A total of 188 specimens were tested in edge and plank bending to establish the characteristic value and volume adjustment exponent. Qualification test data were used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CAN/CSA-O86 was used to determine the specified strength.

A total of 28 full-size specimens were tested for on-edge shear and 53 block specimens were tested. Qualification test data were used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CAN/CSA-O86 was used to determine the specified strength.

A total of 53 specimens each were tested to establish the characteristic value. Qualification test data were used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CAN/CSA-O86 was used to determine the specified strength.

A total of 60 specimens were tested in edge and plank compression to establish the characteristic value. The characteristic value was multiplied by 1.09 to establish the specified strength in accordance with CAN/CSA-O86.

A total of 200 specimens were tested to establish the characteristic value and volume adjustment exponent. Qualification test data were used to establish the applicable coefficient of variation, CV_w, and the reliability normalization factor from CAN/CSA-O86 was used to determine the specified strength.

Nail withdrawal values were established following ASTM D1761-06 for an 8d common nail having a 38-mm penetration. Specimens were tested and equivalent species capacity was determined in accordance with ASTM D5456-10a, A2.

Nail bearing strength was determined in accordance with ASTM D5764-97a(2007) with 10d common nails with a nominal diameter of 3.76 mm. Specimens were tested and the mean bearing capacity was used to establish the equivalent species capacity as per ASTM D5456-10a, A2.

Bolt bearing capacity was determined in accordance with ASTM D5764-10a with 13-mm and 19-mm bolts. Specimens were tested and the mean bolt bearing capacity was used to establish the equivalent species capacity in accordance with ASTM D5456-10a, A2.
