I was looking at this as a reference for game development.
We want to make more realistic environments and didn't know the difference between the X Reinforced Sections.
Very nicely explained, and the 3d modelling definitely helps the demonstration!
this was a great refresher. thanks for that!
Thank youuu. Helped me understand better our topic on RC Beams

Excellent way of elaboration!! kindly upload information about doubly reinforcement beam, so we could easily compare strength working. Thanks!!
Wow i love the presentation...I wasn't able to have a clear picture first bcoz I couldn't imagine it..now I have a clear understanding 👍👍👍👍
Happy to know we were able to provide you value🙌
Liked your presentation and animation. Keep up the good work
Thank you🙌
In short, either rebar snaps first or the concrete at the top half of the beam suddenly crush. Ideal case is where the concrete crack becomes visible at the bottom so there is enough time to react, and in the mean time, the rebar holds the cracks
.
Yup that's right. But this is for general case and educational purpose. In practice if the load is high enough, there is no option but go for Over reinforced beam as you can only increase depth to a certain amount.
Very nicely explained! Great video! Thank you
Thank you
I loved it. Good job. Keep posting such
Thank you Sandeep🙌

Thank you Vaibhav 🙌
Great animation detailing brother 👍
Thank you🙌
Nice video it helped me very much thankyou
Amazing work
Thank you Anubhav🙌
Nice explanation
First, in under reinforced section, the failure begins with the yielding of steel before concrete crushing in top chord.
Secondly, in case when the reinforcement ratio is too low, beams might fail due to steel rebar rupture without concrete crushing at top part. These two failure mechanisms are different to over reinforced section which is needed to elaborate.
Your explanation is very good and clean sir
Thank you Satyaprakash 👍
Well explained!!
Thank you Danish
I don’t know why this was in my recommended, I don’t know anything about this stuff and I am terrible at any kind of math. But I watched this anyway because the way you say “concrete” sounds really nice in your accent, and your animations and diagrams actually made these things make sense to me and I know nothing about this stuff, so there’s proof you’ve made a great video if you can make things make sense to a dummy like me! It was very interesting :)
Highly appreciate you watching it. Thank you.
Bhai.. everything u said is correct except the last part @6:01. Strain in steel at failure will be (0.002 + (0.87fy/Es))... Thus steel will fail before concrete crushes for under reinforced section...
amazing explanation. great job!
Thank you 🙌
Thank you sir ✌️❤️
One word for you sir
Fantastic 👍🏻
Thank you Harshit for the appreciation 🙌
Great video! The only point that you brought up in this video that I would contest is that 'overreinforced' concrete beams are more costly, less economical and more dangerous. That is not actually inherently true. Firstly, you might have height restrictions for your beam depending on what you are designing, and therefore must over reinforce the beam. You don't always have the option in real world design to make your concrete section bigger. Also, AASHTO LRFD and ACI specify a reduction factor of 0.65 for concrete beams with 'compression controlled failure', and a 0.9 reduction factor for tension controlled. I don't think it is fair to say that compression controlled failure is 'more dangerous', when you have a stronger section and a lower reduction factor. If you don't believe me, design two beams simultaneously (for same maximum bending), one for compression controlled failure and the other for tension controlled. The computations will prove to you my point on that. Whether one or the other is more or less economical, is completely dependent on what you are designing. That is a common misconception that compression controlled failure is either 'not allowed' or ' inherently less economical'.
I completely agree with you 100%. But I made this for students who are being introduced to this concept for the first time. So for explanation purpose I said you prefer an under reinforced section. But I don't mean to completely disregard the use of over reinforced section, they have their place like you've stated.
I hope this answers the reasoning behind my statement. Thank you for bringing this up, others might also have had this doubt.
@@ReactionTest0 Yes, definitely! I thought this was a great video. Thanks for posting!
how do you get so smart ? I just graduated and all these concepts seem difficult.
A designed height limit wouldnt result in an "over reinforced" beam. if the load requires a certain amount of reinforcement than it will be designed to such specification. an over reinforced beam would mean that it is unnecessarily strong for its intended use.
@@rudolfskrasovskis6790 Correct. Sometimes people use the term 'over reinforced beam' when they mean 'compression controlled failure'. I was simply using the same verbiage that was used in the video for clarity.
Brilliant video
Thank you🙌
Always follow the code rules in regards to steel ratio, do not go beyond the limitations especially with large beams with long spans. Nice video mister.
Thank you Neil 🙌
Nice bro you explained very well and your voice is nice I liked your way of presentation
Thank you so much for the compliment. 🙌 And thank you for watching. Highly appreciate it.
Nice information about sections
Thank you
Good informative video presentation
Thank you
Nice explanation with images. Our teacher don't show the images, don't give any clarity, but you EXPLAINATION is very nice than our teachers thank u so much
Thank you for watching and appreciating the effort. 🙌
Thank U very much sir,,, you are sharing good knowledgeble contents,,, today I learn 1 useful basic,,, thank U sir,,,,
Happy to help🙌
Really a good class for my M.Tech project
Thank you Mohammad
really helpful
U r so under rated bro,but I am pretty sure One day U will succeed 👌
Thank you Dhananjay. It means a lot! 🙌
Thank you so much sir
Graphics is very good. Easy to understand.
Great video man! I will surely recommend your videos to my friends.
One correction- you have to reduce the scale of stress strain curve of concrete with respect to steel.. Because, steel has higher yield stress value compared to concrete.
Thank you Chirdeep🙌
great explanation

