13 Ιουν 2015 · An I or a C-Channel? I want to get an understanding from engineering as well as manufacturing (if possible). For engineering (considering bending), I calculated some basic geometric properties like Area Moment of Inertia and Area of Cross-section taking arbitrary dimensions for both shapes. Both the area & MI (Ixx) turned out to be same.
23 Νοε 2019 · I agreed with you that the C channel at upright position will have lower bending stress due to the high inertia of moment. I tried to use the tool you given in the link. Both option A and B given the same inertia of moment (If I am using it correctly). Hi rb1957, Agreed. It should have limited by the crippling stress at the legs in configuration B.
5 Φεβ 2003 · 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. After thinking about your comment on twist, I'm hoping that the floor sheating will stabilize any twist in the 3" channel.
27 Οκτ 2017 · 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...
15 Αυγ 2010 · I am in desperare need of some guideance. I am trying to design a cantilevered channel that is welded to a base plate that will be bolted to an embedment plate into concrete. I have already completed the wed design, assuming the channel's web weld will take all the shear and the welds on the top of the flange will take any forces from the moment.
9 Φεβ 2011 · I have a client who wants to put a hole through the web of my c-channel beam. I am aware of AISC Design Guide 2, but it restricts its guidance to I shaped sections. Anybody know where I can go to for design guidance on c-channels with web openings? ===== David Reber
31 Οκτ 2002 · I am currently punching holes of 0.5" in c-channels C3 and C4. At every 6 inches I need to punch hole on a full lenght of 20'. I currently punching the first hole, after that I manually pull the c-channel up to a dowel pin that fits in the hole and in the die just to make sure that the increment of 6 inches is fine, then I do the second holes and repeat stept until the end of channel.
9 Ιουλ 2016 · I am trying to come up with a clever way to connect (2) C15X33.9 so that there is at least a 3" gap for insulation. The reason for this is that one channel is exposed and only for aesthetics while the inside channel is structural. The 3" gap is supposed to create a thermal break as required by the energy code.
2 Ιουν 2011 · Once you have placed the plate horizontally on the horses, the channel on top is not nearly as stiff as a heavy plate, so it's really not loaded at all until the a-frames start to buckle and the diagonals get some tension or compression. Okay, the channel flanges get some direct compression, depending on the corner details.
22 Φεβ 2005 · The y distance to the tips of the lower channel increases by the width of the flange less the web thickness less the shift in c.g. First yield, I think, would occur earlier but the plastic modulus would increase, so ultimate strength is slightly greater with the toes pointing down.
