The ultimate tensile strength requirements of Griplam nails (glulam rivets) were changed by the 1976 edition of CSA Standard 086. This action reduced the working loads for the nail-yielding mode of connection failure by 8%. To verify that the adopted factor of safety against yielding was retained, 12 large connections varying in predicted tensile capacity from 42–126 kips (187–560 kN) were tested. A bending specimen was chosen that served very well in three of the four load levels. The tests confirmed the predicted ultimate capacity of 1400 lbf (6230 N) per nail for a 3 in. (76 mm) or more penetration of dry Douglas-fir wood with loading parallel to grain. Other related aspects are discussed.
