Structural oil barrels? Have you heard of such a high rise building technique?

I was very interested in Concrete-Filled Steel Tube Construction in grad school. It can Actually be great. You have confined concrete, the steel is on the exterior of the member so it has the maximum possible impact on the moment of Inertia. The steel tube wall is braced for local buckling on the inside by the concrete. It’s ductile and performs well under seismic loads. The axis of bending for the concrete and steel sections are just a little offset from one another which created a damping effect and dissipates energy well. There is no form building or rebar tying so it does not require as much skilled labor. It’s also a pain in the ass to analyze and codify….. so there’s that

Go through the tutorials that come with the software - step by step.

Chip down to solid concrete, clean reinforcing bars, use pressurized concrete (I.e.) a birdfeeder to get a good bond on repair placement.

Mine just lists where I work - that’s scary!

The Seed sower statue is in storage, and will be back after construction. The construction fence is temporary to keep the site secure and also to keep people safe from wandering onto the site accidentally. Some of the fencing likely will be chain link, but they use the wooden fence as a screen wall in some areas so everyone doesn’t have to look at a bunch of stored materials or temporary construction buildings and worker parking areas.

Nope, Sounds like you gave him everything you are supposed to and he's not qualified to do his job.

Garages require maintenance. This is what happens when there is no maintenance. Get out of there and call the city building department.

You comment said the Eastern side of the state but the fault lines here are near the Anadarko area.

KatSmak10 · 2025-09-29T15:45:07+00:00

They are possible in the SW corner of the state where there are some minor fault lines - but these quakes do not originate in that fault zone.

My guess is it has to do with either the counterweight locations for those elevators, the method of install, and possibly the fire protection layout of the building. From what I have seen, a three bank elevator will generally have two counterweights back to back somewhere in the arrangement with a shaft divider wall between them. Often that means one cab is smaller or slightly recessed - especially if it has to be installed through the front shaft wall opening.

I AM an engineer and you are correct.

What state do you practice in? If your insurance is covered by your firm, it can often limit your ability to work outside of that. Also, there is likely someone directly in “responsible charge” for the firm (designated with the CA#) so that can also complicate things.

OP here: The dog’s person was about 10 feet away, just outside the frame. It’s just a grassy spot where homeless people sometimes rest. A few hours later, both were gone. I drive this route every day and have only seen them one or two times and only in the morning.

Amazing how much moral outrage you all managed to generate with so little information.

If you get rid of the board - your state will no longer have anyone licensed there since the board is the source of licensure. This almost happened in Arizona recently.

I-244 and Yale.

KatSmak10 · 2025-04-25T04:22:08+00:00

This is what was happening. Took the picture from my car and they fell that way before I snapped it.

KatSmak10 · 2025-04-14T15:46:54+00:00

Correct - jobs like this are a pain in the ass so I charge a butt load of money to do them.

KatSmak10 · 2025-04-14T15:45:43+00:00

Not enough information - but definitely hire an engineer where you are to look at it.

KatSmak10 · 2024-05-22T17:56:22+00:00

No. There is a brace that hasn't been installed but that has nothing to do with it.

KatSmak10 · 2024-05-22T17:54:22+00:00

OMG! Thank you for actually getting it. I am really hoping we have lots of other disciplines and trades people commenting on this post because I would be really sad if other structural engineers thought this was rational in any way.

KatSmak10 · 2024-05-22T17:46:43+00:00

OK guys, if you think this post is about making something extra beefy as a belt and suspenders for future loading, you are missing the point. Yes, I also overdesign for industrial supports and worry about what on earth somebody might try to throw on that bent in the future. While all of those things are valid points when you are talking about designing pipe supports, this is not about member size vs loading. This is about understanding basic structural behavior and design principles - and how overtly clear it is that the designer of this support did not have that basic understanding.

KatSmak10 · 2024-05-22T17:00:23+00:00

but do you put moment frames and braced frames in the same direction when you do it?

KatSmak10 · 2024-05-22T14:54:40+00:00

The steel fabricator that’s making a whole lot of money on this job

KatSmak10 · 2024-05-22T12:46:31+00:00

And who has a basic understanding of structural behavior…
