| Research Abstract |
Effects of dynamic interaction to the soil-structure system have been discussed by many researchers and aseismic design procedures taking into account the interaction effects are strongly expected. So an objective of this study is to establish a performance based aseismic design procedure taking into ac count dynamic Soil-structure interaction system. Our results are summarized as :
(1) we try to incorporate the effects of the dynamic soil-structure interaction can be adapted briefly in the simple Sway-Rocking(SR) model. The procedure to evaluate the sway and rocking springs, however, has not been well established yet. We here propose the method to evaluate the soil springs of the soil-pile interaction by using pushover analysis. The results are compared with those of the finite element analysis and both are in good agreement.
(2) Strength demand spectra taking into account soil-pile-interaction system are proposed and the characteristics of those specta are discussed.
(3) we examined the effects of the inelastic behavior of the pile-foundations on the aseismic performance by comparing the strength demand spectra. We investigated the relationship between the inelastic deformation of the pier and the pile-foundation on the aseismic performance of the structure systems.
