Influence of Static Vertical Subgrade Reaction on Soil-Structure Interaction

For the most reliable and realistic determination of structural behavior, the most recent theories of structural analysis define buildings as systems consisting of three components: superstructure, substructure, and foundation soil.

The conventional calculation of soil settlement, (Chapter 2.1.7 Estimated Vertical Settlement) is generally only a good estimate of the level of deformation that can occur when a load is applied, however, for a refinement of the calculation several factors must be considered, such as they are the definition of rheological models that express the behavior over time and the Soil Structure Interaction (SSI), the main study objective of this degree project.

The Soil Structure Interaction (SSI) will be treated, assuming a spatially homogeneous soil, and also considering the effect of uncertainty or heterogeneity; Hence, knowing the sensitivity of the structure from homogeneous and non-homogeneous parameters of the Vertical Reaction Coefficient of the support soil will be the objective of this project in question.

Using methodologies that take into account the effects caused through the Soil-Structure Interaction (SSI) is a more realistic evaluation of the structural behavior of buildings. Therefore, the conclusions of this degree project, based on a more precise estimate of this behavior, may be advantageous, not only economically, but also to provide a higher level of safety and reliability in buildings.

Nowadays, computational methods are indispensable tools in the execution of this task and allow the realization of increasingly realistic and reliable numerical analyses, so in the case of the degree project, the structural analysis software (RFEM 5 and RF -SOILIN www.dlubal.com) based on the finite element method is used as a tool, in order to study the effects of soil-structure interaction in the building type, under different soil support conditions.
