3. Strength and Stiffness of Cross Laminated Timber (CLT) panels produced with Pinus and Eucalyptus: experimental and analytical comparisons
ABSTRACT The CLT is a building material that comes mainly used in Europe where it was developed. Lightweight, sturdy and eco-friendly, this material has become one of the most important constructive methods in the world. CLT are panels formed by layers of wood glued to each other orthogonally, always in odd numbers, symmetrical with respect to the central la

5. CHEMICALLY TREATED GLUED LAMINATED PARICÁ TIMBER (Schizolobium parahyba var. amazonicum)
ABSTRACT In the production of glue-laminated timber (GLT), boards derived from planted forest wood with easy workability are glued on top of one another. The main objective of the present work was to evaluate the performance of paricá timber GLT beams (5 × 10 cm) on GLT. Three procedures were performed: (1) GLT beams (5 × 10 cm) were produced using natura

6. Mechanical tests on Corymbia citriodora battenboard panels coated and reinforced with giant bamboo veneers
RESUMO Painéis sarrafeados de madeira densa geralmente rompem na linha de cola, ao serem carregados. Objetivou-se mostrar que lâminas finas obtidas de colmos maduros de Dendrocalamus asper, por meio de torneamento mecânico, são apropriadas para revestir e reforçar tanto a madeira de eucalipto processada, com pequenas espessuras, como painéis sarrafeado

7. Evaluation of Tensile Strength of a Eucalyptus grandis and Eucalyptus urophyla Hybrid in Wood Beams Bonded Together by Means of Finger Joints and Polyurethane-Based Glue
Created in the 1940s, the splice finger-joint type for wood has now been more used to compose structural materials wood base as Glued Laminated Timber (Glulam) and Cross Laminated Timber (CLT). The main advantage of this amendment is to provide a simple and economical way to join timber parts on segments. This study evaluated by means of tensile tests the ca

8. Influência de um corte na borda tracionada de uma viga maciça simulando uma emenda de topo na lâmina inferior de vigas laminadas coladas / The influence of a cut in the tensioned edge of a solid beam simulating a butt joint at the bottom lamination of glued laminated beams
A madeira laminada colada (MLC) é um produto estrutural que permite racionalizar o uso da madeira sólida, pois a partir de pequenas peças selecionadas e preparadas é possível produzir grandes vigas das mais variadas formas. A utilização da madeira de reflorestamento na produção de MLC lhe confere vantagens ambientais sobre outros materiais e o Eucal

9. Utilização de madeira de eucalipto de pequenas dimensões na fabricação de uma ponte protendida com madeira laminada colada / Use of small-sized eucalyptus wood to build a pre-stressed bridge with glued-laminated timber
This study aimed to build and evaluate the behavior of a highway stress-laminated timber bridge deck measuring 6m in length, 3.5 m width and 0.24 m thickness submitted to a load of 13 t. The deck was built with laminations made from eucalyptus logs of various thinning-originated specimens, with a mean diameter of 2.5 m and ages ranging between 8 and 19. To b

10. Use of castor oil-based polyurethane adhesive in the production of glued laminated timber beams
Researchers from the Polymer Technology and Analytical Chemistry (LQATP) group at the São Carlos Institute of Chemistry, University of São Paulo, developed a polyurethane adhesive based on castor oil. In addition to deriving it from a renewable source, this adhesive is nonaggressive to humans and the environment. The purpose of this study is to investigate

12. Emprego de espécies tropicais alternativas na produção de elementos estruturais de madeira laminada colada / Employment of alternative tropical timber species in glued laminated timber structural elements production
Apesar da versatilidade da madeira, seu emprego fica, às vezes, dificultado por não serem totalmente conhecidas as suas propriedades e seu desempenho em diferentes condições de serviço. Neste trabalho, procura-se contribuir para um melhor aproveitamento das espécies tropicais alternativas, em especial no emprego para produção de elementos estruturais
