NUMERICAL ANALYSIS OF SLAB FOUNDATIONS. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

A finite element model was used in order to study the settlements and internal forces induced in slab foundations. The analysis considered slab foundations of different flexural stiffness under framed structures with finite and infinite basal dimensions. The stiffness of the superstructure was not taken into account. It was concluded that in slab foundations of framed structures of infinite extent, the simplified Winkler's solution is a very close approximation to the continuum-medium solution. However in slabs of finite extent, large differences can result in the values of settlements and internal forces computed by both procedures. When modelling the soil as an anisotropic linear elastic continuum medium, the maximum angular distortion and internal forces induced over the slab foundation are not significantly affected by variations of some of the supporting-soil properties, such as anisotropic ratio, Poisson's coefficients, and the shear modulus associated to a vertical plane. In any case the shear modulus is the parameter that can originate the most significant differences. (Author/TRRL)
