FOUNDATION RESPONSE TO HORIZONTAL VIBRATIONS

A solution is discussed for the prediction of the dynamic response of a footing subjected to horizontal vibration for a particular case only, the rigid base pressure distribution-weighted average displacement condition. As seen from literature the type of contact pressure distribution and displacement condition, namely central, average and weighted average, affect the dynamic response. In the present study, using elastic halfspace theory, the dynamic response of footings has been predicted for various cases where solutions are not available. Both frequency dependent and frequency independent excitations are considered. The results are presented in the form of tables and charts for ready use in design. As a simplified procedure, analog models have also been developed to predict the dynamic response for the cases where solutions are not available. The comparison of the results of analog model with elastic half-space theory is found to be good. (TRRL)
