Abstract

Non-linear seismic soil-structure interaction is studied through a hybridprocedure using pseudo-dynamic testing method which is modified to take intoaccount frequency dependence and developed for foundation-soil systems. Thenumerical scheme used in conventional pseudo-dynamic testing is improved byintroduction of time-dependent pseudo-forcing function which is derived fromfrequency-dependent dynamic characteristics of the system by means of Hilberttransform in the frequency domain. Four large scale pile foundations, 1-pile, 2-pile, 3-pile and 4-pile models, were used. The mechanical characteristics of thesystems were determined from static and forced vibration dynamic tests. Anamplitude scaling technique, by which we could excite the systems with differentmaximum acceleration amplitude ranging from 60 to 300 gal, was used for the threeaccelerograms obtained.
