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 47 . 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 . Tabulated values represent the total allowable load on a pair of base connectors . Connectors must be installed in pairs . 6 . Tabulated values are for base connector only . Design professional is responsible for checking concrete and fastener strength . 7 . See Figure 19 .
