Abstract

In this article, the response of a vibrating footing (450mm diameter bearing plate) subjected to dynamic effects was studied. Accelerometers were used to record the accelerations of the simulated footing. Some high significant correlations between the vibrational parameters (for example, the dominant frequencies of loadcell, the displacements ... etc) and the ratios of dynamical pressures to statical pressures were found. The results also indicated that, as for the view points of low frequency vibration, the amplitudes of the simulated footing seemed to be the largest when vibrating at the smaller contact pressures. This was not well agreed with those cited in some previous literatures.
