Modelling the Static Interaction Between a Shallow Foundation and Soil Base Using Contact Conditions
Abstract The displacement of foundation due to the deformation of soil base has a significant effect on the internal forces and reactions resulted from an analysis of building structure. However, this effect is generally not properly considered, causing eventual large errors in structural analysis and design. In this work, the authors aim to model the interaction between a shallow foundation and soil base by using contact conditions to analyse the building structure which is simultaneously exerted by the external loading and deformation of soil base. The internal forces and reactions obtained with this analysis are compatible with the deformation of soil base—namely, the displacements of foundations are exactly the consolidated settlements of the soil base and the internal forces caused by the unequal settlement are also included in the results. Because of the nonlinearities of the contact conditions and the soil characteristics, the discrete equations resulted from the finite element discretization are nonlinear, which can be solved by Newton-Raphson scheme with the aid of tangent stiffness matrices.
