Figure 102 - MT Channel-to-Steel
Table 253 - Allowable Strength Design ( ASD ) Load Data 1 , 2 , 3 , 4 , 5
F z lb ( kN )
1,350 ( 6.01 )
1 . Safety factor , Ω , for tabulated values is 3.0 . 2 . Tabulated values represent the total allowable load on a pair of beam clamps . The load resisted by a single beam clamp must not exceed 675 lbs ( 3.0 kN ). 3 . Multiply tabulated values by 1.5 to obtain minimum Load and Resistance Factor Design
( LRFD ) values . 4 . The design professional must account for moment decoupling when the applied loads do not occur between the pair of beam clamps . 5 . See Figure 102 .

F z lb ( kN )
1,820 ( 8.11 )
1 . Resistance factor , ϕ , for tabulated values is 0.45 . 2 . Tabulated values represent the total factored design load on a pair of beam clamps . The load resisted by a single beam clamp must not exceed 910 lbs ( 4.05 kN ). 3 . The design professional must account for moment decoupling when the applied loads do not occur between the pair of beam clamps . 4 . See Figure 102 .
