Concrete Shear Wall Design Example
HTML-код
- Опубликовано: 18 сен 2024
- The design of shear walls is a challenging topic. This video works an example problem for a shear wall design for a shear dominated wall or a squat wall with uniform longitudinal and transverse reinforcement. This will be helpful for design engineers or students that are trying to complete their class projects.

A huge thanks to Hailey Goodale, my director of awesome, for editing this video.
Tyler Ley doing a great service helping to tutor young engineers thank you Tyler
@Tyler Ley... DUDE!!! I canNOT believe it! This channel is amazing!!! I have been dying to learn everything I can learn about concrete. If I could turn back the click a dozen or so years, I'd have been an engineer for sure, and I would have specialized in concrete chemistry and mix design. I have been looking all over the internet, including RUclips for a resource that tells me real science... not just children't stuff, but that also doesn't already assume I have a degree in Chemistry. Thank you so much for making these videos. I'll be binge watching them all shortly!
For those of us followers that aren’t taking your class is there an ebook that you would recommend so that we can learn the basics and terms we need to know to understand what is being done?
As a multiple building owner, looking to pour some concrete, I am finding your series of videos useful and interesting. I have poured a few projects with concrete before, but it turns out I made a lot of mistakes compared with what I have learned since. As a result, I am rather certain that my upcoming projects will last longer and look and work better than my past projects. Thank you for making these videos available. In my next small project, while still from bagged concrete from a store, will be better because of the water to cement ratio trying to keep it .4 water to cement or less (provided I can figure out the cement content, reviewing ACI 211.1 and maybe using a plasticizing admixture), the mixing and attempt air entertainment at about 6% and large void reduction, I plan to use fibers, likely basalt, in addition to better placement of rebar where I can anticipate tension, and of course the curing. I doubt I will get it all perfect, in fact, rather certain, but I will try. I would like my concrete to far outlast me. As a result of what I have learned, I am rather confident that it will turn out better and last longer than it would have without me having viewed your videos. My appreciation of concrete has grown dramatically. Thank you for that.
Pretty cool stuff I’m in undergrad for electrical engineering but I can say concrete in pretty cool
The third Vc calculation should start with 0.6sqrt(f'c) instead of 6sqrt(f'c), per ACI318-14 11.5.4.6, right?
For the second part of the first Vc equation, to my knowledge the formula is Nu(0.8lw)/(4lw) however you seem to have done 0.8 (12) which is your height I presume. Was this a miss print on your end or am I missing something important? Either way though thank you for this video, great help for my design class.
What a great professor!!! thanks for all of your videos
Professor, how did you arrive at the value of 's' - the spacing of transverse reinforcement ? It is not mentioned in the video.
What are the design loads, the shear wall can bear( particularly for a Sky-scrapper)?
It’s been a month since you’ve uploaded a video. I just got the new CRSI manual today. I’m excited. Wish someone would do commentary on the changes ::cough:::
Great video, love that shirt!
Your videos are great! I've learned so much!! can you do a few about retention walls? And tieing rebars for columns and foundations?
ERROR - For the first Vc equation there is an small error. Where the 4(20)12 is in the denominator. The 12 which is a unit conversion is not needed and the numerator of that same part of the equation should be changed to 300(0.8)20*1000. This will get you to the 541kips if you were confused.
Does anyone know where in the code these two Vc equations come from?
ACI 318-71
can somebody help me what if the given problem is in metric system, are the constant multiplier gonna change like in Vc ? thanks
Can you review Boundary Elements for concrete shear walls in seismic design?
Question! Are there any resources out there to learn more about the construction of the border wall and how they’re building it? If not, might be a good topic to cover.
Awesome stuff!
Hi, do you reply to comments or questions? If so I have a question for you
What code are you using? ACI? Euro?
What are your thoughts on diy "air crete" made with foam for diy projects
Excuse me I’m making a concrete pot for succulents.
I’ve made many pots but always got small cracking.
I use 0.45 Water cement ratio and 1 part of sand and 1 part of cement and 1% micro AR fiber by total concrete weight.
Do you have any suggestions to make a perfect pot .thank you very much!
which codes here used ? is it euro code or bs codes?
What if we add all the admixture to the concrete will it be good...
Can you do a structural analysis on the Hard Rock hotel in New Orleans
Hi Tyler, I'm making concrete flower-boxes and I'm wondering what happens if I fill and use them without letting them dry or coating them? They will be filled halfway with water all the time, do they survive at least for five to ten years?
hey buddy thanks so much for this channel, btw can u analitics the data to see what demogs or countries u get the most hits from ? and comment on it ? good stuff.
Do you know about Xypax I need your help! and how Xypax work and how much you use for each yard
By what wizardry do you get a phi factor of 0.85 for shear?
same question as it is 0.75 in case of shear
@@azaanahmad6265 and often 0.6 if it is for seismic and not capacity designed
Your numbers are correct though. Sometimes those two equations will give me values under 2sqrt(f'c), have you been facing such situations?
Your video is inspiring .thank you keep up the good vdo
Oh yeah. This is eXactly what we need in our shop. Some serious PE genius. TNSRsys.com is streaming UHMWPE fiber into concrete and it just keeps getting it. Our tests are 8' wide panels because we want to be able to move them without special highway permits. 8'x25'x0.5' without any steel was fine. We're going to edge lift it now to see how that goes. We've been challenged to try edge lifting a 8'x40'x1' panel. What do you think about that? Crazy, right?
Any hope to see a video on concrete foams?
Hello Sir, your videos are Great... I work in a Ready Mix Concrete company..the largest.. concrete company in my country... I would like to receive some recommendations.. because I am planning to optimize the designs ...
what effect if any would coating a concrete wall and/or slab in resin have?
Structurally I mean, and during the first stages of curing. Basically wondering if I build a concrete underground storm shelter, and coat both the inside and outside of the walls as well as the floor and ceiling would that add any strength and or help prevent cracking?
5:27 did anyone understand that? was that to calculate beta? the c/lw
Why do you use old steal rebar? Is there no composite (firberglass) rebar? I think composite rebars is lighter, easer to put together, and cheaper. [example: pretyzkompozytow.pl/en_pl ]
thanks
I have a company in Utah that restores concrete. Would like to joke more about what I’m repairing. Concrete chemistry. Do you offer online classes?
When are you doing another livestream, @TylerLey
I'm not a concrete designer, but why is rebar always calculated for a vertical and a horizontal but never installed as a triangle or truss shape? it seems like the advantages of trusses would also translate to reinforcement. also, how does dispersed fiber reinforcement play into these calculations? is it just not used because it's hard to predict the distribution?
good question what you are pointing out is a very advanced plastic design of elements concept commonly known as strut and tie method
THIS is the question. We're hoping to change that! TNSRsys.com
I want to contact with you for important design problem how can i contact with you it's private thing if that will be possible send me anyway to contact with you through it thank you so much
Great. Now my engineering mind needs to bing on concrete. Here we go...
What is the best way to contact you?
super from India
Can I call you or email you Tyler? Working on a much better driveway than the market is doing. Need you advice. Will pay you per minute on a phone call.
Private Label $9.99 for the first minute, $4.99 each additional minute. 😂
You should get on Interface App and get him on it too. Simple anonymous billing. That's how I found my first PE.
Teaching theory's on concrete but not working with it for a year in the field is bad practice. Like a Doctor teaching about it but never doing it. Take a year off and get out there and you will see everything different.
You are better call saul
crack-up
It makes more sense to allow all columns take all vertical loads, leaving the shear walls to take its own weight and lateral load
Common sense okay
