Titen HD® Threaded Rod Hanger for Cracked and Uncracked Concrete
Strength Design Values for Titen HD® Rod Hanger in Tension
for Installations in Concrete1,6
- 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 value of φ applies when the load combinations of ACI 318 Section 9.2 are used. If the load combinations of ACI 318 Appendix C are used, refer to Section D.4.5 to determine the appropriate value of φ. Anchors are considered brittle steel elements.
- Adjust the characteristic pullout resistance for other concrete compressive strengths by multiplying the tabular value by (f 'c,specified / 2500)0.5.
- The value of φ applies when both the load combinations of ACI 318 Section 9.2 are used and the requirements of Section D.4.4(c) for Condition B are met. If the load combinations of ACI 318 Appendix C are used, refer to Section D.4.5 to determine the appropriate value of φ.
- The value of φ applies when both the load combinations of ACI 318 Section 9.2 are used and the requirements of Section D.4.4(c) for Condition B are met. If the load combinations of ACI 318 Section 9.2 are used and the requirements of Section D.4.4(c) for Condition A are met, refer to Section D.4.4 to determine the appropriate value of φ. If the load combinations of ACI 318 Appendix C are used, refer to Section D.4.5 to determine the appropriate value of φ.
- For sand-lightweight concrete, the modification factor for concrete breakout strength must be taken as 0.6. Additionally, the pullout strength Np,uncr, Np,cr and Np.eq must be multiplied by 0.6, as applicable.
- For sand-lightweight concrete, in lieu of ACI 318 Section D.3.4, modify the value of concrete breakout strength, Np,cr, Np,uncr and Neq by 0.6. All-lightweight concrete is beyond the scope of this table.
