Ever wondered why steel beams have that I-shape?

This is exactly the kind of Shorts video I expected from you guys, loved it!

a 60 sec short basically explained a large part of my "civil engineering structures: intro" course

In addition to limiting lateral/torsional buckling, the I-shape has a much higher moment of inertia, meaning it bends much less under the same amount of weight.

[Anonymouslyme]

More technically, every shape has a Second Moment of Area or Moment of Inertia, which is a measure of how the section’s area is distributed about the shape’s centroid in section. An I beam has a very efficient SMA.

I and U profiles are relatively easy to connect as well. We do not like to weld a lot on site due to quality assurance (only exception being bridges). That is why we use screws to connect beams. Every part of an I or U profile is relatively easy to reach so fitting screws is quite comfortable. Different to e.g. an O profile.

Learning this right now in my university statics course! This short fits the channel well, nice explanation mate!

[nicholastilford]

At one point they were also referred to as “H” beams (more commonly stacked on their sides when on trucks) but we also refer to them as “I” beams because that’s how they’re most commonly diagrammed in manuals.

In short, flange resists the Bending Moment & Web resists the shear force, .. Thats why we use this..

Please do a video on the Gateway Arch in St. Louis!

It ofcourse bends to another direction more easily, than what is portrayed here.

[SuccessforLifester]

Covered this in a course before. Then need to work out things like the summation of forces at a joint to make sure that it is zero without any resultant force

"Why are still beams I-shaped?"

Would love to see a short video regarding the process of how CLT (cross-laminated timber) is made. I think it's a really interesting material, and I've seen a lot of new buildings announced using it so would love to get a better idea of how it works and such.

[Sheik__Yerbouti]

The UB203x133x30 is my dream I beam, closely followed by the UB406x178x85, both in grade S355J0. Chuck in some M24 TC bolts and I’m in UB heaven… Phwoar!

My construction question is when are you going to build your onlyfans website?

[haroldalexis]

It is an interesting question. As a woodworker I have simulated this in some of my projects as well with this I beam design. Amazing science & manufacturing ideas. 💡.

[mintgardener]

How does a building stay straight during construction? How can they go stories up without even getting slanted?

[DavidAhern]

Just remembered castellated i beams from my mechanical engineering days

[milomhoek]

Isn't it because the moment of inertia of the i beam is the one of the highest ones so it has the lowest bending stress?

Your a great teacher i lover your videos they are great!!
