DYNAMIC SOIL-PILE-FOUNDATION-STRUCTURE INTERACTION: RECORDS AND PREDICTIONS

The problem of soil-pile-foundation-superstructure interaction is examined, and a simple rational procedure to analyse the response of a structure supported on pile groups is presented. This procedure combines theories for the computation of the dynamic impedances and kinematic-seismic response factors of pile foundations with a multi-degree-of-freedom structural model. The procedure is applied to compute the response of a bridge in Rio Dell, California, which was shaken by the Ms = 7.0 Petrolia earthquake in 1992. The predicted response agrees well with recorded data. The significance of considering the frequency-dependence of the pile foundation impedances in the analysis of the response of the superstructure is discussed. (A)
