Desenvolvimento de uma rotina computacional para o cálculo da rigidez do sistema solo-fundação utilizando linguagem de programação Python

Abstract

In this monography, computational routines were developed to calculate the stiffness of the soil-foundation system in frame structures. For this, foundation mesh generators were produced in PYTHON programming language coupled to a frame structural processor, considering a simplified model of springs, in which the footings and piles are influenced by the soil through flexible supports. Building mesh generators with flexible supports were also included to consider the application of the soil-foundation system stiffness, allowing an analysis of the structural behavior of plan and three-dimensional buildings. From this, some examples of validation of the generated models, using rigid and flexible supports, were analyzed. For the examples with flexible support, the stiffness of the continuous soil-foundation set was applied from the individual foundation generators. From the results, it was verified that the generators were efficient for the analysis of the soil-structure interaction considering the stiffness of the soil-foundation system. A mesh generator version was also developed that performs the iteration of load steps considering, in this case, the possibility of soil stress variation due to the applied stress. The PYTHON programming language proved to be suitable for the intended computational implementations. Finally, the importance of studying the soil-structure interaction for an analysis of the structural behavior of buildings is evaluated.
