Dimensionamento e detalhamento de ligações metálicas

Abstract

The use of metal structures presents certain particularities; the material is already produced with predefined dimensions, making it necessary to establish connections, either through welding or by means of screws, in order to ensure the continuity of the pieces, as specified in the structural project. Since the year 2021, the new public procurement law, Law No. 14,133/2021, already stipulates in its text that Building Information Modeling (BIM) will preferably be adopted for the planning of new public works. Therefore, understanding and developing projects with this innovative technology has become the new norm in the sector. The objective of this work is the elaboration of details of metal connections through the use of drawing software that incorporates BIM technology. The main focus is on a comparison between welded and bolted connections and how their use alters the necessary pieces for the same building. The study details the main connections, analyzes the peculiarities of each method, and concludes that each approach presents specific advantages depending on the unique characteristics of the project in question.
