L-3 Communications. CheckerRon (Mechanical) 30 Aug 06 15:02. The Bible for structural steel is the AISC (American Institute of Steel Constuction) Handbook. It defines exactly how to specify various steel shapes, Wide flange, light, and I- Beams, Channels, Angles, Tees. Beams and channels are normally specified by depth and weight (per foot) e.g ...
From time to time we use a 3/4" wide channel iron with 1/2" square holes punched thru the top of it every 4". I need to model this but with a 17 degree bend that is 6" from the end. Can I use the sheet metal bends command for this? Thanks, mncad
Hi guys, I am designing a base structural member in solid works that is a rectangular shaped C channel base With 2 strips of Angle Iron going across them. Solid works smallest standard size for a structural C channel is 3x5. I need to drop it by a few more inches and get the height to about 2 inches but that will result in a custom part that ...
The load will be distributed over approximately 1/2 of the internal width of the channel. The load I am picking will be at the top at both ends, also in the center of the channel width and distributed over about 1/2 of the total channel width. I will be using a beam with calculated deflection ~50% of the 1/240th of the beam length (I have read ...
17 Oct 01 12:05. In my experience, elevator support design forces (hoist beam, guide rail, pit slab, etc.) are sometimes difficult to obtain during the design phase. Some elevator suppliers do not want to give out this information before they have a contract to supply the elevator. That leaves the structural engineer with the option of making ...
t = Member thickness. J = Torsion constant = (bt^3)/3 for b/1 >= 10. or. For a hollow section: Tau = M/ (2At) where A = Area enclosed by the centre line of the hollow section = (b-t) (d-t) HOWEVER the torsional effects on an "open" section are more complex those for a solid bar or a closed section (such as a hollow structural section).

The 3"-4.1 channel would be used as intermediate supports for the floor of the trailer, spanning the 78" dimension on 18" centers. The ends of the 3" channel would be welded to the flat 5" face of the 5" channel. The actual floor surface would be 12ga or 14ga steel, welded to the frame.
Apr 15, 2005. 15,597. CA. surely the difference between legs up or legs down is that in one config the base is in tension and in the other it is in compression. The base in compression will have a higher allowable than the legs and it'll have a lower stress than the tips of the legs (the NA is closer to the base).
I am trying to find a good formula for Warping Constant for C channel sections. This formula will be used in conjunction with AISC 360-10 section F2. In another thread (thread723-206373) I saw a reference to xcalcs.com where a formula is given along with sample results.
