Anyone a structual engineer, or know one?

[NoSloCB7]

Hey guys, I was just wondering if anyone was a structural engineer, studying structual engineering, or knows one. I have a technical question in regard to anchor bolt position, in relation to the base plate of a steel building. Let me know guys!!

[olivrooom]

Post your question up. My cousin is a structural engineer and he's gonna chill here for a little bit. I"ll have him respond when he sees this.

[NoSloCB7]

Thats awesome man, I have a picture to go along with the question. Let me upload it real quick. Thanks again man. This will be a huge help to me. You're the man...

[NoSloCB7]

Is there anyway I can send him the pictures along with explination to his email? My computer is a piece of shit and won't let me load the pics properly...

roadtripflip@yahoo.com I'll have him read it as soon as he gets here. Hopefully he'll be able to help you out by tonight

These pictures are from a storage facility I am having built.
As you can see, the base of the support column is half on the steel mounting plate and half on the concrete pillar. I was told by the job supervisor that it would be fine. You can also see in the same pictures that the bolts are cocked in an angle, which only allows a small portion of the nut and washer to make contact with the steel plate. I was also told this was ok. I would love to have the professional opinion of your cousin. Thank you for your time Olive....I appreciate the email address as well. I finally got the pictures to work. But if he would like for me to email them to him, I can do so as well!! Thanks you so much...

Here is a pic of the structure with just the roof on. The pictures above are of the base of the main support beams that hold up the roof...

I'm just a sophmore studying Architecutal Engineering, but I'll give you my opninon.

do you have any other pictures about what the structure actually is? is that holding up the roof or what?

and are the bolts only holding in that metal plate?

It looks fine. over time you might develop some probelms, but it definatly doesn't look too bad.

[NoSloCB7]

Yeah, I'll posts some more pictures.....The coulmn that is sitting on that plate, supports the roof. I'll get the pics so you can see what's up...

[NoSloCB7]

Alrighty....I added a pic of the structure....

so, the pilings you are talking about are the ones that are big in the overall picture right? Just one on each side?

How big are the slabs of concrete that those are anchored to, and is there anything underneath them?

Ideally the pillars would be sitting dead center on the metal plates, and all of the bolts also perpendicular to the plate so that they could be fastened down completely. It looks like they didnt factor in some things when they were assembling it, and it threw them off those couple inches. Now, will it make a difference in the amount of weight they can hold up? No. The only problem i can forsee is when there are winds, it will be much more flimsy of a structure. Because those look like the main supports, if you do those wrong, everything else will have to be moved, and end up w/a half ass job.

[NoSloCB7]

Thats was exactly my point....when I saw the shitty job they did, I mentioned it to the supervisor in charge of the footings...He told my that it didn't matter, but I still had my doubts. When it came time to erect the building and I saw one of the main beams hanging over..I got extremely pissed, but again I was told it was fine. I don't like it to be "fine" I want it to be right, espically after the amount of money that has been put into it. I wanted some professional opinions, prior to contacting a local structural engineer, because I am thinking of taking the footing contractor, and job foreman to court....or do you think I should just leave it alone...

Hey FushigiRES ..

I'm no engineer however, I work with several myself.. and we have buildings that look similar to the images that you've posted.

I'll bring up the site tomorrow morning and present these images to a couple of them. and I'm more then certain
that they'll have their opinion's on what you'll need done, or atleast answers to solidify *any* other questions that you might have.

A Hui Hou !!!

I am a Bachelor Struct. Design, and judging from the pic's the beams-couloms there need to be 3 pivoting points (designed) 1 in the middle of the roof (narrowest point) and 1 on each side where the pillar meets the concrete.

This means that this:


point only needs to lead forces into the ground. the way the baseplate is welded onto the coulom should NOT be a problem. However it doesnt look verry nice.

The coulom doesent need to take any momentum (??) at the base (thats why its narrower at the bottom. Only the horizontal and vertical forces need to be taken care of.


To conclude: No problem/hazard

ill post a sketch to explane it some more

^ werd...

it's not going to make a difference aside from an asthetic one, it should be fine. you dont need to bother taking them to court, it's just a visual probelm..
