For SI: 1 inch = 25.4mm, 1 lbf = 4.45N 1 The tabulated value of Ф applies when the load combinations of Section 1605.2.1 of the IBC, Section 1612.2.1 of the UBC, or ACI 318 Section 9.2 are used as set forth in ACI 318 D.4.4. If the load combinations of Section 1909.2 of the UBC or ACI 318 Appendix C are used, the appropriate value of Ф must be determined in accordance with ACI 318 D.4.5.
