Análise de resistência à compressão paralela às fibras da madeira de Eucapyptus grandis

Abstract

The demand for reforestation wood has been increasing over the years, creating the need for more precise information about its mechanical properties, which can be obtained by testing the compression parallel to the fibers. Due to the gap existing in studies on this kind of test, this study aims to show the results that can be obtained using the method, emphasizing its main characteristics and seeking a better understanding of the outcomes. To achieve the results, there were prepared test bodies from kiln-dried Eucalyptus Grandis boards, taken out of random from two batches of wood commercialized by a Brazilian forest industry company. After preparing the material, tests were conducted to characterize the wood, finding the results for its mechanical strength and enabling strength classification. The study highlights the differences between the strength class table of the 1997 version of the NBR 7190 standard and its updated version of 2022. The results indicate that Eucalyptus Grandis wood is suitable and safe for use in structures such as beams andcolumns for commercial and industrial buildings.
