Concrete was a course I struggled in the most during my undergrad. You truly helped me understand this a ton, thank you so much! You make engineering truly easy!
there are million youtubers teaching structural, but u outperform all, i love that u explain the reasons behind each formulas and why its written this way
Hey man, thanks for your videos! Your videos are great and clear. I'm taking a class now for the PE exam and no joke, a question like this they do in like half a page and explain the solution in like 60 seconds so I get so lost.
I'm a hydraulic engineer who works on dams but I also have to review a lot of concrete design work. A lot of the sample problems i see online deal with steel/concrete beams. What are good examples of determine rebar size for concrete walls both retaining either water or soil? I just need pointed in right direction. Thanks
I believe it is the same thing but you design the steel per ft instead of per beam width. There is also rebar spacing max on ACI350 because it is holding liquid.
I have a question: after determining the diameter of the bar you didn't aplay the new effective depth which should be 13.5 in.why do you stick with the assumed one.
because the d he used was conservative (assuming the bar is 1" dia.). So the actual d is actually more. No need to fix the d when phi Mn is already OK. If it is barely failing, then maybe go back and refine the calc.
In short, you now have two tension forces, one at the lower row of steel and one at the higher row of steel. both need to be calculated. I will add a video with an example problem Rudy!

You are an excellent teacher and have a way of making it all seem simple.
Thank you! 😃trying my best to keep getting better

glad I can help! always trying to be more clear for people studying / learning!
What a god man! This video is more helpful than my txtbook amd professor combined…..
yo da man Aaron!
the part of how to determine the diameter of the bars to use is not clear to me...can u pliz give more guidence on that
Great 👍
Thank you 👍
hi could you help me with a question similar to this
Absolutely! what do you need?

What if two rows of steel? Or three rows? How to do it?

@@Kestava_Engineering thanks man, appreciate!
