COMPUTATIONAL IMPLEMENTATION OF A THREE-DIMENSIONAL FRAME ELEMENT SUBJECTED TO UNIFORM TEMPERATURE VARIATION

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 the tool does not have a certain function, the analyses may be restricted to more limited theoretical models that do not consider phenomena of temperature action on structures. Thus, this work proposes the development of a free and educational computational code capable of calculating displacements and requesting forces in three-dimensional frames subjected to uniform temperature variation. This code has been implemented in the Python language on the Visual Codes platform. The code has four processes for its creation, the first being the bibliographic review, the second the construction of the code, the third performing the test to verify the functionality and finally comparing the results with examples from the literature. The code that fulfilled the objectives established in this work was developed, a free educational tool for the calculation of three-dimensional frames with uniform temperature influence, having four validations for it, the first being simpler, a member embedded in the X axis with displacement only in this axis, the second a group of materials with displacement only in the X axis,  the third a two-dimensional frame, being X and Y with uniform temperature in one bar and the last more complex, a three-dimensional frame composed of 4 pillars and 4 beams with the addition of uniform temperature at the top of the structure. The results were compatible with those obtained in the literature.
