Research Abstract

A hybrid study has been made of nonlinear seismic soil-structure interaction by numerical analysis of the governing differential by on-line computer. During this analysis the nonlinearity of stiffness of the system was measured experimentally by Pseudo-dynamic Test, and fed back to the computer at each successive step. The other dynamic characteristics of the system were treated analytically.
We have used seven large foundation-structure models, which are shallow foundation, embedded foundation, caison foundation, 1-pile, 2-pile, 3-pile and 9- pile models. Also different seismic input excitations were used with a variety of different maximum amplitude.
Static and dynamic mechanical characteristics of soil-structure model were determined by Static and forced vibration Dynamic Tests. Frequency dependent dynamic characteristics measured through these tests were taken into account formulating dynamic equations of motion. We developed a new time domain numerical integration scheme that is based on the Hilbert Transformation of frequency dependent dynamic characteristics of the soil-structure system. Finally, we identified hysteretic restoring force and parameters using Kalman filter technique.
