Titen HD® Threaded Rod Hanger for Cracked and Uncracked Concrete
Strength Design Values for Titen HD® Rod Hanger in Tension
for Installations in the Lower and Upper Flute of
Normal-Weight or Sand-Lightweight Concrete through Metal Deck1,2,5,6
Figure A – Installation in Concrete Over Metal Deck
- 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.
- Concrete compressive strength shall be 3000 psi minimum. The characteristic pullout resistance for greater compressive strengths shall be increased by multiplying the tabular value by (f'c, specified /3000 psi)0.5.
- For anchors installed in the soffit of sand-lightweight or normal-weight concrete over metal deck floor and roof assemblies, as shown in Figure A, calculation of the concrete breakout strength may be omitted.
- In accordance with ACI 318 Section D.5.3.2, the nominal pullout strength in cracked concrete for anchors installed in the soffit of sand-lightweight or normal-weight-concrete-over-metal-deck floor and roof assemblies Np,deck,cr shall be substituted for Np,cr. Where analysis indicates no cracking at service loads, the normal pullout strength in uncracked concrete Np,deck,uncr shall be substituted for Np,uncr.
- Minimum distance to edge of panel is 2hef .
- The minimum anchor spacing along the flute must be the greater of 3hef or 1.5 times the flute width.
