Reinforced Concrete Shear Design Example Problem
HTML-код
- Опубликовано: 8 авг 2024
- This video provides an example problem for the shear design of a reinforced concrete beam using the ACI 318 design method. This problem compares a general solution to one that is exact and shows that there is a significant amount of more time and effort that is required to optimize the shear stirrup spacing in a reinforced concrete beam.

You explained more in ~20 minutes than any of my college professors did, more than my test prep for the PE and all else in between.
THANK YOU
Trained in mechanical engr but forced by circumstances to design many civil works, these videos would have made my life so much easier.
Being an electrical engineer, I really appreciate you going through design work for structural analysis of a reinforced concrete beam! Keep up the great work.

Thank you. this helps lots of my questions. I like your method of problem solving.
As a building inspector I love this stuff!
What a great video, you got me on the edge on my chair.
As usual, you make design look easy, 👍👍👍
I review septic tank designs, looking at top slab for 300 psf live load, I'm not an engineer but do understand the process and this video was very helpful to further my understanding, great easy to understand presentation.
Always interesting. Clear explanation.
love your videos! this is what i was looking for
Awesome video!
Good video. I wonder if you would do a new example but considering seismic lateral load and maximum possible moments, thanks!
Thank you!
Thank you.
Awesome
Really like your videos
thanks
This was helpful
It was awesome !!!
Thanks for that amazing explanation! Which types of reinforcement steel can we use for shear stirrups according to the ACI?
It's a shame that i only discovered this channel when i already graduated from engineering.
do you have any videos exploring caternary shaped primary tension steel in a regular rectangular beam and implications on shear
@Tyler Ley can we use the same procedure for vertical u-shaped stirrups?
can you make an updated video to address the changes per aci-318-19 for shear stirrups requirements?
It's often better to make designs consistent throughout and not "over-optimize" because there's always going to be some special cases that throws "perfect" desings over the edge. There is no "standard" use case of a solution. Uneven load distributions and impacts are the norm - someone might think it's a good idea to build a weightlifting gym on a floor and that can result in some interesting loads.
No need to apologize for units.
can this be used in designing column shear?
Where can I get a sheet like the one you used to find out what category you are in with the shear load? A,B, D etc.?
Can I use 8mm at every 6 in c/c right across the beams
loving the similar triangle meme. lmao
Not gonna lie you lost me at about 2:30. It seems like cabin fever is setting in to lol
I want more design and analysis of beam according to ACI.
I wish this video existed 4 years ago.
interesting
You said that there is no bar less than #3 but in the market there is 8mm dia and 6 mm dia and these 2 sizes are typically used for beam stirrupes 🤔🤔🤔
Guarantee someone would use #3’s where they should have used #4’s. Complexity increases the opportunity to induce human error. Not a concrete expert, but have spent over 60 years observing people.
Excellent point
I need this in pdf please 😭😭😭😭
Your point at the end about how optimising the design to minimise steel use can have an overall negative impact on project cost and schedule is what is what software engineers call "premature optimisation".
Good software engineers focus on readable, well-structured code without worrying about how it performs, because computer hardware is cheaper than programmer labour. If the performance isn't acceptable after completion, the code is analysed to determine the sections that are used most frequently so that performance optimisation effort can return the best bang for your dollar.
Bad software engineers focus on making everything run as fast as possible, irregardless of how frequently it is used or how hard it will be for maintenance engineers to understand and modify it.
Are you gettting youtuber to do your PDH?
You save 3 stirrups, but your builder curses you, because now he has to have another part on site to stock and control, plus even more verification that the actual plan is followed. An extra space on site, an extra job for the stock controller, and an extra hour spent measuring per beam to see they are following the plan.
Instead one bar size, one spacing, and less headache before the pour, and no way to mess it up, as you are laying them with a template on a wooden plank instead.
Then you get the cowboy builder, who decides that one every 2 feet is good enough, and sells the rest as scrap metal.
Why Av is twice the area of #4 bars??
Consider the cross section of your beam, and how cracking will occur from shearing. When looking at the cross section, the crack will cross the traverse steel twice (on both sides of your cross section). Therefor when calculating Av, you must consider both legs of your traverse steel which means you must multiply Av by 2. Hope this helps!
@@jarrettshafer5131 Thanks...
Supervising the labor would be a big loss.
that units of measurement sucks to be fair
This is over the head of the lay audience.
e.g. What's axial load?

Ty, if you have prerequisites for these, could you list them in the description?
The part about similar triangles worked though.
