Metodologia para o cálculo dos módulos de elasticidade longitudinal e transversal em vigas de madeira de dimensões estruturais

Abstract: RESUMO Este trabalhou objetiva apresentar uma metodologia analítica para o cálculo dos módulos de elasticidade longitudinal (E) e transversal (G) em vigas de madeira de dimensões estruturais, segundo o emprego das teorias de vigas de Euler Palavras-chave: madeira, teoria de vigas, módulo de elasticidade. ABSTRACT This paper proposed a test method to obtain the shear (G) and longitudinal (E) modulus of elasticity in timber beams with structural dimensions, based on the static threepoints bending tests and the E… Show more

“…Also from data contained in the cited article, it's possible to infer that relation E G -1 is close to 20, for Jatobá. Christoforo, Ribeiro Filho, Panzera, and Lahr (2013) presented an analytical methodology for determination longitudinal and shear moduli for structural dimension lumber (proper to wood coming from planted forests), using three-point static bending tests; adapted from Brazilian Code NBR 7190 (ABNT, 1997). Wood species used in these trials were Pinus elliottii and Corymbia citriodora.…”

“…The modulus of elasticity is directly related to the stiffness of the cement-wood composites, also reflecting in the composite deformation capacity and the cracking control capacity (Christóforo, 2013). In cement pastes, the modulus of elasticity depends mainly on the water:cement ratio and its porosity (Gutierrez and Cánovaz, 1995).…”

“…A utilização da madeira na construção civil, principalmente a empregada em estruturas perenes, está condicionada a alguns aspectos que favorecem o uso desse material como elemento estrutural, tais como: emprego de pré-tratamento contra a proliferação de organismos xilófagos, o dimensionamento correto seguindo prerrogativas de documentos normativos, o conhecimento das propriedades físicas e mecânicas da madeira, entre outros fatores (OLIVEIRA, 2001;BERTOLINI, 2011;CHRISTOFORO et al, 2012;CHRISTOFORO et al, 2013;ALMEIDA et al, 2013b;FERRO, 2013). Na construção de estruturas de madeira é necessário a realização de ligações entre os elementos estruturais.…”
