When I said "top of radius" I had not laid it out. Now that I have it is obvious that would not work.
45 degrees to tangent of the radius is close to what I was envisioning.
I was hoping for some "offical" guidance but I think this is reasonable.
Thanks everybody.
Where on the channel would you consider the "thickness"?
The code specifies to subtract 1/16" from the thickness, but where on the channel would you measure the thickness?
I would not use the flange thickness listed in SCM that dimension is almost half way up the slope.
I would think at the top...
Hello all,
I have a question about the maximum fillet weld that can be applied to the toe of a channel.
Is there guidance on what part of the channel toe should be considered the "top" of welded portion?
Thanks
I wanted to let everyone know about a unit problem with in the calculations of E6-1 in RISA. The input "a", the bolting spacing, is labeled as feet, however I believe the program uses that number as inches in the equation for E6-1. I have made RISA aware of this and they have said there will be...
I am hoping for some clarification/guidance on E6 is AISC. If I understand it correctly E6-1 for snug tight bolted intermediate connectors gives you Lc/r for the built up member. You use this in either E3, E4, or E7 to get your critical stress.
If this is incorrect please let me know.
The...
This is a plan view cut through the column/field joint as I saw it in the field. I want to say the shell plate would not allow rotation. I see the shell as a brace to weak axis Lateral Buckling. While strong axis could use a portion of the shell I probably wouldn't.
I work in industrial equipment. When visiting sites I like to look at the existing equipment. I have seen things I had not thought of and was very impressed by and seen things that made me uneasy to climb on said equipment.
I have seen in the past (when visiting job sites with older equipment) a...
Hello all,
I am new to Caesar II. I have a lot of experience with RISA, I know these two programs are not alike in any way but I was hoping Caesar has some features similar to RISA.
In RISA you can select any portion of nodes, members, plates etc. and hide everything else so that you only...
This answer will not be very helpful I am afraid.
I can't give you a how-to but maybe some places to start reading.
Is this being compared to API560 or STS-1?
There are plenty of older articles written on the design of steel stacks out there for you to read if neither of these are being...
I have a situation where the holes are 1/8" oversized on the diameter instead of 1/16" on vertical diagonal braces, back to back angles.
I have in the back of my head a memory that if only one of the plies were oversized, the connection could be considered a bearing type connection.
In this case...
Thanks for taking the time to help me on this.
I can actually brace the C12 at green dots fairly easily.
So I will do that along with extending the MC10 for a weld that handles the full moment on each side.
thanks again.
As I look at what you are saying it makes sense that the moment is a result of a load, not just a random moment in the center of a beam. if there was a small gap in the weld it would be two "C" shapes of weld on each side,and in order to stay in equilibrium there would have to be equal and...
No I was thinking about a case of a moment applied at the center of a simply supported beam.
I see what you are describing, then the reactions are force/2, the force equally divided between the two supports.
For "M" as a moment in the center of a simply supported beam then R1 = R2 = M/L, but if...
That does make sense, but it still seems to go against the reactions at either end.
The reactions then would be M/(L/2) instead of M/L, I am less arguing than trying to align these two thoughts in my head.
The end plates were in my mind to help transfer the load from the C12 flanges to the MC10 flanges. It might not really work that way but that was my thought process.
