Desenvolvimento de uma aplicação computacional para o dimensionamento de uma tesoura de madeira de cobertura, utilizando o Matlab

Abstract

This work aims mainly at the elaboration of a computational application that will perform the scaling of wood scissors used in coverage. The Matlab program allows the creation of software with a simple and practical graphical interface. In this work, a bibliographical review was also presented, which was used to automate the theories necessary for a scissors design in a proposed computational process. For the structural analysis, the finite element method was used, where the focus was the bar element. For the sizing of the bars, the criterion of the last limit state was adopted, where the bars are subjected to tensile and compressive stresses, and their sizing follows ABNT NBR 7190/97. This paper presents the main theories used in sizing, examples of each step, for further understanding, and a roadmap for using the developed software, with a practical step-by-step example
