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 41 . 3 . Tabulated values are for elevator divider beam applications only . 4 . Minimum safety factor , Ω , for tabulated values is 2.75 . 5 . Multiply tabulated values by 1.5 to obtain minimum Load and Resistance Factor Design
( LRFD ) values . 6 . See Figure 17 .
