Abstract
A light gauge steel stud with a web shaped cross-sectional profile. This profile gives the stud the ability to withstand higher axial loads than current industry standard C-channel designs. The web shaped profile also exhibits higher resistance to buckling than current industry standards.
Description
- Light Gauge Cold-Formed Steel Studs are presently in wide use within the world as a replacement to wood studs used in the construction of walls, for both load bearing and non-load bearing applications. Light Gauge Steel Studs are resistant to insects, like termites, and will not decay under environmental adversity, like water damage, if properly coated with G90 or other standard galvanized coatings. They also have a more predictable strength characteristic than wood studs. With the simple cold-formed configuration of standard C-channel stud, where the cross-section is uniform throughout its length, problems can arise if large axial loads are placed on the stud. The resulting compressive load, if the base of the stud is attached to a concrete floor or other incompressible surface, can result in lateral buckling in intermediate locations. The Web-Stud Member reduces this buckling factor due to it's web profile and the ability to withstand higher axial loads than current standard C-channel steel studs using the same gauge of steel.

Claims (5)
1. The web-stud member will support higher vertical axial loads, using the same gauge of steel (FIG. 3), than the current state of the art c-channel light gauge steel studs because of it's web shaped profile (FIGS. 1 and 2).
2. The importance of claim 1 , is that the Web-Stud Member can support the same or similar vertical axial loads by using only approximately 11% more steel at a lighter gauge. This is an improvement over the industry standard C-channel studs at the same or similar load requirements.
3. The ability to attach fasteners into both sides of the Web-Stud member increases the versatility over current state of the art C-channel stud.
4. The importance of claim 3 , is the Web-Stud Member can be used in the construction of shear walls and used as support members in standard roof trusses by allowing fasteners to be attached on both sides of the U-channel mounting track used in shear wall and roof truss designs.
5. The physical dimensions C, F and G of the Web-Stud Member (FIG. 2) can be changed to increase or decrease the total width (FIG. 2-B). The physical dimension A and angles D and E can be change the depth (FIG. 2) of the web member. These change can be used to emulated the industry standard light gauge steel C-channel studs sizes, currently being used by the construction industry.
