For those wondering, Vs equation is in section 11.5.4.8 in ACI 318-14

Another thing that is often missed with perforated shear walls is the requirement of 4.3.6.1.3 where it says, "each end of each perforated shear wall SEGMENT shall be designed for a compression force, C, in each segment." So you aren't only designing for a compression chord at the end of the wall, but at the end of each segment.

These videos are awesome

With posts that large, they could have easily created a seat on each side of the post for the beams and still had room for the lateral brace. With direct bearing, a lot of failure modes are eliminated.

I was a framer for 3 months, even my inexperienced ass knows you need to sheath before you go up.

In 2012 I graduated from a power engineering course, took 3.5 years. I had a 4th class license that I upgraded to 3rd class over the years. Every year from 2013 to 2021 I made between $150,000-$195,000. I actually finished high school 1995 and everyone said, “go into computers”. People didn’t know what that meant they just saw computers becoming more popular and common place and knew they had no idea how to use it. I’m glade I didn’t. I’m glade I chose a blue collar job. Way more time off, way more money. That’s how you choose a career. Maximize your income with what you can tolerate that gives you the most time off for yourself to live your life.

But what if I want to do detailed calculations so I'm intimately familiar with various limit states, and not just a button clicker/ cookie cutter engineer.....to bad, we gotta make that profit! Nerd out on your own time! BTW, no pun intended @Kestava, I enjoy watching your videos, appreciate all you do!

Hi, would you please let me know in Example F.2-2A AISC where is the cure for C15x33.9 ?is it a mistake in the solution or am I wrong?

This is less pay than a ups driver and With more liability

You should probably mention note b. on table 12.2-1. You are permitted to subtract 1/2 from the overstrength factor if using flexible diaphragms.

Thank you so much for sharing this great video. Just one question, why did you make 24.5' to the power of 2 when calculating Ha(which would make it 9004lb) ?

Seems like TL= 6 sec, not 16, can you please confirm?

if T0 unit is seconds then why is it equal to 0.2Sd1/SDS? (unitless)

Dude just drop a 3 hour explainer. These 15 minute videos are too short

It’s not exactly the steel I would worry about with that wood beam to post connection, it’s the bearing from the steel onto the wood itself.

Yess love this

Guy wires are also used to resist transverse loading due to wind.

😂😂😂😂

😂😂😂😂

These wires are for folks that dont pay attention while they walk.

This is creepy, but I was walking my dog last night and had this exact thought why this cable existed literally last night when I was walking the dog and then now this video shows up in my feed

So do trees/wood have yield strength or ultimate strength? Where do find such data? Also, are there fatigue strength calculations for wood or is there some kind of "rule of thumb" life/cycle number? Any text book you recommend on wood? Thanks.

That guy wire is not only used in change of direction. You will see them at the end of the line and at every mile on both sides of the pole for the length of the power line.

They are called "guy wires." In this case a "sidewalk guy." This is not uncommon, but not exactly typical. Lateral loads (think: corners) on circuits require guy wires, else the poles (and wires) come down into the street after a few years. Most areas (not all) use the 10% + 2 ft rule. A 40 ft pole goes 6 feet in the ground (40' x .10 = 4' + 2' = 6')

I like your short videos here, keep it on please

The pole theoretically could carry the loading in bending, given that it’s embedded into the ground and can be thought of as a cantilevered beam. But that then causes tension on one side and compression on the other, and why introduce those into your soil. Furthermore, we still have to consider the combined loading in that direction during a wind gust. At that point you’ll need to start checking the bearing capacities of the soil making sure this doesn’t exceed them. Even then, there would still likely be some degree of settlement from the sustained loading in the secondary compression stage. The settlement would cause the pole to rotate and thus start to lean. OR you can just use the tension wire in the dirt like they did here to resist the eccentric loading. Probably the better option lol

the dead load isn't the most important thing, nor percent of the pole in the ground. . not on a wood pole. . you leave an assymmetric load on a wood pole for +10 years and you're going to have a bent pole.

Does a (cooked) spaghetti noodle apply a lateral force in the direction of its concave curvature while lying on the plate?

Aren't W-shapes hot-rolled? I don't think they are built-up using plates welded together as you suggest

Wish my boss would literally spend 5 minutes explaining some of this stuff to me. Thank you so much!

thank you!

My fav Structural Content Creator. Thanks!

Very very helpful sir

Are you people working on cold formed steel?

I love these quick reviews

Let’s go Kestava! Just passed my FE mechanical, now going for PE civil Structural starting study early! 📚 thanks for your videos! 🎉

Since you're make an analogy to deep beam, those 3 nos shear walls should acting as 3 nos pinned support in continuous beam, shouldn't it?

Hi, is file bound book allowed in the exam ?

Can you suggest some specifications while buying laptop for structural engineers

Which code books were broken down by chapter besides the steel manual?

Hire me

You are much better off selling a widget than being a person that thinks for a living.

Do you have a playlist of all your vids using mola?

Thanks for the video? What does jd mean and where did you come up with 0.875d?

New epoxy drill dowel must placed with proper offset pattern.

Just to make sure that I understand it correctly. Is the flexible plywood diaphragm the horizontal element subjected to a wind load of 320lb/ft supported by the shear walls? Thanks in advance for the reply?

I just want to highlight something, in some cases the shear from torsion effect shall be in negative value (wall 4 for example)

Very grateful for all your work! More content like this where you analyze structural conditions! Also, how can I contribute to your channel?

Not mention the thread is stripped. Im not sure what this is but maybe casting a new piece is the way to go.
