1. ESTIMATION OF WOOD TOUGHNESS IN BRAZILIAN TROPICAL TREE SPECIES
ABSTRACT Wood has been used for several purposes such as in civil and rural construction. Knowing wood mechanical behavior under short-term loading is essential for safer structural designs. However, wood toughness is a mechanical property little investigated for this purpose. Thus, this study aimed to evaluate, using exponential and polynomial regression mo

2. Properties of Young Guapuruvu (Schizolobium parahyba) Wood from a Forest Recovery Area
ABSTRACT Guapuruvu is one of the fastest growing Atlantic Forest species. It is also considered one of most important species in forest recovery areas, starting to compete with other individuals during the second stage of succession, as well as showing a capacity to be harvested and processed at this stage, after fulfilling its function as a pioneer. There

3. PHYSICO-MECHANICAL CHARACTERIZATION OF THE Anadenanthera colubrine WOOD SPECIE
ABSTRACT In Brazil, the characterization of wood is carried out in accordance with the premises established by ABNT NBR 7190standard; however, the determination of wood properties requires the use of equipment, which hinders the wood characterization for the construction professional. To circumvent this problem, the properties of wood strength and stiffness

4. Strength and stiffness of thermally rectified eucalyptus wood under compression
The aim of this work was the evaluation of the thermal-rectification process of reforestation wood Corymbia citriodora Hook by measuring of mechanical properties under compression parallel to the grain and also determining of chemical composition. The tested samples were thermally treated in a furnace with nitrogen-atmosphere at heating rate of 0.033 ºC.min

5. Influence of wood moisture content on the modulus of elasticity in compression parallel to the grain
Brazilian Standard ABNT NBR7190:1997 for timber structures design, adopts a first degree equation to describe the influence of wood moisture content. Periodically, when necessary, the referred standard is revised in order to analyze inconsistencies and to adopt considerations according new realities verified. So, the present paper aims to examine the adequac

6. Estudo de elementos estruturais roliços de madeira / Study of structural round timber
The aim of this work is the determination of stiffness and strength properties of structural round timber. Static bending and compression parallel to grain tests were carried out to obtain modulus of elasticity (MOE), shear modulus (G) and modulus of rupture (MOR). The results suggest that, in bending test, there is no influence in MOE determination due to s

7. Influence of the specimen size on destructive methods of parallel compression grain and on the test non-destructive using ultra sonic waves / Influencia da dimensão do corpo-de-prova no ensaio destrutuvo de compressão paralela as fibras e no ensaio não-destrutivo utilizando ultra-som
é praticamente toda exportada em sua forma in natura sem que a ela seja agregado valor de beneficiamento. Um dos problemas enfrentados pela indústria moveleira é o fato da madeira não ser submetida à classificação, dificultando a elaboração de projetos e a certificação da qualidade do móvel confeccionado a partir deste material. Nesse contexto as
