Secrets of Reinforcement | How to design reinforced concrete 

Hey Tyler. I’m a reinforcing rod worker apprentice that just recently finished my level one training. We’ve watched most of your videos in class and they really helped us out a lot .

This is the first construction video that moved me to tears and calmed my fears!

I am 60 year old structural engineer...my teachers never had this kind of passion ... Thanks. 👍

Another terrific video, enjoyed from the UK, thanks prof Ley.

I love how enthusiastic you are about concrete. This is the wonder of the internet. We can get connected to so many people who are so into their niche which gives us quality content like this.

Brilliant. So many fantastically confounding topics covered in one video, abridged comprehensively . Thank you for your enthusiasm and diligence!!!!!!!!!!

The enthusiasm he shares during his videos could make any topic interesting, his subject: concrete. Viv la concrete!

Today I learned something new about RCC ! Thanks mate .

This video is a summary of what teachers are trying to tell in lessons of reinforced concrete, but they cannot. Maybe they do, but not make it fun like you! Thanks a lot! I really enjoyed listening you.- Greetings from Turkey

مش عارف ايش احكيلك بروف... لكنك فهمان وذكي وعندك معرفة كبيرة، وبحب احضر جميع مشاركاتك .. بالتوفيق تيلور

You explain so much better than my lectures. Now i really understand

Hahaha! He was a gardener? Excellant. i have been in horticulture 60 years! And concrete work was a big part of our lives in creating things! In College , i even took a 3 day intensive field class of the properties of concrete. In 1980, there was 2 of us women in that class of 25! That 1 weekend class gave me the science of concrete! As a landscaper & now on small ranch- thar knowledge has helped when i bulit my big corral & horse shelters! Love your channel!

Watching your video should help reenforce our diligence. Also thanks for the history lesson.

that was just what i needed to know! THANKS

nice watch from someone who makes up rebar beams/cages for construction , now i want to see it being used and concrete being poured !

Thanks for this. As an Engineer, this has made me learn more about concrete and reinforcement. Concrete is strong in compression but weak in tension that's the main reason why reinforcement is required. Doing this will eliminate or reduce cracks to be as minimal as possible. Well explained!👍

Love it Tyler. I don't know why I'm so fascinated with concrete, but I am.

OMG! I really love your explanation.

as a UG Trainee engineer this is so helpful

this video is so clear and straightforward, amazing work!!

This bloke really reinforced his point at the end of the video. Thanks mate

Great Content! Watching from Philippines

This is so good! Love the narrating style! And lots of useful info. Thanks!

I always wondered why they put plastic before concreting. Now i understood.thank u tyler

You give me a new love for structure. Im a fresh architecture graduate from Paris. Keep going !

I LOVE HOW ENTHUSIASTIC HE PUTS ON HIS SUBJECT

Love the guy's spirit

Tyler, I think you’re the only person besides myself that gets giddy about concrete construction. I’m not a DIY home owner...oh wait...I guess I am, I just happen to have a General Engineering and General Building license in California for about 40 years. I’m getting ready to design a, my first, post tension sog in northwest MO. I’m so happy 😁 !

We see Prof. Ley’s New Video, We Directly Watch it. You are my new Netflix 😂

Very interactive video indeed......thanks for sharing Monier’s inspiring story

Ur lecture so excited ....i want to know more about concrete properties

You videos are easy to understand and follow. Thank you.

Thank you so much for this information. This will help me with teaching my students about rebar works.

Thanks sir. This is the first video that I have learned from, it changed my mind about reinforced

I'm excited as heck about concrete now.

Much respect for shearing education of construction we need more and more skills

hello from Malaysia. great video! the way you give the explanation surely shows you're a concrete freak, and i love it! keep em coming

Wow..I am going to be a Future Engineer because of you ❤️

excellent teacher u are...from south africa

These videos are pure awesome.... especially the crack sound effects :) haha

I love you dude! You are such a good teacher! Thank you so much for all your hard work and explaining thing so simply so I can actually understand! God bless you bro!

perfect tutorial. thanjs also for talking about our great Mr Monier. you are the best.

I am pouring some footings for a pergola I am making and I put a rebar "cubes" in each one because of your channel.

Thanks Tyler! Complexity broken up into simple concepts & practical solutions. Also, the gray background is perfect.

Why pay for a degree when I can watch this guy

Thank You Professor

You sir are a true Hero. Thank you

Love the passion; absorbing the facts.

Find a metal stamper, the ones who run progressive dies- I ran a stamping plant and would save the skeleton -what is left from a strip of material after the part has been parted from the strip. I used these on several projects around the house, the material was 1/8 - make sure you agitate as the shape is irregular.

Very educative.

Great video Tyler

Very informative. Check your conversion at 6:28. 1,5" is 38mm and not 67mm

Thanks for posting this video. You made it interesting and amusing.

Many you really cheer us up. Great job mate!

In the Philippines they put rebar too close to the outdoor surface and moisture seeps in and corrodes the rebar and the expanding corrosion cracks the concrete. They also lay the rebar on the bottom of the second floor or patio and same story the moisture seeps in and corrosion and cracks and also the rebar isn't doing anything except crumbling and falling on the floor below.

Nice explanations

I'm starting to realize that I'm a total effing NERD. I LOVED this video! Who'd-a-thunk that concrete reinforcement could be so interesting....

Very informative. I work for Tindell. This is a wealth of knowledge to help me have a greater understanding of the mechanics behind my daily labor. #MorePlease

This video was amazing, and the motivational quotes at the end were very appropriate for me in this moment of my professional life. Thanks, Tyler.

