Relações entre propriedades de rigidez para distintas solicitações mecânicas visando projetos de estruturas de madeira

Abstract: Resumo No Brasil, o documento normativo NBR 7190 (ABNT, 1997) estabelece os métodos de ensaio para obtenção das propriedades físico-mecânicas da madeira. Na impossibilidade da determinação dos resultados experimentais, a norma estabelece relações entre propriedades. Porém as relações entre as propriedades de rigidez apresentadas foram determinadas com base no antigo referencial normativo MB-26:1940 (NBR 6230), que considerava outro modelo de cálculo e não ao utilizado pela norma brasileira. Nesse contexto, est… Show more

“…Thus, the use of non-traditional species for several applications worldwide requires specific knowledge of the physical and mechanical properties of wood, such as the fc0,k strength, which have great significance for wood products and construction (Wolenski et al, 2020). For hardwoods, usually applied for structural projects due to high mechanical strengths (Almeida et al, 2020b), the ABNT NBR 7190 (1997) As the C40 strength class contemplates a wide range of fc0,k, values, the C50 category (50 MPa ≤ fc0,k < 60 MPa), which is not included in the Brazilian standard document cited has been adopted by some literature studies such as Logsdon et al (2010), Lima et al (2018), Cruz et al (2021 and Wolenski (2022).…”

“…La madera se ha aplicado como material estructural desde los tiempos más remotos, motivado por sus propiedades mecánicas, abundancia y facilidad de manejo con herramientas simples (Almeida et al, 2020). Este material ha ido ganando protagonismo en la ingeniería estructural (Mam et al, 2020) y especialmente en el diseño de construcciones rurales (estructuras de techado), ya que la madera se caracteriza por ser un material de carbono cero (Bita;Tannert, 2018), además de ser una fuente renovable con un bajo consumo energético requerido durante su procesamiento (Bita;Tannert, 2018).…”
