1 . Safety factor , Ω , for tabulated values is 4.0 . 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 475 lbs ( 2.11 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 104 .

1 . Resistance factor , ϕ , for tabulated values is 0.35 . 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 640 lbs ( 2.85 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 104 .
