TORQ-CUT™ Self-Undercutting Anchor for Cracked and Uncracked Concrete

Torq-Cut™ Anchor Tension Strength Design Data1

The information presented in this table is to be used in conjunction with the design criteria of ACI 318 Appendix D, except as modified below.
The tabulated value of φ_sa applies when the load combinations of Section 1605.2.1 of the IBC, or ACI 318 Section 9.2 are used. If the load combinations of ACI 318 Appendix C are used, the appropriate value of φ_sa must be determined in accordance with ACI 318 D.4.5. Torq-Cut™ anchors are ductile steel elements as defined in ACI 318 D.1.
N/A (Not Applicable) denotes that pullout resistance does not need to be considered.
The tabulated value of φ_p applies when the load combinations of Section 1605.2.1 of the IBC, or ACI 318 Section 9.2 are used and the requirements of ACI 318 D.4.4(c) for Condition B are met. If the load combinations of ACI 318 Appendix C are used, appropriate value of φ must be determined in accordance with ACI 318 Section D.4.5(c).
The tabulated value of φ_cb applies when both the load combinations of Section 1605.2.1 of the IBC, or ACI 318 Section 9.2 are used and the requirements of ACI 318 Section D.4.4(c) for Condition B are met. Condition B applies where supplementary reinforcement is not provided. For installations where complying supplementary reinforcement can be verified, the φ_cb factors described in ACI 318 D.4.4 for Condition A are allowed. If the load combinations of ACI 318 Section 9.2 are used and the requirements of ACI 318 Section D.4.4 for Condition A are met, the appropriate value of φ_cb must be determined in accordance with ACI 318 D.4.4(c). If the load combinations of ACI 318 Appendix C are used, the appropriate value of φ_cb must be determined in accordance with ACI 318 D.4.5(c).
For sand-lightweight concrete, in lieu of ACI 318 Section D.3.4, modify the value of concrete breakout strength, N_p,cr, N_p,uncr and N_eq by 0.6. All lightweight concrete is beyond the scope of this table.
Pullout strength applies for 2500 psi ≤ f'_c ≤ 3500 psi concrete. For f'_c > 3500 psi concrete, pullout strength need not be considered since steel controls for concrete strengths greater than 3500 psi.
