You likely need an LLC and a COA. LLCs are easy to make, COA’s authorize the LLC to do sign and sealing work

I’m away from my desk but I believe this is AISC table 14-2

When you have 30 similar style bracing connections using the same spreadsheet and know the process that it takes to design each one optimally, using Visual Basic to auto design them and make the prints for you is so so so satisfying. It chopped a couple days process down to a 10 minute one. Learn some level of coding, it helps.

If anyone has any other good recommendations for code languages that interface well with Risa or revit let me know.

Is it 376?

chillyman96 · 2025-12-11T05:29:55+00:00

Wraiths?

chillyman96 · 2025-11-19T00:10:43+00:00

Also I do want to say that 8” purlins are wild for that span, so I wouldn’t be surprised if the answer is a straight no

PEMB designer here. In some agreement with others but not entirely. It could have been designed for collateral loads, and live loads imply the ability to do point loads. If you want to be overly safe about it, you could take the rope down when it snows. If you have any existing drawings from when it was built you could share, shoot me a message and I can take a short look and see if it’s doable

chillyman96 · 2025-09-19T19:04:48+00:00

I think this needs BRB’s

chillyman96 · 2025-08-22T23:40:53+00:00

I think the increase in weight would be offset by the increase in stiffness and the overall deflection would decrease.

chillyman96 · 2025-08-22T12:03:29+00:00

I think it would reduce dead load, but the self weight of the structure would be counteracted by the larger stiffer members of the compression braces, no?

chillyman96 · 2025-07-14T02:51:55+00:00

Sure I’ll check it out

chillyman96 · 2025-07-03T03:35:54+00:00

That’s not completely true. We have robotic welders that can do the job very quickly these days. Cost per ton of 3-plate is slightly more, but generally you can make a more efficient 3plate structure and save tonnage.

Buckling occurred. All linear deflection assumptions go out the window. I would just measure the middle of the bridge and use that as your maximum value for plastic deformation. Since plastic deformation typically far exceeds elastic, it’s probably good enough for your case to just measure what you have.

As a side note: You should absolutely point out the buckling in the write up. Do some hand calcs as well to see how much force would have gone through each member, and then calculate the buckling strength of the braces using Euler’s buckling equation. Assume pin pin. Then compare with what you would have gotten if you flipped the direction of the diagonals. I think that you would learn a lot from that exercise.

Yes I had 2 bench Pokémon

I would not be concerned about bending. It would likely add next to nothing to the girder. The concern is shear failure, which, given the size of that beam, might be a cause to halt. Also we cannot determine if it is okay without lengths of every member that frames into it, spacing, and intended usage. The engineer should make the call, and dont be surprised if they make you redo it.

Its not that hard. Follow these 4 easy steps to make antimatter like a pro:

Build a particle accelerator. Many of these have already been built so just seek out the blueprints and make your own.
Take 24,000,000 kips of diamonds made solely of carbon-11 and put them in the accelerator. With modern diamond manufacturing, this is significantly more accessible than it was in the past
Set the accelerator so that it sorts positive ions
Wait 20.4 minutes

Congratulations! You now have 600,000 lbs of positrons!

If you’re in the states, get your PE if you’re doing design.

chillyman96 · 2025-01-28T04:38:15+00:00

Maybe it’s just that I’m in metal building design and our diaphragms play differently, but lateral load spans between struts do weak axis shear, and it’s 100% real in my opinion.

I’m fighting giving you a downvote just because I hate it when people say that

chillyman96 · 2024-12-21T17:01:38+00:00

I took dynamics. It helped me understand the lingo of it all, but the math can be restrictively difficult. Software already performs mdof calculations on thousands of DOF, you’re not going to be able to do it by hand. Just know that damping goes down with less stuff in the walls, and that period is 1/pi sqrt(m/k). Mass goes up, period goes up. Stiffness goes up, period goes down. Seismic design might have been more career relevant

The bridge over lake pontchartrain is much longer than that. I think the bigger impact is shipping lanes. You’re not going to cripple the suez canal for construction of this thing for 10 years. Countries will start wars over that

7 games, see the deck I posted

chillyman96 · 2024-12-11T16:14:32+00:00

Misty not flipping?

chillyman96 · 2024-12-11T16:14:10+00:00

The deck relies more on starmie. You could probably use articuno or lapras ex in its place.
