A Series of 10 full scale tests were conducted on roof sub-assemblages cons
isting of open web steel joists and roof deck. In these specimens the roof
deck was fastened to the joists by using either 5/8-in. diameter puddle wel
ds or by using power-actuated fasteners (PAFs). PAFs are small high strengt
h nails pneumatically or powder driven through the roof deck into the joist
top chord angles. In these tests, the joists and roof deck were loaded to
failure under downward acting vertical loads. The purpose of these tests wa
s to determine if the presence of the PAFs produced any detrimental effects
on the gravity load capacity of a joist roof system. The test results show
ed essentially identical performance for specimens using puddle welds as fo
r specimens using PAFs. The PAFs produced no detrimental effects on the loa
d capacity of the joists in these tests.
