SUBH Bridge Clip Connector — Strength and Stiffness

1. Allowable loads are for use when utilizing Allowable Stress Design methology. For LRFD loads multiply the ASD tabulated values by 1.6.
2. Allowable brace strengths are based on ultimate test load divided by a safety factor. Serviceability limit is not considered, as brace stiffness requirements are given in section C2.3 of AISI S100-2016. Contact Simpson Strong-Tie if nominal brace strength is required.
3. Tabulated stiffness values apply to both ASD and LRFD designs.
4. Allowable loads consider bridging connection only. It is responsibility of the designer to verify the strength and serviceability of the framing members.
5. "Min." fastener quantity and tabulated values — fill round hole (one screw total); "Max." fastener quantity and tabulated values — fill round and triangle holes (two screws total).

LSUBH — Maximum Vertical Spacing for Rows of U-Channel Bridging (ft.)

1. See General Information and Notes.
2. Tabulated solutions are for ASD lateral pressure. Contact Simpson Strong-Tie for LRFD solutions.
3. Lateral pressure shall be determined based on load combinations of the applicable code. For designs in accordance with the 2009 IBC and earlier, wind pressures are at working stress level and may be used directly. For designs in accordance with the 2012 IBC and later, wind pressures are at strength level and must be multiplied by 0.6 for ASD load combinations.
4. "Min." designates a solution with the minimum number of fasteners ((1) #10 screw installed in round hole). "Max." designates a solution requiring the maximum number of fasteners ((2) #10 screws; fill both round and triangle holes). Blank areas designate conditions where the LSUBH does not offer a solution.

How to Use Bridging Connector Allowable Load Table

The tabulated strength and stiffness values are for use with Sections C2.2.1 and C2.3 of the 2016 edition of AISI North American Specification for the Design of Cold-Formed Steel Structural Members (AISI S100-2016) as follows:

Bracing Design for Laterally Loaded C-Studs

• Step 1: Calculate required bracing force for each flange using equation C2.2.1-3
• Step 2: Multiply result by stud depth to obtain torsional moment
• Step 3: Select connector with tabulated allowable torsional moment that exceeds torsional moment from Step 2 for the stud depth and gauge required

Bracing Design for Axially Loaded C-Studs

• Step 1: Calculate required brace strength using equation C2.3-1
• Step 2: Calculate required brace stiffness using equation C2.3-2a
• Step 3: Select connector with tabulated allowable brace strength that exceeds strength from Step 1 and tabulated brace stiffness that exceeds stiffness from Step 2 for the stud depth and gauge required
