DYNAMIC RESPONSE OF TWO-DIMENSIONAL FLEXIBLE FOUNDATIONS ALLOWED TO UPLIFT

In the present paper, an approach for the numerical analysis of dynamic contact problems between elastic solids is presented. As a particular case the nonlinear effects that take place in dynamic non-linear soil structure interaction resulting from loss of contact between a flexible foundation and the surrounding soil are studied. The analysis is carried out by a time domain formulation of the Boundary Element Method (BEM). The non-linear problem at hand is solved following a step by step technique that may include an iterative process within each time step in order to determine the actual contact conditions (bonding, sliding with friction or debonding) at each point of the contact boundaries. Several applications in this field are studied and the results discussed in the paper.(A)
