This study developed an improved methodology for studying the behavior of moderately loaded mat foundations on expansive soils. A computer program BOSEF Beam on Swelling Elastic Foundation was prepared that includes modelling of the following phenomena 1 Two-dimensional steady-state moisture flow through foundations soils 2 Computation of subgrade distortion resulting from changes of soil moisture and total or applied stress and 3 Soil structure interaction of a loaded beam resting on distorted subgrade. The methodology does not require calculation of suitable edge moisture penetration distances, which is a major obstacle for the use of previously published simplified design methods. Comparisons of computed displacements were made with two test cases for which data were available. The results of this research show that program BOSEF yields meaningful insights into the behavior of mat foundations on expansive soils. Recommendations are proposed to modify the computer program to better simulate performance of mat foundations on expansive soils. Author
