This study presents the results obtained from tests to determine the embedding strength in dowel-type joints, in the parallel direction and in the direction perpendicular to the fibers, of the Populus x canadensis 'Conti 12' forest species. The tests were performed according to the specifications established in the UNE-EN 383:2007 Standard using bolts of diameters 5, 6, 7, 8, 8, 10 and 12 mm. The embedding strengths were determined in both directions, with the results in the direction parallel to the fibers being higher than those obtained in the direction perpendicular to the fibers. In both cases the resistance values decrease as the pin diameter increases. The mean value of the crush resistance for all specimens tested in the direction parallel to the fibers was 25.8 N/mm2 and the 5% percentile value was 19.9 N/mm2. In the direction perpendicular to the fibers, the mean value was 17.4 N/mm2 and the 5% percentile value was 10.6 N/mm2. The mean value of the corrected density at a moisture content of 12% was 406 kg/m3. The resistance values were compared with those included in Supplement 4 of the Argentinean Regulation of Wood Structures CIRSOC 601 and were between 40% and 69% lower, depending on the direction of load application in relation to the fiber and dowel diameters.
