SSC Connectors — Steel-to-Steel Allowable Loads

1. Min. fastener quantity and load values — fill all round holes; Max. fastener quantity and load values — fill all round and triangular holes; Outer fastener quantity and load values — see illustrations 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. See Fastening Systems for more information on Simpson Strong-Tie fasteners.
5. See image gallery for alternate screw patterns.

SSC Connectors — Bypass Framing Allowable Loads (lb.)

1. See illustration for fastener placement.
2. Allowable loads are based on anchors installed in minimum 3/16"-thick structural steel with F_y = 36 ksi.
3. Allowable loads based on in-plane loads applied at the centroid of the fasteners to the stud, with no rotational restraint of stud.
4. See Fastening Systems and Direct Fastening for more information on Simpson Strong-Tie fasteners.

SSC Connectors — Headers Allowable Loads

1. Max. fastener quantity and load values—fill all round and triangular holes.
2. Designer is responsible for checking web crippling of the header and reducing allowable loads accordingly.
3. Also applies to box header per illustration.
4. See Fastening Systems for more information on Simpson Strong-Tie fasteners.

Nested Stud and Track

SSC Connectors — Base of Jamb Allowable Loads

1. Allowable loads are based on minimum 33 mil (20 ga.) track for 33 mil (20 ga.) and 43 mil (18 ga.) studs, and minimum 43 mil (18 ga.) track for 54 mil (16 ga.) studs, with one #10 screw into each stud flange.
2. Allowable loads assume adequate torsional bracing is provided. Bracing design is the responsibility of the designer.
3. See illustrations in the image gallery for fastener placement.
4. Designer is responsible for anchorage design.
5. See Fastening Systems for more information on Simpson Strong-Tie fasteners.

Base of Jamb Anchorage Solutions

1. Allowable anchor capacities have been determined using ACI 318-14 Chapter 17 calculations with the minimum concrete compressive strength, f'_c and slab thickness listed. Sand-lightweight concrete is abbreviated as "SLWC" while normal-weight concrete is abbreviated as "NWC".
2. Nominal Embedment Depth/Effective Embedment Depth relationships:
   • 3/8" Titen HD^® in 4" Slab : 2.50" (h_nom) / 1.77" (h_ef)
   • 3/8" Titen HD in 6" Slab or thicker : 3.25" (h_nom) / 2.40" (h_ef)
   • SET-XP^® or AT-XP^® Adhesive with 3/8" F1554 Gr. 36 All-Thread Rod in 6" Slab or thicker : 4.0" (h_nom) = 4"_ef)
3. Edge distances are assumed to be 1.81", 3.0" and 4.0" (1/2 of stud width) as determined for 3 5/8", 6" and 8" studs, respectively.
4. End distances are assumed as 1.5 x Min. Edge Distance in one direction and 'N/A' in the other direction. See installation illustrations in the image gallery.
5. Load values are for a single anchor based on ACI 318-14, condition B, load factors from ACI 318-14 Section 5.3, no supplemental edge reinforcement, Ψc, v = 1.0 for cracked concrete and periodic special inspection. Reference ICC-ES or IAPMO-UES evaluation reports for further information.
6. Load values are based on a short-term temperature range of 150°F and 180°F for SET-XP and AT-XP. Long-term temperature range is assumed to be 110°F for both SET-XP and AT-XP. Dry hole conditions are assumed. Other conditions may be evaluated using Anchor Designer™ Software for ACI 318, ETAG and CSA.
7. Allowable Stress Design (ASD) values were determined by multiplying calculated LRFD capacities by a conversion factor, Alpha (α), of 0.7 for seismic loads and 0.6 for wind loads. ASD values for other load combinations may be determined using alternate conversion factors.
8. Tabulated allowable ASD loads for Wind and Seismic in SDC A&B are based on using wind conversion factors and may be increased by 1.17 for SDC A & B only.
9. Allowable loads have been divided by an Omega (Ω) seismic factor of 2.5 for brittle failure as required by ACI 318-14 Chapter 17.
10. Allowable F₄ load based on loading direction towards the edge of slab.
11. Tabulated capacities are based on maximum allowable anchorage loads only. The capacity of the connection system shall be the minimum of the tabulated value and the allowable load value from the SSC Connectors: Base of Jamb Allowable Load Tables.

Typical SSC Installation

SSC Connectors — Rafters Allowable Loads

1. See illustrations in the image gallery for fastener placement.
2. Allowable loads are based on anchors installed in minimum 3/16"-thick structural steel with F_y = 36 ksi.
3. Allowable loads are based on a 6"-deep member. For deeper members, designer must consider web crippling of the member and reduce loads accordingly.
4. See Fastening Systems and Direct Fastening for more information on Simpson Strong-Tie fasteners.

Typical SSC Installation

SSC Steel Stud Connectors (SSC2.25, MSSC2.25, LSSC4.25 and SSC4.25) — Allowable Loads (lb.)

1. Calculated values are per AISI RP15-2, AISI S-100, or generally accepted industry standards. Shaded values for F₄ are derived from test data. Whenever possible, unshaded F₄ values are based on the maximum calculated value and applicable tested value.
2. The tabulated values do not account for anchorage to the support. Anchor strength must be calculated separately and may reduce the capacity of the connection when compared to the tabulated values.
3. Tabulated values do not include shear, web crippling, buckling, or other local effects in the member. The designer must check member limit states separately.
4. For load combinations that include F₄ and/or F₂ and/or F₃, use an appropriate interaction equation.
5. #10–16 screws shall have P_ss ≥ 1,620 lb. Calculated values are per AISI S-100. Screws must be installed with three (min.) exposed threads.
6. The number of screws is for one clip leg that is attached to the supported stud.
7. For the minimum screw pattern, fill all round holes. For the maximum screw pattern, fill all round and triangle holes. See image gallery for screw patterns.
8. In addition to calculations of net and gross section tension, and screw shear of the clip leg attached to the stud, F₂ values are also calculated for weak-axis bending of the anchored clip leg with the line of bending at the smaller anchor holes. The designer is responsible for calculating pullover, pullout, and tension strength of the anchors, and this may reduce F₂ strength compared to the tabulated values.
9. F₃ values are computed using the plate buckling provisions of AISI RP15-2.
10. For the F₄ calculated values, it's assumed that the connection eccentricity is taken by screws in the supported stud.
11. Service load limits for F₂ and F₃ are not given since there are no generally accepted industry methods available to compute these values. F4 service load limits are based on AISI Research Report RP15-2 for 1/8" deflection or applicable test data.
12. For 50 ksi studs, 68 mil (14 ga.) and thicker, use tabulated values for 54 mil (16 ga.) — 50 ksi studs.
