The inside corner radius is the maximum of 3/32 – t/2 or 1.5t, truncated after the fourth <br /> decimal place (t = design thickness). Centerline bend radius is calculated by adding half of the design thickness to listed corner radius. <br />General Notes for All Tables <br />General Product Information <br />C.L.C.L. <br />24" Min 10" Min <br />Centerline of Web <br />¾" or 1 ½" Typ <br />4" Typ <br />1. The values in this catalog are based on the North American <br />Specification for the Design of Cold-Formed Steel Structural <br />Members, AISI S100-07 as referenced by 2009 International <br />Building Code (IBC), AISI S100-07 with Supplement S2-10 as <br />referenced by 2012 IBC and AISI S100-12 as referenced by 2015 <br />IBC. <br />2. Where AISI S100 is referenced, it is the North American <br />Specification for the Design of Cold-Formed Steel Structural <br />Members, AISI S100-07 with Supplement S2-10 and AISI S100- <br />12, as applicable with U.S. provisions. <br />3. The structural properties included in this catalog have been <br />computed based on allowable strength design (ASD) method. <br />4. Distortional buckling calculations are based on Kφ = 0. <br />5. The effective moment of inertia for deflection is calculated at <br />a stress that results in a section modulus such that the stress <br />times the section modulus at that stress is equal to the allowable <br />moment. AISI S100 Procedure I for serviceability determination <br />has been used. <br />6. Various sections may be manufactured with yield points of <br />33 or 50 kips per square inch (ksi). The yield point used for <br />calculations is indicated in the tables. <br />7. For sections available in both 33 and 50 ksi, the specifier must <br />clearly indicate which yield point is required. For example: <br />362S162-54 (50 ksi). <br />8. Conditions with loads that exceed the 10 psf limit for nonstructural <br />members require an approved CP60 coating. <br />9. When provided, factory punchouts will be located along the <br />center line of the webs of the stud members and will have a <br />minimum center-to-center spacing of 24". Punchouts for members <br />greater than 2 ½" deep are a maximum of 1 ½" wide x 4 ½" long. <br />Members with depths 2 ½" and smaller are maximum ¾" wide <br />x 4 ½" long. Any configuration or combination of holes that fit <br />within the punchout width and length limitations mentioned above <br />shall be permitted; other punchout configurations and locations <br />not in compliance with limitations listed above must be approved <br />by a design professional. Values herein are based on punchout <br />configuration and location as illustrated below. <br />10. The 10" end distance shown may be altered if calculations are in <br />conformance with code.
