Desenvolvimento de ferramenta computacional para análise de estruturas reticuladas planas

Abstract

Work on the development of a computational tool for the analysis of plane reticulated structures. The structural analysis is the stage responsible for idealizing the behavior of a structure, having a great importance for the design of an engineering project. In general, the structural analysis has the primary purpose of determining internal and external forces, displacements, tensions and deformations, taking into account the possible stages of loads and requests to which the structure is submitted. If performed manually, the calculations involved in this step can become extremely complex and slow, and it may be necessary to use computational tools to obtain these results. However, such tools are not always available at affordable costs or have the desired calculation routine. These factors are crucial for the engineer to motivate himself to develop his own tools, which, although simpler, contemplate the particularities desired. In this sense, this work presents the concepts of the finite element method for the analysis of plane reticulated structures (trusses, beams and frames), through the development of a computational tool, coded in the Python programming language, with the aid of code libraries for scientific applications (NumPy, ScyPi and MatPlotLib). In its first version, the developed application is able to process the individual elements of a structure, perform the structural analysis, display the internal stress diagrams and show the support reactions
