THREE-DIMESIONAL SEISMIC ANALYSIS FOR SOIL-FOUNDATION-SUPERSTRUCTURE BASED ON DYNAMIC SUBSTRUCTURE METHOD
|
抄録（英）：
This paper present an efficient 3-dimentional seismic analysis for a soil-foundation-superstrcture system. The dynamic substructure method is used to advantage in formulating the whole system as an integral of the far-field, the near field, the foundation and the superstructure. An axisymmetric modeling is taken for the soil and foundation in order to account for its 3-demensional body with use of the Fourier harmonics expansion for response in the circumferential direction. The interface or the interbody partitioning is applied between foundation and surrounding soils, depending on the type of the foundation concerned. The general 3-dimentional analysis is carried out for the superstructure for its complex geometry. The coupled motion between the soil-foundation system and the superstructure is formulated from the component modes method to attain a drastic reduction of the degrees of freedom for frequency response analysis. Case studies are given as numerical examples.
