those are not carrage bolts. they are called tension control bolts. they have splines that break off when tightened to a sufficient torque.

[@Studio_Hero]

Thanks for the correction Justin!

That is the most useful sculpture I've ever seen.

[@dannycbe949]

Every structural engineer should have one of these at his office...to explain to contractors ..on how connections are to be made... instead of challenging the fitters ability to read drawings!! Great video!

[@bme6907]

I am a drafter new to steel construction and this helped me under connections quite a lot. Thank you for taking the time to give a 101.

[@anujarora4413]

i do also want to draft the same can you guide me from where to learn drafting of steel structure?

[@otaviosilveira1]

I'm a professor in architecture and engineering courses and I can say this video (or the sculpture) is a master piece.

[@VinhLe-gc8ws]

After about 15 videos, found what I needed!

[@philipmzaonako1219]

An unbelievably informative display. Thanks a lot

[@gedionart9630]

it is explained properly-thanks for taking your time to make this video-It was informative

[@rockandmeatroll]

Have some scrap girders to whack together a outdoor temporary area while building my house, this was ace to see all the options. Welding corner plates I think, thank you.

[@daltonhamblin350]

What a badass display. Thx for the informative video!

[@robertsmith5680]

Great video. Been an ironworker for 15 years and stumbled across your video. Only edit i would make is that you said the bolts were carriage bolts. Ive always heard them called "Tension" or "Torsion" Control bolts (TC Bolts). Theres no square cutout like a carriage bolt would normally have. Just a round hole. The bolt kit traditionally has a washer, lockwasher and nut. After leveling and plumbing the structure a TC gun is put on the nut end that snaps the end of the bolt when the proper torque is achieved. Great video. Definitely should be shown to people who are green

[@Studio_Hero]

Thank you for the insight that you are bringing! Noted and much appreciated.

[@Darnic-Fab]

Nicely done!

5 years of university in a ten minute video.

[@Sameer.K2]

Your bachelor is 5 years? :/

[@barryw9480]

You went to university to learn that. Unfortunate you didn't learn on the job. Took me about a year while getting paid. And it does my head in when its called angle iron. Its steel for crying out loud.

[@cloudedmoon]

Super useful. Thanks!

[@indezarchitects1134]

very good video .. & great concept to impart knowledge .

[@nazmulhassan1838]

thats super cool... thanks for sharing

[@vincentip83]

Awesome piece and awesome explanation

[@vincentip83]

I made it through mechanic engineering without learning that a girder carries other beams. Not really related to my specific field but I'll carry that knowledge with me now until I die!

[@matsmixvlogs]

Wow very educational thanks for this video

[@ahsansiddiqui8019]

Thank you so such for this information

[@Raph0ne]

For you it's only a video but for me it's top Quality content! See? No need for a Hall to learn that!

Thanks for the video. It's such a beautiful structure isn't it

[@Studio_Hero]

Absolutely! You’re welcome.

[@nicog8354]

Awesome! I went to SIU and seen this on campus but I didn't know this educational use behind it. GO SALUKIS :D

Can I install end plate connection beam direct on web plate column by bolted?

[@bearro1000]

Bravo 👏👏👏

[@hazemelafifi]

that's what art should be

[@LightGesture]

I moved in to a house where I'm revisiting this because now its definitely going to be needed. Thanks

[@brandonmason1403]

This is like the Rosetta Stone of steel.

Haha love it

[@nilomyki]

Awesome

[@alexyap7323]

educational!

[@hoaiviet456]

Thanks your Video. Can you tell me where Structural Steel Connection in your video? I hope you can share image that Steel Connection. Thanks you very much.

[@wilsonbrua8691]

Nice prosentation

[@AbuKassimMohdSaleh]

Very good explanation,. Can I weld all the joint instead of using bolt n nut ..

[@Studio_Hero]

Thanks for the question! You’ll want to discuss with a structural engineer for your specific project. There’s a lot of factors to consider. From my understanding, a weld has its strength calculated by its radius and its length. Opting to weld the joint will also create a rigid connection, which will not allow for natural movement (I.e rotational movement). The lack of movement creates internal stresses for the joint and materials to resist (due to expansion and contraction for example). This creates the need to fully commit to designing around resisting movement at this joint rather than designing to allow it. That may involve additional plates to increase rigidity. To do that correctly is beyond me at that point. If someone reading this has more insight, please comment!

