FSB Bypass Framing Fixed-Clip Strut Connector

The FSB connector is the fixed-clip version of our popular SSB slide-clip strut connector. The FSB is commonly used at the bottom flange of a steel beam to accommodate large standoff distances for bypass curtain-wall studs.

Material

• 54 mil (16 ga.)

Finish

• Galvanized (G90)

Installation

• Use the specified type and number of anchors.
• Use the specified type and number of screw fasteners to the stud.
• If the FSB intrudes on interior space, it can be trimmed. The trimmed part shall allow an edge distance of 1/2" or greater from the center of the nearest anchor to the end of the trimmed part.

Load Tables

FSB Allowable Connector Loads (lb.)

1. See General Information and Notes.
2. FSB Allowable Connector Loads are also limited by the FSB Allowable Anchorage Loads table. Use the minimum value from the connector and anchorage load tables as applicable.
3. Min. fasteners quantity and tabulated values — fill round holes; max. fasteners quantity and tabulated values — fill round and triangle holes.
4. Allowable F₁ loads are based on in-plane loads applied to the stud fasteners that are nearest the support with complete rotational restraint at the studs. For more extensive treatment of in-plane loads please refer to Simpson Strong-Tie engineering letter L-CF-CWCF1DIR17.
5. Tabulated F₄ values are controlled by 1/8" deformation limit. The connector strength load in the F₄ direction is 550 lb.

FSB Allowable Anchorage Loads (lb.) Anchorage Type

1. Allowable loads for #12-24 self-drilling screws and PDPT powder-actuated fasteners are based on installation in minimum 3/16" thick structural steel with F_y = 36 ksi. It is the responsibility of the Designer to select the proper length fasteners.
2. Allowable loads for welded connections require E70XX electrodes with a minimum throat size equal to the clip thickness. Welding shall comply with AWS D1.3. Welding galvanized steel may produce harmful fumes; follow proper welding procedures and precautions.
3. Allowable loads are for anchorage only. It is the responsibility of the Designer to verify the strength and stability of the structure for loads imposed by the cold-formed steel framing connections.

FSB Bypass Framing Fixed-Clip Connector — Service Load Limits, LRFD Design Strengths and Nominal Strengths

1. Tabulated values are for the connector and attachment to the stud-wall framing. The assembly strengths are the minimum of those listed and the anchorage values listed in the Anchor Values table below.
2. Service Load Limit is the load at 1/8" deflection for use in evaluating the performance under service-level loads.
3. LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.
4. Nominal Strength is defined in AISI S100-07.

Anchor Values (lb.) in F₁, F₂, F₃, and F₄ Direction for FSB

1. Tabulated values are for the anchorage only. The assembly strengths are the minimum of those listed above and the connector capacity and attachment to the stud-wall framing listed in the FSB Service Load Limits, LRFD Design Strengths and Nominal Strengths table above.
2. LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.
3. Nominal Strength is defined in AISI S100-07.
4. For the Service Load Limit, use the values listed for the connectors in the FSB Service Load Limits, LRFD Design Strengths and Nominal Strengths table above.
