Resumo

The objective of this article is to confirm the different behavior of the traditional slab foundation against a lightened, making a comparative analysis, using the MEF, of the first solution with a lightened slab using expanded polystyrene (EPS) blocks, joining solid areas on pillars with grating beams. Therefore there are two top and bottom plates covering the EPS blocks. The results obtained allow assert ourselves that in situations of soft soils, with possible problems of settlements, the proposed solution has significant advantages by reducing them a percentage will vary depending on specific conditions. Besides this, it reduces significantly the differential settlements between supports, so this alternative has a more uniform behavior, as well as constructive advantages.
