Although Allowable Strength Design (ASD) is widely used by designers of Cold-Formed Steel (CFS) construction, some projects require additional connector limit states beyond the typical ASD values that are normally tabulated in our load tables. For example, many Department of Defense (DoD) projects require blast design of exterior wall framing and connections. Such projects may require the LRFD strength or nominal strength for the blast calculations. These limit states required for blast design are located below. Search for the particular product required for blast design to find these capacities.

FCB Supplemental Information
The following FCB supplemental information is given to help Designers with value-engineered solutions for our FCB connectors. Loads are given for fastener patterns other than our standard "min." (fill all round holes) and "max." (fill all round and triangle holes). In addition, the tables give LRFD loads and loads for #10 screws as well as #12 screws.

Supplemental Information for Slide-Clip and Rigid Connector
Table 1: SCB/MSCB Bypass Framing Slide-Clip Connector — Service Load Limits, LRFD Design Strengths and Nominal Strengths
- 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 Table 5 on p. 66.
- Service Load Limit is the load at 1/8" deflection for use in evaluating the performance under service-level loads.
- LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.
- Nominal Strength is defined in AISI S100-07.
Table 2: SCW Head-of-Wall Slide-Clip Connector — Service Load Limits, LRFD Design Strengths and Nominal Strengths
- 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 Table 6 on p. 67.
- Service Load Limit is the load at 1/8" deflection for use in evaluating the performance under service-level loads.
- LRFD Design Strength is the Nominal Strength multiplied by a resistance factor, φ.
- Nominal Strength is defined in AISI S100-07.
