SC Bypass Framing Slide-Clip Connector
Ideal for high-seismic areas, Simpson Strong-Tie® SC connectors are the optimal solution for slide-clip bypass framing. SC clips are often welded to the structure in high-seismic zones, but they also feature anchorage holes so that concrete screws or powder-actuated fasteners can be used to attach the clip to the structure. In addition to anchorage versatility, the SC clips include "No-Equal" stamps at the center of the slots to ensure proper shouldered screw placement. SC connectors are manufactured using heavy-duty 10- and 12-gauge steel to provide exceptional resistance to in-plane seismic load.
Key Features
- The clips come in lengths of 3 1/2", 6" and 8" for use with 3 5/8", 6" and 8" studs, respectively
- The maximum standoff distance is 1" for 3 5/8" studs and 1 1/2" for 6"and 8" studs
- Provides a full 3/4" of both upward and downward deflection
- Embossments in the bend line provide increased strength and stiffness in the F1 and F2 load directions, but are positioned towards the center of the clip so that 1 1/2"-long welds can be applied at the top and bottom of the clip
- Prepunched large-diameter anchor holes accommodate 1/4"-diameter concrete screws like the Simpson Strong-Tie Titen HD®
- Prepunched small-diameter anchor holes accommodate powder-actuated fasteners like the 0.157"-diameter Simpson Strong-Tie PDPAT or the #12 self-drilling Simpson Strong-Tie Strong-Drive® XL Large-Head Metal screw
- Precision-manufactured shouldered screws, provided with SC connectors, are designed to prevent overdriving and to ensure the clip functions properly
Installation
- Use the specified type and number of anchors.
- Use the specified number of XLSH78B1414 #14 shouldered screws (included). Install the screws in the slots adjacent to the "No-Equal" stamps.
- Use one shouldered screw per slot (maximum).

- SC Allowable Connector Loads are also limited by the SC Anchorage Load tables below. Use the minimum tabulated values from the connector and anchorage load tables as applicable.
- See illustration for fastener placement when using only two shouldered screws to the stud.
- Tabulated F1 loads are based on assembly tests with the load through the centerline of stud.Tested failure modes were due to screw pullout; therefore compare F1 against FP calculated per ASCE 7-10 Chapter 13 with aP=1.25 and Rp=1.0.
- F1 loads are based on maximum stand-off distances of 1" or 1 1/2" as shown. Other loads are applicable to a 1" stand-off for SC32 and 1" or 1 1/2" stand-off for SC62 and SC82.
- At the bend line, the gross allowable plastic moment in the F1 load direction for 97 mil (12 ga.) and 118 mil (10 ga.) SC connectors are 395 in.-lb. and 675 in.-lb., respectively.
- At a vertical slot, the net allowable plastic moment in the F1 load direction for 97 mil (12 ga.) and 118 mil (10 ga.) SC connectors are 257 in.-lb. and 439 in.-lb., respectively.

- Allowable anchorage loads are also limited by the SC Connector Load Table above. Use the minimum tabulated values from the connector and anchorage load tables as applicable.
- Allowable loads for Simpson Strong-Tie PDPAT-62KP powder-actuated "tophat" fasteners also apply to alternate fasteners with a minimum shank of 0.157", a minimum head diameter of 0.300", a minimum allowable shear of 410 lb. and allowable tension of 260 lb. for A36 steel, and a minimum allowable shear of 420 lb. and allowable tension of 305 lb. for A572 Gr. 50 or A992 steel per ICC-ES ESR-2138. "Tophat" fasteners are recommended to ensure adequate clamping force and consistent installations.
- For screw fastener installation into steel backed by concrete, predrilling of both the steel and the concrete will be required. For predrilling, use a maximum 3/16" dia. drill bit.

- Allowable anchor capacities have been determined using ACI 318 Appendix D calculations with a minimum concrete compressive strength (f'c) of 3,000 and 4,000 psi in normal-weight concrete. Tabulated values shall be multiplied by a factor (λa) of 0.6 for sand light-weight concrete.
- Edge distance is assumed to be 1 1/2", and end distance is 2 5/8".
- Load values are for group anchors based on ACI 318, condition B, load factors from ACI 318 Section 9.2, no supplement edge reinforcement, Ψc, v = 1.0 for cracked concrete and periodic special inspection.
- Allowable Stress Design (ASD) values were determined by multiplying calculated LRFD capacities by a conversion factor, Alpha (α), of 0.70 for seismic load and 0.6 for wind loads. ASD values for other combinations may be determined using alternate conversion factors.
- Tabulated allowable ASD loads for Wind and Seismic in SDC A and B are based on using wind conversion factors and may be increased by 1.17 for SDC A and B only.
- Design loads shall include the over-strength factor per ASCE7 Section 12.4.3. For fasteners in exterior wall connection systems, Ωo = 1.5 per Table 13.5-1.
- Allowable loads for F1 are based on the governing loading direction which is toward the end of slab.
- For anchor subjected to both tension and shear loads, it shall be designed to satisfy the following:
- For Na / Nall ≤ 0.2, the full allowable load in shear is permitted.
- For Va / Vall ≤ 0.2, the full allowable load in tension is permitted.
- For all other cases: Na / Nall + Va / Vall ≤ 1.2 where:
Na = Applied ASD tension load
Nall = Allowable F2 or F3 load from the SC Allowable Anchorage Loads for Concrete table
Va = Applied ASD shear load
Vall = Allowable F1 load from the SC Allowable Anchorage Loads for Concrete table
- Tabulated allowable loads are based on anchorage only. The capacity of the connection system shall be the minimum of the allowable anchorage load and the SC Allowable Connector Loads.
