ABSTRACT
It is hypothesized that interplay of earthquake, soil, foundation and structure (SFS) dynamic characteristic, and their interaction in time domain, control the behavior of SFS system during earthquakes. Moreover, (passive and active) control of spatial and temporal location of seismic energy dissipation (preferably in soil) can improve safety and economy of SFS systems. Such energy dissipation by design requires high fidelity modeling and simulations. This paper briefly describes modeling and simulation aspects of energy flow in SFS system. In addition to that, examples of directed energy dissipation are presented that show how soil can be used for the benefit of overall SFS system response to seismic excitation.
