- 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 3,000 psi minimum.
- 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 Npn,deck,cr shall be substituted for Npn,cr . Where analysis indicates no cracking at service loads, the normal pullout strength in uncracked concrete Npn,deck,uncr shall be substituted for Npn,uncr.
- In accordance with ACI 318 Section D.6.1.2 (c), the shear strength for anchors installed in the soffit of sand-lightweight or normal-weight concrete over metal deck floor and roof assemblies Vst,deck shall be substituted for Vsa.
- Values applicable to both the lower and the upper flute, see Figure A.
- Minimum distance to edge of panel is 2hef.
