1 . Safety factor , Ω , for tabulated values is 2.0 . 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 1,515 lbs ( 6.76 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 100 .
