IMPLEMENTAÇÃO COMPUTACIONAL DE ELEMENTO DE PÓRTICO TRIDIMENSIONAL SUBMETIDO À VARIAÇÃO DE TEMPERATURA UNIFORME

Abstract

The development of computational tools for structural analysis has solved structural problems. However, due to existing limitations for users who do not have the full license or simply because the tool lacks certain functions, the analyses may be restricted to more limited theoretical models that do not take into account the effects of temperature on structures. Thus, this work proposes the development of a free and educational computational code capable of calculating displacements and demanding forces in three-dimensional frames subjected to uniform temperature variation. This code was implemented in the Python language on the Visual Codes platform. The code has four processes for its creation, the first being the literature review, the second the construction of the code, the third conducting tests to verify functionality, and finally comparing the results with examples from the literature. The code has been developed to meet the objectives established in this work, a free educational tool for the calculation of three-dimensional frames with uniform temperature influence, having four validations for it. The first is simpler, a fixed beam along the X-axis with displacement only in that axis; the second involves a group of materials with displacement only in the X-axis; the third is a two-dimensional frame, along the X and Y axes, with uniform temperature in one beam; and the last, more complex, is a "table"-shaped frame with added temperature on the upper part of the structure in three dimensions. The results were consistent with those obtained in the literature, except for the last one, as it was created.
