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.
