1 . Tabulated values are for elevator divider beam applications only . 2 . Tabulated values must be used in conjunction with the stiffness values shown in Table 38 . 3 . Minimum safety factor , Ω , for tabulated values is 2.1 . 4 . Multiply tabulated values by 1.5 to obtain minimum Load and Resistance Factor Design
( LRFD ) values . 5 . See Figure 16 .
