Análise estrutural de um edifício em light steel framing considerando painéis de cisalhamento via modelo de duplas diagonais equivalentes

Abstract

Currently, systems such as Light Steel Framing have been gaining ground and consolidating in the market, as they enable construction with minimal waste, quick execution and better process efficiency. Thus, it is essential to study the different structural components that make up such a system. The sheating used in this system add to the panels a greater capacity to resist horizontal efforts, due to their considerable rigidity. However, most technical codes still do not address practical guidelines for their consideration in structural designs. Thus, the present work proposes to approach the theme by performing an analysis of a structure in Light Steel Framing, composed of seven floors, with the objective of evaluating its lateral displacement considering the Oriented Strand Board panels in the modeling of the structure via the equivalent double diagonal model and compare it with the traditional approach, using simple diagonals. At the end of this study, it is conclu ded that the double diagonal model used is capable of adequately representing the rigidity of the structure's panels, presenting itself as an interesting alternative for practical analysis and design purposes.
