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 313. 3 Minimum safety factor, Ω, for tabulated values is 1.67. 4 Multiply tabulated values by 1.5 to obtain minimum Load and Resistance Factor Design( LRFD) values. 5 Tabulated values are for base connector only. Design professional is responsible for checking concrete and fastener strength. 6 See Figure 102.
