5PHYSICAL & STRUCTURAL PROPERTIESOverviewSteel framing is engineered to take advantage of the physical propertiesof formed steel to provide strength where needed and as needed in theconstruction of buildings. This section provides the basic informationneeded by architects and engineers to make sure the member called for inthe plans will meet the criteria required by the structure.Structural framing general notes.3 Gross properties are based on the cross-section away from webpunchouts. Efective properties are based on knockout/punched sections.LEED ServicesBUILD GREEN with ClarkDietrich Building Systems4 The efective moment of inertia for delection is calculated at a stresswhich results in a section modulus, such that the stress times thesection modulus at that stress is equal to the allowable moment. AISIS100-12 Procedure 1 for serviceability determination has been used.ClarkDietrich Building Systems is an active member of the U.S.Green Building Council and is committed to supplying qualityproducts that are environmentally responsible. We are continuallyworking to develop greener building products and sustainable businesspractices. ClarkDietrich steel framing helps contribute pointstoward LEED certification. For more details contact TechnicalServices at 888-437-3244 or visit www.clarkdietrich.com/LEED.1 Physical properties have been calculated in conformance with AISIS100-12.2 Efective properties of structural framing incorporate the strengthincrease from the cold work of forming as applicable per NASPECSection A7.2.Symbols and terms.The following tables are provided to help architects and engineers design structures that withstand variousforces. Those forces include vertical loads such as weight from overhead, lateral loads such as wind, otherapplied pressure or a combination of those. Such natural forces can result in delection and/or twisting ofcold-formed steel framing members.Key among these tables are the physical and structural properties tables in this next section. The tablesprovide typical data required to make determinations about the suitability of materials for certain intendedpurposes. The data is identiied by commonly used engineering symbols and terms. This legend will help youto understand the symbols and terms used here.Ix (in4): Moment of inertia about the X-X axis, used for DEFLECTIONSx (in3): Section modulus about the X-X axis, used for STRESS & LOADSRx (in): Radius of gyration about the X-X axisIy (in4): Moment of inertia about the Y-Y axisRy (in): Radius of gyration about the Y-Y axis, used for AXIAL LOADSWind load (lbs/sq ft): Forces produced by wind, either direct wind (positive pressure), a vacuum (negativepressure) or those generated by wind whipping around the corners of a building. These forces are usuallycalculated according to the prevailing building code. Wind forces are referred to as transverse loads, areperpendicular to the wall, and cause the wall to delect.Delection: The amount of movement of a system, usually greatest at the midpoint, caused bytransverse loading.L/120: Length (height) of stud, in inches, divided by 120 (short interior wall studs)L/240: Length (height) of stud, in inches, divided by 240 (interior wall studs, exterior siding or EIFS)L/360: Length (height) of stud, in inches, divided by 360 (exterior stucco)L/600: Length (height) of stud, in inches, divided by 600 (exterior brick)L/720: Length (height) of stud, in inches, divided by 720 (exterior brick)Limited delection: A design criteria which speciies the maximum allowable delection for a system (L/240,L/360, L/600, etc.).General table notes.Unless otherwise noted, properties are computed according to the AISI S100-12.Sxe and Mxa for studs are based on the perforated web properties for the standard ClarkDietrich ovalknockout. For tracks, Sxe and Mxa are based on a solid section. Ixe is based on the solid section value forboth studs and track.Axial load (lbs): A vertical force produced by overhead loads, such as loors and roof. Floors and roofscontain both dead loads and live loads, which combine to make up the vertical loading.Header: A joist or beam that spans two or more studs, accepts overhead loads from loors and roof anddistributes the overhead load to the jamb studs supporting the header.Pub.

OverviewWall stud and floor joist section properties.ClarkDietrich cold-formed C-studs, produced to ASTMC955 standards, for axial load-bearing and curtain wallframing are prepunched with knockouts at regular intervals—speciically designed to allow for rapid installation of pipes,electrical conduit and wall bridging.Punchouts/Knockouts.Allows for easy installation of wiring, plumbing and bridging.Standard knockout sizing is 1-1/2" x 4" in members 3-1/2" andwider. Members smaller than 3-1/2" are punched with a3/4" x 4" wide knockout. Custom hole placement is availableupon request.Track section properties.ClarkDietrich structural track is a U-shaped framingcomponent used as top and bottom runners to secure wallstuds. It is produced to ASTM C955 standards, and comesin standard 10' lengths. Structural track is also used as endsupport closures for joists at exterior or foundation walls,head and sill plates of wall openings and solid blocking.Track is normally ordered in corresponding size and gaugeto the wall studs. Longer leg track is used for delectionconditions or to accommodate uneven or inconsistent looror ceiling conditions. ClarkDietrich also ofers custom sizes,lengths and coatings.TrackFlange/legCenter of knockouts are punched 12" from the lead edgewith additional knockouts every 24" o.c.
