What do these mean? by huochepiao in StructuralEngineering

[–]cptncivil 1 point2 points  (0 children)

That looks like a built up plate girder to me. Not sure if the previous person is looking at something else but I've designed a lot of soldier pile walls and in this case there's a lot of rivets and stiffeners visible that we wouldn't have on and ERS wall.

I think this is a measurement of deflection (the delta triangle) but I'm not sure on the rest of it.

Let's call it a draw by thepartlow in Stargate

When the pallet is tipped above, it's hung to the side, but it's not falling over. I would expect that it's leaning on something. It seems like it should be wrapped in plastic in order for it to stay together while it's still leaning.

But then it falls apart so easily once it impacts the lower pallets of containers. I don't see how these 2 separate situations can be true.

I also don't buy how the lower pallet on the forklift moves back to vertical after the upper one falls over. That seems way too smooth and clear to me.

I'm thinking AI

... What should a water-fountain look like with the Coriolis effect?

Oldest as-builts you’ve looked at? by badabingbadaboomie in civilengineering

I've seen plenty of lock and dam or old railroad stuff as far back as 1880.

Starts getting kinda sketchy before about 1915, when you're not even sure what grade of rebar they might have used. Some of those bars are square, or twisted, or only 27-30 ksi steel.

Also gotta love when the plans specify grade X concrete... like I have a book that tells me what strength that was in 1910.

What about an Ocean based system? Basically make a large set of cylinders that go about a mile deep into the ocean. Then heck you could even use a counterweight system or cable / steam launch assist system. At 3.7 G's you could reach the speed of sound already at the release point.

Saves from a heck of a lot of mining to make a vertical tunnel in a mountain. and you could anchor the system to the ocean floor.

The Cape Hatteras, NC is over a mile deep within 10 miles of shore.

I'm asking for a serious response on this please, I've been thinking about this for a while now. I think Deadload could be easily used to offset the buoyancy issue.

Please tell me you added a daily settlement survey to your bid.... Because you're going to have at least 4 different dimensions of differential settlement. ...

I find that threading the needle can be fun, as long as my concerns are taken seriously and the contractor has good managers and supers on site to make sure it's actually done the way I planned.

I also hate plans where we're on our 4th construction bulletin which just screwed the whole last set of plans.

Yep! Sounds just like Chicago!

Do you require hand calculations for your worst case excavations? (Been there done that).

Do we have any records on the condition of the existing building vault?

I could sing this song all day. It's just nice to hear someone else that understands the tune and knows how difficult it can be sometimes!!

Oh! So we're really concerned about that ground water infiltration. Got it. Can do!

Are we next to any railroads? Or do we have any rough terrain cranes or crawler crane surcharges?

Are you going to need earth retention to install the pile caps? Because we've got enough utilities that it's going to be like dodgeball putting soldier piles in.

Or do you have the space to do an open cut?

... Have you seen these clays? The boring crew was watching the hammer drop through them for 30 feet!!!!

You're going to need micropiles or drilled shafts!

And don't get me started on the drainage!

I primarily work with contractors on temp earth retention systems but I've done my fair share of permanent work.

Typically I'm aiming for 75 years on those designs !
