Comparação entre valores de ensaios experimentais e calculados da resistência ao embutimento da madeira de Pinus taeda L.

To design connections between timber parts with metal dowels (nails or bolts), two phenomena must be considered: bending of the metal dowel and the embedment strength in the wood. The Brazilian Standard ABNT NBR 7190:1997 proposes the methods used in the laboratory tests to determine the embedment strength with the metal dowell and, in the absence of testing, specifies relations to calculate the embedment strength from the compression strength. The aim of this research was to compare the embedment strength values obtained by experimental tests and calculated by the relationships established by the Brazilian Standard ABNT NBR 7190:1997. By the results of the hypothesis tests, it was possible to conclude that the estimate of the embedment strength parallel to the grain proposed by the Brazilian standard ABNT NBR 7190:1997, establishing equivalence with the strength compression results in the same direction, must be effective to the wood species Pinus taeda L., however, the same was not found in the perpendicular direction with respect to the grain, possibly explained by the alpha(e) values in the equation to calculed fe(90)

Avaliação econômica de diferentes composições veiculares empregadas no transporte rodoviário de madeira: estudo de caso

Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

Análise do comportamento térmico de paredes de madeira

This study consists in the observation and evaluation of the thermal behavior and distribution of wood composite walls, MDF – Medium Density Fiberboard, HDF – High Density Fiberboard, OSB – Oriented Strand Board and EGP – Edge Glued Panel. This study had the objective to present the experimental thermal behavior and to verify which one fit the thermal comfort standards for human labor For this work, was developed a thermal chamber, with one interchangeable side, so the wall prototypes would fit for each experiment. We studied walls made of MDF, HDF, OSB and EGP, which one had its own distinct behavior due to the panel construction. The EGP wall had shown the most reliable material for this usage at high temperatures. With this work, it was demonstrated the importance of choice for the right material and construction method for wooden composite walls, because if they were scaled poorly, the people exposed to them would be uncomfortable by the proportionate environment, and the costs for a resizing would be too high
