Steel: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, G-90 (Z275) hot-dipped galvanized coating. Material thickness = 68mil (14 gauge, 0.0713 design thickness) or 118mil (10 gauge, 0.1242 design thickness). H Plate: Z33, Carbon Steel Class C, ASTM- A 27/A 27M-95, GRADE 65-35 Zinc Plate ASTM-B-633 Type 2 Yellow.
Allowable load tables incorporate eccentric loading of fasteners. Values with welded connection may increase.
When determining the allowable load of fasteners securing StiffClip to the base material and clip to stud, consider the following:
The StiffClip CL product group is produced in three thicknesses (68mil, 118mil, and 118mil(H)) and six stud member depths. The StiffClip CL118(H) utilizes a plate in the 1½ leg. To specify StiffClip CL on drawings, multiply stud depth by 100, followed by the appropriate material thickness, based on strength required.
Example: 6 stud, uplift load of 650lbs.
Designate: StiffClip CL600-68.
StiffClip CL Value
Guide holes for connections to stud and deck
Stiffeners for additional strength
Utilizes only mill-certified, 50ksi steel
Reduces material (replaces heavy steel angles)
M1 = Moment-Carrying
F1 = Lateral
F2 = Horizontal
F3 = Vertical
Stiff Clip CL Anchor Bolt Design
The following equation for tension force in the anchor is derived using the assumed bearing stress distribution shown in the figure to the right. This assumed stress distribution provides a conservative anchor force approximation.
Place StiffClip CL at bottom of stud. Attach clip to deck with approved anchor. Secure clip to stud with required amount of symmetrically placed #12 screw fasteners. If the (H) Piece is used, secure to clip with approved anchor to deck.
