RESUMO:

In this work was analyzed the influence of soil under pile-cap on the response of an
reinforced concrete frame structure designed to support vibrating equipment, thus
under the action of dynamic excitations of large magnitude. The foundation of this
structure is composed of bore-role piles connected to the superstructure by a rigid pilecap.
For the evaluation of their structural response were considered numerical models
based on finite element method (FEM), adopting Winkler's model for the rheological
behavior of soil.
Specifically, was assessed the influence of pile stiffness and contribution of soil under
pile-cap. Notably was evaluated the displacements and pile reactions.
From the results obtained, it can be seen that the contribution of soil under pile-cap
was too small for the case study examined.There were not variations in the deformation, but in relation to pile reactions, variations suggest that for foundations with large number of piles, some savings can be achieved by considering the contribution of the soil.
