This paper introduces a rational method to analyze the inverted T-section strip footing resting on expansive soil. A computer program called SFOEES using the suggested analysis procedure was created to obtain the solution. The program SFOEES involves two major problems that are solved independently for simplicity. Firstly, estimating the distorted soil surface by solving Mitchell’s suction diffusion equation using the FDM in 2D and using Wray’s model to predict the soil movements. Secondly, analysis of the strip footing-distorted soil surface interaction using the FEM and the Vlasov model. The program’s accuracy has been checked through comparison of its results with others’ results and shown to be valid. The program was also used to investigate the behavior of the inverted T-section strip footings of different stiffnesses resting on expansive soil and subjected to columns’ loads of a lightweight structure consisting of a 3-story. It is concluded that the case of edge heave is considered the critical case for the distortion criteria and the maximum positive bending moment whereas, with regard to the negative bending moment, the case of edge shrinkage is considered the critical case.
