The information presented in this table is to be used in conjunction with the design criteria of ACI 318-19 Chapter 17, <br />ACI 318-14 Chapter 17 or ACI 318-11 Appendix D. <br />The tabulated value of φsa applies when the load combinations of Section 1605.1 of the 2021 IBC, Section 1605.2 of the <br />2018, 2015, 2012, and 2009 IBC, ACI 318-19, ACI 318-14 Section 5.3 or ACI 318-11 Section 9.2 are used. If the load <br />combinations of ACI 318-11 Appendix C are used, the appropriate value of φ must be determined in accordance with <br />ACI 318-11 Section D.4.4. <br />The tabulated value of φcb applies when both the load combinations of Section 1605.1 of the 2021 IBC, Section 1605.2 of the <br />2018, 2015, 2012, and 2009 IBC, ACI 318-19, ACI 318-14 Section 5.3 or ACI 318-11 Section 9.2 are used and the requirements <br />of ACI 318-19 Section 17.5.3, ACI 318-14 Section 17.3.3 (c) or ACI 318-11 Section D.4.3, as applicable, for Condition B are met. <br />If the load combinations of ACI 318-11 Appendix C are used, the appropriate value of φ must be determined in accordance <br />with ACI 318-11 Section D.4.4 for Condition B. <br />The tabulated value of φp applies when both the load combinations of Section 1605.1 of the 2021 IBC, Section 1605.2 of the <br />2018, 2015, 2012, and 2009 IBC, ACI 318-19, ACI 318-14 Section 5.3 or ACI 318-11 Section 9.2 are used and the requirements <br />of ACI 318-19 Section 17.5.3, ACI 318-14 Section 17.3.3 (c) or ACI 318-11 Section D.4.3 (c) for Condition B are met. If the load <br />combinations of ACI 318-11 Appendix C are used, the appropriate value of φ must be determined in accordance with ACI 318-11 <br />Section D.4.4 for Condition B. <br />The characteristic pullout resistance for greater compressive strengths may be increased by multiplying the tabular value by <br />(f'c/2500)0.23 for 1/4" screw anchors. No increase in the characteristic pullout resistance for greater compressive strengths is <br />permitted for 3/16" screw anchors. <br />IBC * <br />1 <br />1821 E Newport Cir <br />12/23/2024
