Beam loads shown are total uniform load, including the channel weight,
for a simple span supported at each end that is adequately laterally
braced.
Refer to pages 20 -23 for other beam support conditions.
Refer to page 77 for load reduction factor for an unbraced beam length.
Beam Loading of Punched Channels
Load for punched channel is obtained by multiplying the loads shown by the following reduction factors:
SS - Channel with Short Slots. . . . . . . . . . . . . . 0.90
