Simpson Strong-Tie has introduced the SCS seismic bypass framing connector, a hybrid seismic clip engineered for either slide-clip or fixed-clip applications in high-seismic areas. This product has undergone full-scale cyclic research testing to determine load capacities in real-world conditions.
To determine the in-plane performance of the SCS clips, Simpson Strong-Tie conducted full-scale cyclic testing on the uniaxial shake table at the Tye Gilb Research Laboratory. The results were used to develop a representative component test to determine various combinations of stud/clip in-plane capacities. The testing allowed them to a re-engineer the bypass clip to increase the in-plane capacity.
Correspondingly, the SCS seismic bypass framing connector doubles allowable in-plane load capacities, resulting in curtain walls that strengthen the overall integrity of a structure and perform better during seismic events.
“Everything about the SCS clip, from its heavy-duty 10- and 12-gauge steel manufacturing to its strategically placed darts to the location of its fastener slots and holes, has been engineered to provide exceptional resistance to in-plane seismicloads,” says Simpson Strong-Tie Senior Product Manager Clifton Melcher, P.E. “Before conducting these tests, there was little understanding of how clips act when subjected to in-plane loads, and the resulting value-engineering has enabled Simpson Strong-Tie to provide a solution that delivers the highest seismic loads in the industry.”
Designed for both slide-clip or fixed-clip applications in areas of high seismic activity, the SCS seismic bypass framing connector is the latest product innovation added to the Simpson Strong-Tie Complete Connector Solution for cold-formed steel (CFS) commercial curtain-wall, mid-rise and residential construction. Engineering and lab testing have enabled Simpson Strong-Tie to deliver CFS application solutions at lower installed costs to customers.
Additional features and benefits of the SCS seismic bypass framing connector include:
- Ribs that provide strength while allowing for ductility.
- Simpson Strong-Tie No-Equal stamps alongside slide slots to indicate proper screw placement.
- A dual-function hybrid clip that includes pre-punched slots for slide applications and round holes for fixed applications.
Slide slots that, when used with shouldered washer screws (included), allow a full 1-inch of vertical deflection.
- Multiple anchor options (¼- or ½-inch concrete screws to concrete, or PAFs or screws to steel).
- Available in 3-½-, 6- and 8-inch lengths.
