Loads may not be increased for short-term loading.
Uplift loads are based on DF/SP lumber, and have been increased 33% and 60% for wind or earthquake loading with no further increase allowed. Divide (133) Load by 1.33 for normal loading such as in cantilever construction. For SPF use 0.86 x DF/SP uplift load.
When I-joist is used as header, all nails must be 10dx1 1/2 and allowable loads assume flanges that are at least 1 1/2" thick made of Douglas Fir, LVL or TimberStrand® LSL. For other flange thicknesses, apply load adjustment factors found in the table on the right.
Hangers sorted in order of recommended selection for best overall performance and installation value.
Web stiffeners are required when supporting double I-joists with flanges less than 1 5/18" thick
NAILS: 16d and 16d DPLX = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long, 10dx1 1/2= 0.148" dia. x 1 1/2" long. See other nail sizes and information.
