Análise da resistência mecânica de ligação com pino metálico em perfil de composto plástico reciclado

Abstract

This study aims to investigate the connections using metal pins in Wood-Plastic Composite (WPC), highlighting their importance in the design and dimensioning of structures. Considering the inefficient recycling practices in Brazil, often leading to the material being discarded as waste, the use of WPCs instead of conventional wood is significant, considering factors such as potential cost reduction and environmental impact. By following the guidelines established by NBR 7190/2022 and EUROCODE 5, which provide criteria and requirements for timber structure design, including specifications for connections, experimental tests were conducted. Through graphs and data analysis, the load-carrying capacity and performance of these connections were evaluated, aiming to contribute to the knowledge and safe application of this material. The obtained results demonstrated satisfactory strength of the connections using metal pins in WPC. However, further studies are needed to explore other types of connections.
