Desenvolvimento de programa para cálculo e análise de seções estruturais com geometria livre

Abstract

Part of a civil engineer's job is to design structures in a way that not only guarantees safety, but promotes greater savings in the materials used in these constructions. This process is based on choosing the type of cross-section of each structural element, as well as the dimensions of the profiles of each component, and tends to be slower and more laborious when done manually. The present work aims to develop, using the JavaScript programming language, a computational tool that helps engineers and engineering students to calculate geometric properties and internal stresses acting in plane sections based on the coordinates of the vertices of polygons that represent these sections, making faster the pre-dimensioning step. The program's applications can also be extended to several other areas beyond the design of structures in civil engineering, such as studies related to geography, topography, hydrology, hydraulics, mechanics and countless other applications. The results of numerical examples showed that the software proved to be effective, accurate and especially useful when used for analysis and design of sections with unconventional geometries.
