Performance-Based Design of Soil-Foundation Interface in Buildings Soil foundation interaction associated with heavily loaded shear walls during large seismic events may produce highly nonlinear behavior. Geotechnical components of the foundation are known to have a significant effect on the building response to seismic shaking. The nonlinearity of the soil may act as an energy dissipation mechanism, potentially reducing shaking demands exerted on the building. This nonlinearity, however, may result in permanent deformations that also cause damage to the building. The goals of this research are to develop and test procedures to account for the foundation nonlinearity in performance based earthquake engineering. The primary goal of the research at UC Davis is to produce archived test data at prototype stress levels, regarding the cyclic and permanent deformation behavior of shallow foundations over a typical range of moment to shear ratio, shear to axial load ratio, foundation embedment, and soil type. A second goal of the researchers at Davis is to develop a coupled macro-element "constitutive model" to simulate the cyclic rotation, sliding, and settlement of a shallow foundation subject to combined moment, shear and axial loading.
