SJC Connectors – CFS to CFS Allowable Loads (lb.)

1. Min. fastener quantity and load values — fill all round holes; Max. fastener quantity and load values — fill all round and triangular holes; Inner fastener quantity and load values — see illustration and image gallery for fastener placement.
2. Allowable loads are based on bracing of the members located within 12" of the connection.
3. Maximum allowable load for connector that may not be exceeded when designing custom installations. Designer is responsible for member and fastener design.
4. For 6" and 8" joists, SSC connectors are recommended.
5. See Fastening Systems for more information on Simpson Strong-Tie fasteners.

SJC Connectors – Kicker Allowable Loads (lb.)

1. Loads apply to connectors installed perpendicular or parallel to metal deck flutes, with minimum 33 mil (20 ga.) kicker. No increase allowed for kicker with heavier thickness.
2. Kicker angle is the acute angle measured relative to the horizontal plane of the metal deck.
3. The tabulated value for anchor tension is per anchor. Anchors must be designed for combined shear and tension. Simpson Strong-Tie anchorage solutions are tabulated below. Alternate anchors may be utilized if designed by others.
4. Maximum kicker load and anchorage tension at maximum load determined based on tests.
5. See Fastening Systems for more information on Simpson Strong-Tie fasteners.

SJC and MSJC Kicker Anchorage Solutions

1. The allowable maximum kicker load is the minimum of anchor allowable loads or connector allowable loads per SJC Connectors — Kicker Allowable Loads table above. The anchor allowable loads include checks for anchor shear and tension interaction including the effects of eccentric loading.
2. Allowable loads have been determined using ACI 318-14 Chapter 17 anchorage calculations with the minimum concrete compressive strength, f'_c and slab thickness listed.
3. Strong-Bolt 2 and Titen HD are 3/8"–diameter carbon steel anchor.
4. Concrete over metal deck may be Normal Weight or Sand-Lightweight with f'_c of 3,000 psi minimum and 2.5" minimum slab height above upper flute.
5. Minimum deck flute height is 1 1/2" (distance from top flute to bottom flute). All other anchor installation requirements shall follow ICC-ES ESR-3037 and ICC-ES ESR-2713.
6. Minimum Spacing and Edge distances for bottom of metal deck assemblies shall comply with those required in ICC-ES ESR-3037 for Strong-Bolt 2 anchors and ICC-ES ESR-2713 for Titen HD anchors.
7. Load values are based on ACI 318-14, condition B, load factors from ACI 318-14 Section 5.3, no supplemental edge reinforcement for uncracked concrete, Ψc,v = 1.0 for cracked concrete, and periodic special inspection. Reference ICC-ES ESR-3037 and ICC-ES ESR-2713 for further information.
8. Allowable Stress Design (ASD) values have been determined by multiplying Load Resistance Factor Design (LRFD) values by a conversion factor, Alpha (α), of 0.7 for seismic loads and 0.6 for wind loads. ASD values for other types or load combinations may be determined using alternate conversion factors.
9. Minimum end distance to edge of panel is two times anchor embedment depth.

SJC and SSC Connectors – Soffit Stud Hanger Allowable Loads (lb.)

1. Loads apply to connectors installed perpendicular or parallel to metal deck flutes.
2. Stud member design per designer. Tabulated loads for stud fasteners are based on a minimum stud thickness of 33 mil (20 ga.) with a yield stress of 33 ksi. For 30 mil interior studs with a yield strength of 33 ksi, multiply the tabulated values by 0.9.
3. Anchor design per designer. Note that the SJC requires the symmetrical placement of one anchor on each side of the stud centerline.
4. For the bearing plate option, use Simpson Strong-Tie® BP1/2-3 bearing plates at each 3/8"-diameter anchor. Bearing plates are sold separately.
