Soil Structure Interaction
This chapter addresses the interaction between the structure and its foundation. It begins with a seldom covered problem: rocking of the structure on the foundation and possible “lift-off” that would act as stress reliever. Different techniques to model this problem are outlined. Then, deconvolution, the technique to apply a proper seismic excitation at the base of a model foundation as opposed to the accelerations recorded at the surface, is presented. It will be followed by the derivation of the wave equation which is essential to understanding the most commonly used soil structure interaction (SSI) model: the one by Lysmer. Then, the roles of both SSI and adjoining free field are discussed in a model developed by the first author along with a battery of simple validation problems highlighting the benefits of simple or complex SSI are presented. Finally, the chapter concludes with techniques to properly mesh a structure where the SSI is addressed.
