Estudio paramétrico del espesor de cimentaciones rígidas, utilizando la norma ACI 336.2R-88 y el modelo winkler por medio del programa SAFE

Abstract

This research addresses the static interactions between the foundation slab and the soil, considering various variables that affect its structural response. Parameters such as the number of levels, distances between columns, slab thickness, and underlying soil stiffness are analyzed to understand foundation behavior. The research takes into account the ACI 336.2R-88 code as the regulatory framework, providing guidelines to define whether the foundation slab is rigid or flexible. The software ETABS was used to generate structural models and obtain solicitations, along with the SAFE program for foundation design. The methodology focuses on the application of elastic foundation theory and Winkler theory, employing advanced analysis tools such as the finite element method, which involves dividing a structure into discrete elements within software. The software numerically solves mathematical equations, providing detailed information on stresses and deformations in the analyzed structure to evaluate the geotechnical-structural response under various conditions. The application establishes a solid theoretical framework for understanding the soil-structure interaction in the specific context of foundation slabs. Various results have been obtained covering different fundamental aspects for the analysis and design of foundations. Through static linear analysis, solicitations applied to each column have been determined for use in SAFE. Regarding the design of foundation slabs, necessary heights have been established considering critical factors related to load and force distribution in the supporting soil. The characterization of the deformation profiles of the foundation slabs in contact with the soil has been carried out by tabulating data obtained through the specialized software SAFE.
