Soil yielding beneath foundations can be an effective energy dissipation mechanism; however, this yielding may lead to excessive permanent deformations. The research and engineering community have established decades of model testing and analytical modeling to understand foundation nonlinearity and uplift. Physical model testing provides insight into the mechanisms at work in rocking, shallow foundations, while analytical modeling and simulation are validated against these experiment results such that modeling recommendations can be applied in practice. This body of work lead to the current design procedures in industry, such that the benefits and consequences of foundations allowed to rock under seismic events can be understood and implemented in practice generally for retrofit of existing structures. While there are various established analytical modeling approaches, this paper focuses specifically on both the elastic and nonlinear Winkler analytical modeling approaches used to better understand, mimic or approximate observations from experiment, current codified design procedures, and includes speculation on the future of research and design in this field.
