ROCKING COMPLIANCE FUNCTIONS FOR RIGID BASES ALLOWED TO UPLIFT

A study is reported in which a static gravitational force and a static or dynamic overturning moment are applied to a rigid base on an elastic half-space, and an interative procedure is used to analyze the rocking response of the base with partial uplift. In the two-step study, the relationship between soil surface displacements and the surface tractions that the rigid base exerts on the soil (interaction forces) is derived from a boundary element analysis in the frequency domain. In the second step, displacements and tractions are modified in the time domain so that the boundary conditions are satisfied at the interface between the base and the soil. It was found that, in general, uplift leads to a softer vibrating system that behaves nonlinearly, i.e., rocking compliance increases with increasing values of the rotational moment. These and other study findings are presented and discussed.
