Determination of the crushing resistance in Paraná Pine wood

Abstract

Considering that in Argentina there are a few species of wood characterized for structural use, it is important to verify the values established in The Regulation CIRSOC 601, for those of common use. In this work, the resistance to crushing of Paraná Pine wood from implanted forests in the province of Misiones is determined. For this purpose, 131 specimens of 24 mm thickness were tested with a rigid bolt of 10 mm diameter, in accordance with UNE-EN 383:2007, of which 62 were tested with the load applied parallel to the fiber and 69 in perpendicular direction. The values of characteristic embedment strength percentile 5%, obtained were 34,43 N/mm² for the parallel direction and 23,36 N/mm² for the perpendicular direction. These values are significantly lower than those indicated in Table S.4.1.1-1 of Supplement 4 of CIRSOC 601.