Superb Explanation Tyler..I loved it

I read that putting rebar near outer surface of concrete is bad and there should be 1-3" buffer of concrete around any rebar to prevent spalling and protect rebar from moisture/rusting

Another excellent video; well explained. Maybe a demo of a beam cracking with and without reinforcement. Minor point at 08:10 you mention the steel should be 1.5" from the top (67mm) hmm I think it should be (40mm). I only point it out as lot from around the world will see the metric. I see too often builders think the steel mesh should go in the center of the slab for slab on grade/ground. Cheers Pulpo

"Master, I have become the structure."

Build it for life. The cost of rebar at the time of installation is cheap compared to tearing it all apart and redoing it.

As a union carpenter, that does tons of structural concrete, I love this video.

Great job with this video. Taking a deputy inspector course for reinforced concrete now and this is very interesting and helpful.

Hey Tyler, love your work and your personality. My gosh your energy is contagious and fun! Keep up the good work it is fascinating!

I love your style of teaching bro

You should try welded wire mesh. I've done designs with D 12 2 x 8 mesh in multiple layers for pipe design and you should see what happens when you mix it with 60MPa concrete. Unbreakable.

You're a funny teacher, thx for explaining

dude so great information so enjoyable to watch ... keep up !

Superb explanation Tyler..I too am very interested in concrete reinforcement

You're a pro! You've done a wonderful job.

Great explanations and I learned about Monier and his experiments. Your style is unique. I enjoyed the video a lot and I liked it and subscribed to the channel.

Cool informative video.. Subscribed Regards from Egypt ✌️

For basic gravity loads, is easy to grasp tension and compression loads. Add in the dynamics of seismic load and you need to consider different reactions. A basic equation for the seismic load distribution, Ai =1/ αi , is obtained based on the assumption that the velocity spectrum of the ground motion is independent of the period. Further, it is obtained from the maximum shear response using the elastic shear bar with both uniform stiffness and mass distributions. Through lessons learned (and still learning) some structures are designed stiff while others are designed flexible.

Thank you so much

thank You again professor- Unfortunately, have been involved in projects that have so much rebar, there’s little room for the concrete-a lot of lost denver vibrators. I believe that within our industry, we can pretty well predict where it will crack- but sometimes it just “depends”

I loved it and understood every word of it ...thank u dear

I wana talk wire mesh and how i thinknits over rated for residential concrete

Thank you for sharing this video. Just want to share my observation when I was briefly assigned to Saudi Arabia, it's about plastic-coated rebars and tie-wires used (slab) without any sign of rusting even after 20 years. It would be great if there will be pre-cut rebars and plastic-coated for structural, so as to assure no metal exposure to cement.

Intersecting steel rebars that form right angles forming a double-shell reinforcement 1 inch deep below the concrete top surface and 1 inch above the conrete bottom surface. With post tensioning used in bridges that has 2 supporting beam and post supports, then on a slab it should be INTERSECTING LENGHTWISE AND CROSSWISE POST TENSIONING for the supporting beam and post supports are replaced by the EDGES of the slab at the FRONT AND BACK AND LEFT SIDE AND RIGHT SIDE. The the post tensioning should be Intersecting post-tensioning cables that form right angles from the front to the back, and from the right side to the left side. But personally I prefer a double-shell of intersecting steel rebars that form right angles like a square grid pattern. And combine it with double twisted pre-anodized galvanized steel fibers. Forming a very dense hybrid steel rebar-steel fiber reinforced concrete.

I really value seeing your vids.

I have never believed in concrete as much as I do right now!

So much emotion guy, good info @Dextcharles

From Iraq. - thank you sir -- you r great

My grandpa inspired me to become interested in concrete. I heard he was a major engineer for some European country during WW2; he designed some towers that still stand to this day!

Thanks for the great video

Please can you do a video on raft foundation , and please why do we have extra additional layer of reinforcement in a raft foundation

So wonderfull lecture.. need a lecture about plinth beams it will be very helpfull if you provide this on your channel

Awesome info

Curios of reinforcement design. I am building concrete patio, driweway 3m wide. I decided to use rebar with 0.4m spacing, at the bottom and top, so two layers of reinforcement. I think is better solution then add in the middle with 0.2m spacing. Average concrete thickness is 12cm, so either "middle" version has to press 6cm(if perfect in the middle, normally 4-6cm)of concrete to crack or ~8-10cm for two layer design. So I hope I gained double the strength with same materials, just more labor work. Since I do it myself, I don't mind.

It was Julia Morgan who pioneered the use of reinforced concrete.

Plz do the video about basalt fiber n what effect made to mechanical properties using basalt fiber

Please make a video how to protect/insulate roof top concrete from sun heat.

Thankyou for the video. Small mistake there...1.5" is not 67mm right.

Your style of explanation 👍👍

Loved it from India ❤️♥️❤️♥️❤️♥️❤️♥️😍🇮🇳

Remember, you asked for it. I want to build a garage over a basement. The garage floor will cover a free span of 24' x 24'. The top of the garage floor will be flat, the bottom slightly concave. The concavity should make the floor about 3" thinner at the center. I'm all for loading the concrete with macro- and micro-fiber, but am having difficulty justifying using FRP since none of the slab will be in tension. I'm in favor of adding super-plasticizers to reduce the number of large air pockets. I'd prefer the slump to leave the wet mix virtually flat, but that probably falls into the realm of the next hundred years.

The ground does move, so rebar is necessary to account for the soil shrinking/swelling/consolidating causing tension in concrete?
