dc.description.abstractA significant contribution to the seismic design procedure including soil-structure interaction (SSI) is a complete understanding of the scenarios causing detrimental SSI effects. In that regard, this paper analyses several realistic SSI scenarios in a systematic fashion to define the correlation between soil, structural, and system parameters and SSI effects on the structural response. In the analyses, a soil-shallow foundation-structure model that satisfies various requirements suggested by design building codes is utilized. The soil stratum is assumed to be equivalent linear and the superstructure is considered to behave nonlinearly. Parameters of the model are defined randomly via a rigorous Monte Carlo simulation while constraining the process to generate realistic models. These randomly generated models are then subjected to a suite of recorded earthquake ground motions with different characteristics. Specifically, 1.36 million nonlinear time-history simulations are run covering realistic variations and combinations of soil, structure and earthquake ground motions. From the results, key parameters whose variation significantly affects structural response due to SSI are identified. The critical range of variation of these parameters resulting in a detrimental SSI effects is also depicted in a comprehensive statistical presentation. The comprehensive representation of the critical parameters provides a well-defined basis for incorporation of SSI in a seismic design procedure.en
