Your videos on RC have helped me immensely with PE prep, even with the code changes. You hear this all the time but you are indeed one of the best teachers on RUclips.
You are freaking awesome, I can't remember the last time a video answered all the questions I had exactly as I needed them to be. Thank you so much for this
This will help me to recall the basic manual design procedures.. thanks, i will be watching all your videos... I'm changing my job from site supervision to structural engineer.. upload more videos
many thanks to you sir lee, i hope many more videos would be made about rcd especially working stress method/transformed area method and their designs :)
Hi Structurefree! I have learned a ton of things since I started watching your videos some 2 years ago. However, what I struggle to understand is why do we always need to take the full compressive strength? I mean, in a ductile, tension controlled beam way lesser than the balanced. I mean, that beam which has a very thin reinforcement for instance, (just to exaggerate and emphasize the effect), the compressive stress does not attain 0.85fc. Therefore, if we consider the actual, the value "a" will be greater, therefore the moment capacity is safer. I struggle a bit with the 0.85 fc. Thank you very much! I hope somebody answers this for me, please please cant get it out of my head
I need to ask you if there are any videos about design of concrete slabs with each of its types (ribbed & solid ) , ( one way & two way ) thank you sooooo much Eng . Ahmad Halahla
one question. How can concrete compress in bending, if supports are fixed? Because length of concrete fiber cannot shorten but only elongate when bent. If supports are fixed there should only be tension in beam, tension being highest in one extreme fiber and lowest in other extreme fiber.And what are the assumptions made that allows the compression of concrete? REPLY
Here is a question. In the deflection measurement of simply supported beams it is assumed that displacement measured at supports 1 supposed 2 and the middle span of Reinforced concrete beams are 0.10mm, and 6.8mm respectively. Please calculate the true deflection at the middle span of RC beams
+Patricia Nyadhi I can add that to my list since it really depends on whether you are looking at short term or long term deflections and it also depends on the loading since that will influence the moment of inertia of the section.

Just started this class at my college and look who has all the videos I need to pass the class. Coming in clutch AGAIN. Love you
This is making up for the gaps in what my PE Exam prep course didn't teach me about reinforced beams. Thanks!

Great video! Keep the reinforced concrete series going!

Thank you very much .You are the one who is most giving high contribute to students:))
this man is a legend , big thanks .
I love your accent, really helps me to focus lolz
You are the best
please please please keep making these videos. you are great (y)
thank you for every thing you do to help student like me
This is amazing stuff here, thanks for the great work. keep it up
Thanks! You helped me a lot since I started to subscribe in your videos.
Brayll Torrefiel thank you for subscribing!
you're welcome structurefree !
many thanks to you sir lee, i hope many more videos would be made about rcd especially working stress method/transformed area method and their designs :)
Love the reinforced concrete series! Keep 'em commin'! ;D
Great.Thank you
very useful video.

Can u do videos using the metric system?
wicked videos-thanks
what software do you use to write ......????
Great video man! If beam weight is given, how do I find the ultimate moment (demand)?

great vid
Thanks a lot :) What book do you use as reference bro?
can u show a design of doubly reinforced beam?
i guess my only question would be what Beta1 would be equal to if you dont know what youre beams like
Beta depends on the concrete.
@@structurefree thanks man, i saw the table in aci 318 book, thanks for the response! videos are great

I got the solution
what is area about 2#10 ..and how explain pls
The comment may be a little late but can you show how to calculate the maximum instantaneous deflection of a rc beam.
+Patricia Nyadhi I can add that to my list since it really depends on whether you are looking at short term or long term deflections and it also depends on the loading since that will influence the moment of inertia of the section.
+structurefree that'd be really great.... esp if u start from finding short term and long term loading
Thanx
is this according to canadian or american standards?
+Jennifer Brunet I use the American Concrete Institute 318 building code.
