1 Minimum safety factor, Ω, for tabulated values is 2.0. 2 Tabulated values in table are given per single beam clamp. Beam clamps are to be installed in pairs, one on each side of beam flange. 3 Multiply tabulated values by 1.5 to obtain minimum Load and Resistance Factor Design
( LRFD) values. 4 The design professional must account for the decoupling of moments when the applied loads do not occur between the pair of beam clamps. 5 See Figure 139.
