Comentários Técnicos: Manual de Projeto e Construção de Estruturas com Peças Roliças de Madeira de Reflorestamento

This paper aims to provide a succinct chapters approach of the handbook "Manual de projeto e construcao de estruturas com pecas rolicas de madeira de reflorestamento", published in 2010, on the EESC/USP. The handbook presents recommendations for design and construction with pieces of roundwood from reforestation. Besides of a database of properties of strength and stiffness of roundwood of eucalyptus and pines, also shows the used class systems and methods of wood treatment to ensure durability, the usual types of connections between the structural elements, the types of structural systems and constructive examples of column sizing, roundwood purlin and tables pre-sizing bridges roundwood beam, bridges in mixed plate of timber-concrete with roundwood, and timber frame structure. At the end of the handbook were attached 124 fact sheets and project works constructed in Brazil and abroad using roundwood as examples of architectural and engineering, with emphasis on the potential use of this noble material as an alternative for sustainable construction.
