1. Introduction. Cold-formed steel members are inherently weak in torsion. If not sufficiently prevented from twisting, large rotations and high torsional warping stresses can occur. Current . I'm trying to calculate the torsional capacity of a 7' long box beam light gage header that has a torque introduced by an eccentric brick veneer. Does it make sense to .Use of cripple stud to receive head/sill tracks at the jamb studs helps maintain alignment of finishes. Strongback header minimizes number of members to be installed vs. back to back or boxed header. Boxed jamb studs welded together reduces material build-up and finish problems. Provides good vertical load transfer at each strongback

Metal stud prices have started to tread downward in June 2024. This might be because lower demand from the construction industry as interest rates increase coupled with developers’ reservations about the election year economy. We’ve experienced a drop in demand domestically and abroad.

Given the advantages that you mentioned did back to back, why do you usually go with box headers? Torsion/LTB? Connections? It really depends on what the metal stud sub wants me to specify. For long spans, the boxed is nice as it has better weak axis strength (if needed) Quote (XR250), I sometimes just specify a single heavy track. Interesting.Torsion boxes involve using a thin layer of sheet goods on both faces, held together by narrow strips of solid wood. They allow you to create thick looking and strong workpieces, but keep the weight down. Torsion box, or "hollow core" projects can be tailored to suit a budget, a look, a finish or a scale. It won't solve your problem with torsion on your header either. My rule of thumb is that when you have a header larger than 15 ft a light gauge box header starts to get pretty heavy and it is usually better to just go with a steel tube. In your case, a 25ft opening is quite large (combined with torsion) and I would definitely use a steel tube. In your sister stud, cut a 1" deep kerf, extend the angle iron from the kerf to the end of your work bench (or get a 36" piece of angle iron, 32 for bench + 1/2 for drywall + 3 1/2 for stud) put these on each stud. Build a torsion box out of 1/2 ply on the bottom and 1/2" mdf on top. Use honeycomb cardboard for the filler, amazingly strong stuff.

I'll have to look it up but I seem to remember a 4 square deep bracket box with KO's is something like .39/ea. Grab a handful of peanut screws from the metal stud "framers" and zip the screws right in. Easy peasy. A torsion box is a furniture guy's term for a structure which gets used all over the place -- airplanes, skis, buildings, etc. It is two fairly thin skins bonded to some lightweight spacer. In buildings, hollow core doors are a good example.

The way to make them totally invisible is by building torsion box shelves. You set steel bars into the wall studs and they extend into the hollow center of the shelves. A bit of construction adhesive at the rear is enough to keep the shelves stuck to the wall. The box bracket grips around the stud and the deep depth allows plenty of room for wiring. I used one single-gang for my heated floor and the extra space was key for the sensor and thermostat wiring. . The 2-Gang Steel .But I'm 95% sure you can get away with just bolting / gluing a few 1/8" x 2" flat steel bars underneath the table top. No need to mess with angle. You'll basically be making 1/2 a steel torsion box, which should be ok because you only need strength in the down direction. I'm guessing that 4 2" wide by 1/8" thick steel strips would be plenty.A steel bar of length L with the cross section shown is twisted through 90º. Determine the smallest ratio L/b for which the maximum shear stress will not exceed 150 MPa. Use G = 80 GPa for steel. The mean dimensions of the cross section of the leading edge and torsion box of an airplane wing can be approximated as shown.

I came to suggest a torsion box too. You get the strength & thickness of a solid slab of wood but at a small portion of the weight & cost. Torsion boxes were the secret to the original floating shelf idea so, if done right, it won't need any legs or knee bashing brackets. A piece of 1/4 x 1 1/2" steel hidden behind the face of the torsion box and screwed to the wooden frame would help keep the face of the shelf rigid, and depending on how much weight you plan on putting up there, would keep the shelf perfectly straight in front, augmenting the 2x2 that is keeping the torsion box straight in back.Torsion boxes refer to flat, sturdy, and fairly lightweight surfaces that, when joined as the bread of a sliced chicken sandwich, are strengthened by the sliced chicken. Of course, we don’t mean sliced chicken literally; rather, we refer to a grid-type construction that the bread attaches to, creating a greater strength than the bread would .A metal stud is ductile and therefore can perform at a wide range of deflections. Wall facing materials tend to be more brittle (Brick, Stucco or EIFS), and thus have a more stringent maximum allowable deflection. . It eliminates box beam headers, stud-to-track nesting, built-up members for posts and jambs and has superior axial strength for .
