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 SL - Channel with Long Slots . . . . . . . . . . . . . . 0.90 H - Channel with Holes . . . . . . . . . . . . . . . . . . . 0.95 KO - Knock-Out Channel. . . . . . . . . . . . . . . . . . 0.95
