Light steel frame como alternativa à alvenaria convencional: aplicação em projeto arquitetônico

Abstract

This study aims to analyze the feasibility and necessary adaptations for converting an architectural project originally developed for conventional masonry into the Light Steel Frame (LSF) construction system. The research is based on the practical application of tools such as SketchUp, using the SketchFramer plugin, and the CYPE 3D software, focused on structural design. The study also includes a regulatory analysis, considering the requirements established by different technical standards. Furthermore, technical aspects of the system’s components are discussed. The methodology involved adapting the design of a mixed-use building (commercial and residential), located in Francisco Beltrão (PR), distributed over two floors. The analysis considered both structural compatibility and the feasibility of execution using an industrialized system. As a result, it was possible to develop a technical solution consistent with the principles of Light Steel Frame, highlighting its applicability in the Brazilian civil construction context. The paper also addresses the challenges faced during the modeling and structural analysis process, proposing viable solutions to the identified issues. It concludes that LSF represents an efficient, cost-effective, and sustainable alternative to traditional masonry, especially for medium-sized projects.
