SC Bypass Framing Slide-Clip Connector

SC

On This Page

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

Material

  • 50 ksi

Finish

  • Galvanized (G90)

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).

Load Tables

SC Allowable Connector Loads

  1. For additional information, see General Notes and Innovative Solutions for Curtain-Wall Framing.
  2. 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.
  3. See illustration in the image gallery for fastener placement when using only two shouldered screws to the stud.
  4. Tabulated F1 loads are based on assembly tests with the load through the centerline of the 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.
  5. 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.
  6. 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.
  7. 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 260 in.-lb. and 440 in.-lb., respectively.

SC Allowable Anchorage Loads to Steel

  1. For additional information, see General Notes and Innovative Solutions for Curtain-Wall Framing.
  2. 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.
  3. Allowable loads for #12–24 self-drilling screws and PDPAT powder-actuated fasteners are based on installation in minimum 3/16" thick structural steel with Fy = 36 ksi. PDPAT values are also provided for A572 steel. Values listed above may be used where other thicknesses of steel are encountered or other manufacturers are used, provided that the fastener has equal or better tested values. It is the responsibility of the designer to select the proper length fasteners based on the steel thickness installation.
  4. For screw fastener installation into steel backed by concrete, predrilling of both the steel and the concrete is suggested. For predrilling use a maximum 3/16"-diameter drill bit.

Allowable Titen HD® Anchorage Loads into Concrete with SC Clip

  1. Allowable anchor capacities have been determined using ACI 318-14 Chapter 17 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.
  2. Edge distance is assumed to be 1 1/2", and end distance is 2 5/8".
  3. Load values are for group anchors based on ACI 318, condition B, load factors from ACI 318-14 Section 5.3, no supplement edge reinforcement, Ψc, v = 1.0 for cracked concrete and periodic special inspection.
  4. 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.
  5. 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.
  6. 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.
  7. Allowable loads for F1 are based on the governing loading direction which is toward the end of slab.
  8. 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 and 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

  9. 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.
