Nonlinear Behavior Analysis of SFRC Foundation Considering Homogeneous and Inhomogeneous Soil Interactions

Current structural design and analysis commonly use numerical simulation. Interactive problems often use this method to express the behavior of different types of structures when working together subject to external loads. This study shows the relationship between compression forces and displacements of a slab foundation that are directly interactive with inhomogeneous soil when using the stress-strain curve of steel fiber reinforced concrete material proposed by Barros and Figueiras [1]. The obtained results are better than the previous study of Vaskova and Čajka [3] when both experimental test results are compared. Otherwise, only using one type of element for both the foundation and the soil does not affect this interaction problem. The material model is an essential part of the simulation, and the problem should consider nonlinear behavior analysis.
