of vertical and horizontal vibrations is found to vary significantly. In addition, the wave interference effect can be observed for horizontal vibration.
