The effect of embedment on a foundation subjected to vertical vibration – a field study. J. S. Afr. Inst. Civ.

The response is typically quantified in terms of a number of parameters that include the displacement, the dynamic stiffness, the resonant frequency, the amplitude at the resonant frequency and the natural frequency. The objective of this study was to investigate the vertical dynamic response of an embedded foundation experimentally. It was found that embedment increases the stiffness, damping and natural frequency of a foundation system, reduces the displacement and resonant amplitude, but that embedment has very little effect on the resonant frequency.enAll the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.EmbedmentMachine foundationsVertical vibrationResonant frequencyVertical dynamic responseEngineering, built environment and information technology articles SDG-09SDG-09: Industry, innovation and infrastructureEngineering, built environment and information technology articles SDG-11SDG-11: Sustainable cities and communitiesArticle