[@younas_alt7953]

good

[@videot2053]

We’ve got the same thing at Wyoming

[@markr8604]

What’s the likelihood you have Polycam and an iPhone/ipad with LiDAR? Would be most welcome if you were able to 3D scan this and upload to google docs if possible? I think you would offer amazing value doing so…?

[@Studio_Hero]

That’s an awesome idea. Next opportunity I have to scan and share I will!

[@matthewrehkemper128]

I was always wondering how they got the curves on huge commercial buildings

[@Studio_Hero]

Yeah it’s amazing! Steel beams can be curved too, but often the steel skeleton is a series of short straight members. Some steel designs are finished off with a facade that has a curtain wall with custom fiber cement panels which really allow for some smooth curved geometry!

[@wesshelley5767]

What are the requirements for the bolts that tie the column into the concrete. I heard concrete can rot steel. Are they always galvanized? Coated in something?

[@Studio_Hero]

Hey Wes, it’d be good for a structural engineer or product rep to chime in here, but from what I understand: for exterior applications it would be galvanized, coated, or a material that can handle moisture/ ground contact as well as the materials it would be in contact with (think dielectric union between metals, etc). When trying out a new product or technique, it’s best to consult a product rep and/ or engineer to make sure what’s being specified on a set of plans or installed in the field is going to perform the way it’s intended.

[@wesshelley5767]

@@Studio_Hero Thanks!

[@robm2653]

Very informative, thank you. The spider webs were kind of distracting. Maybe you could clean them off if you remake this video

[@phyngineer]

03:55 is a joint like this as strong as if it would be one beam?

[@Studio_Hero]

I hope someone who is a structural engineer can chime in too, but from my studies I’m under the impression that you can design for it to as strong as you need (increasing plate thickness, length, area, doing both welded and bolted connections, # of bolts, size of bolts are some variables that can determine the strength).

[@Glance852]

R u able to reverse a blueprint w an image?

[@Glance852]

For a cost of course :)

[@frank64409]

I don't see an example of a roofing z-purlin attachment for the roofing.

[@Studio_Hero]

Correct! This structure involves primary elements and arguably secondary elements. Z-purlins and other tertiary elements (I.e. mullions) aren’t really showcased here.

[@josephmarti7886]

Good job they are called splice plates not gussets but good video

[@nestorsong]

we can design and produce it

[@tonyduarte9503]

I don't really know what I'm talking about...but aren't those holes in the beams created in order to "choose" the location and direction of deformation in the event of an earthquake? I do know that during past earthquakes the beam wouldn't deform but would instead destroy the post holding up the entire building -- requiring that entire buildings were torn down when the damage could have been contained to beam deformation on a single floor. Those two holes look like they control deformation in two different ways, both saving the rest of the structure. (Some newer connection types allow replacing the deformed section after an earthquake).

[@Studio_Hero]

Super interesting. I’ve never heard of that before, but I have learned of other methods to mitigate lateral loads from earthquakes. I couldn’t find what you’re referring to, but I did find a handful of articles on holes in steel beams www.quora.com/Why-do-steel-beams-have-holes It’s not to say the method you describe is mutually exclusive. Are you able to share a reference with us?

[@tonyduarte9503]

@@Studio_Hero In the "AISC Prequalified Connection 358-16 and 358s1-18w" (seismic) there is a diagram of a "reduced beam section moment connection" where the top and bottom flanges are reduced/cut in order to make that area more "plastic". It is referred to as a "protected zone" since it must not be further modified in order to focus deformation at that spot. Later that document describes an approved Simpson Strong-Tie with reduced web to focus deformation. Later "slots" cut into a web are described. My overall impression is that a variety of methods are being tried in order to focus deformation - and that this is an area where the code is still evolving and engineering judgment is being allowed (since we won't know until there is another major earthquake which of these various techniques works best). I was watching the San Francisco transit center being erected and I was surprised to see welded beam "hinge and pin" connections being extensively used where there would normally be welded connections.

[@Studio_Hero]

@tonyduarte9503 that’s a rock solid reference! I’d say you know exactly what you’re talking about. The concept you’re describing also reminds me of how automobiles use a crumple zone - designed to deform and absorb energy at the cost of replacing anticipated consumable parts. Really cool stuff, thanks for sharing!

[@toddr.4630]

Awesome, great job 👍, it appears that all methods displayed adhere to the fundamentals of "building the $h#t out of it " 😝✌️
