1. Minimum safety factor, Ω, for tabulated values is 2.65. 2. Multiply tabulated values by 1.5 to obtain minimum Load and Resistance Factor Design
( LRFD) values. 3. See Figure 36. 4. Tabulated values represent the maximum total allowable load of the connector. The applied load on a single horizontal leg cannot exceed 875 lbs( 3.91 kN).
