Abstract
Coupled problems of the multi-degree-of-freedom-system (MDOF) or SoilStructure Interaction (SSI) are usually translated to a series of the single-degree-of-freedom (SDOF) equations. In this paper, the predominant periods of MDOF analysis are analyzed without SDOF and the dynamic amplification factors for a sample data of a model building are shown. The analysis method is the assumption that, as well as SDOF analysis, the MDOF analysis is applied to the predominant periods by inelastic analysis. That can give the dynamic amplification factors of the MDOF. At the results, it is cleared that the predominant period of the MDOF is close to be the period by the eigenvalues and in the short period or in the high level modes, the dynamic amplification factors are high which should not be neglected. Moreover, soil-structure interaction with SDOF are also analyzed by elastic analysis for the model building. Some effects to the building structure model by the rocking on the ground are discussed in the sway-rocking models.