I've also released a new video. It talks about the principles which dictate if an object will float or sink in water. Watch it and tell me what you think.
Thank you so much 👍
Thank you Chitralekha🙌
@@ReactionTest0 most welcome
Jo topic teachers se smjh nhi aye ajtk vo ynha smjh agya thank you... But hume Or bhi topics or subjects chahiye the pure plzz upload ❤💯
Thank you Anjali 🤘
very helpful video
Thanks Harsh.🙌
I've released a new video today. Tell me what you think about it
Very nice video. Loved it!! Can you please show how to check if a beam is under-reinforced or over-reinforced at site?
Thank you for that wonderful comment Harsha. There is no non destructive way of checking if a beam is over or under reinforced. You have to check the design of the member to confirm the type of beam design.
Thanks 🙏
Good knowledge
Thank You
Amazing animation
Thank you Anand 🙌
Thanku bhai ❤️
Good information
Thank you Akshay 🙌
how about comparision standard to compare over and balanced ? Eurocode or ACI 318
Very good video
Thank you Rabianoor 🙌
Nice explanation 👍.
Do you use blender for making such beautiful animations ?
Yes, I do use blender.
@@ReactionTest0 Thank you for your response.
When the compression zone is "stronger" than the tension one, I would talk about an overdesigned compression zone, rather than an under reinforced beam.
Similarly when the tension zone is "stronger" than the compression one, I would talk about an underdesigned compression zone.
The reference that has to be taken into consideration is the value that was calculated. From there, if some reinforcement is added, which I would call overreinforcement, the only problem it results in is the additional cost. Not the risk of brittle failure of the compression zone. If this happens, the problem is not the over reinforcement but the under design of the whole.
I agree with what you are saying, but the decision of whether to provide an over or under reinforced beam depends primarily on site conditions and practical restrictions. An under reinforced section is preferred for its lower cost and safety factor(If higher depth beam is available) an over section is chosen when there are depth restrictions.
Hello brother. Like your concept. Can you tell by which software these animation are made. I want to make mechanical videos
Thank you Anwar🙌
The software is called Blender.
And, I've just released a new video. Watch it and tell me what you think about it
Good animation with fluent and nice accent keep making such type of videos

Thank you Priyanka.
Are you asking for SOM lectures?
Great vid. kudos. Which software do you use to create these type of videos, if I may ask? Otherwise keep up the good work
Thank you 🙌. Animations are made with blender. It is sn animation software.
@@ReactionTest0 They are great.
Wonderful explanation.. Kindly tell which sofware used for the graphics and animation?
Thank you. It's a 3D software called Blender.
@@ReactionTest0 great.. Can you please make a tutorial on that how these kind of animations can be made by Blender.. Please its a request... Thanks brother..
