Columns & Barrels - Reinforced Column Behavior with Captain Jack Sparrow

[@zachleonard258]

My man!!! Helping out a residential concrete guy with big concrete goals and dreams! Its all so interesting, but learning the rules makes it somewhat second nature in the job. Concrete structures are awesome

[@stephensamuel5453]

Hats off to people who care about knowledge and making it interesting and accessible. Teachers are heroes. Big thanks.

[@George.Coleman]

Tyler please reply, how close to the edge of a 4 inch reinforced concrete slab can I lay brickwork for a 2m tall outbuilding?

[@2lboxtowery]

I am absolutely loving these videos. Been slinging mudd for over 20 years and still trying to learn every day. Perhaps you have one I haven’t found, but would you do a similar video on overhead concrete beams. Such as over garage doors etc. Thank you for your enthusiasm and dedication.

[@BirmDindaeng]

Thanks for an amazing presentation.

[@kurtdietrich5421]

Never thought of that comparison before, but it is. Well explained. Thanks.

[@TylerLey]

Hey thanks!

[@joshatienza4466]

Info such as this is gold.

[@sylvainestinvil512]

Tyler, thanks for your videos. Can you please explain the types of failure when testing concrete cylinders and the practical relationship in column design?

[@TylerLey]

Sylvain - Cylinders and concrete column failure is pretty different. Concrete cylinders are restrained by the pads on the top and the bottom and so that changes how they fail.

[@SayImbaPls]

At 3:37 you can see an optical illusion. Focus on one intersection between a beam and a column, and suddenly every other beam and column intersection appear to have a dark spot, until you fixate on one of them again

[@jackgaydar4158]

Excellent delivery and explanation.

[@TylerLey]

Thanks!!!

[@luisluigiconcretellc9604]

Cone Shaped columns definitely the most rewarding type of columns we enjoy forming, reinforcing and pouring

[@TylerLey]

Sweet! Thanks for the comment. Send pictures!

[@luisluigiconcretellc9604]

@@TylerLey Will do!

[@WojtekA.-bk6fg]

Amazing Video about practical approach for column design. Thank You for that. Jaaarrrggghhh :)

[@miloszivkovic6118]

Its interesting how props keeps existing after failure, thats makes me thinking of bending vertical bars of reinforcement in failure shape and than pour concrete.

[@1voluntaryist]

Love the intro, entertaining and informative! Why do people in tornado alley buy/build conventional residences when they could choose a monolithic dome design that withstands an F5?

[@TylerLey]

Thanks! There are not a lot of contractors that build these type of structures and so I don't think a lot of people know it is an option. Also, domes have some problems as well. I talk about this here: kzbin.info/www/bejne/i2mZpZ-LnquAZ9U

[@davidhirschhorn2960]

Do these pillars require secondary reinforcement with rebar going straight across the barrel? I once saw that it is required in California for retaining the concrete, even if broken up by an earthquake.

[@digifilesonlineshop3977]

the best explanation in youtube!

[@BiPolarBear722]

How do you design with fiberglass rebar?

[@1sttigertiger426]

What is the minimum cover for the rebar in a column? Is it the same as for slabs?

[@ma_khalid655]

Very nice vedio... I've a request, can you plz make a vedio on needle vibrator, imp. Points while compaction, avoid segregation and over-vibration etc... It will be gr8..

[@TylerLey]

Thanks! We are working on research on this. Look for a video before too long. I think you will like it.

[@willbee6785]

Best thing. Go on a medium to large construction site. The concrete ganger (boss labourer) & other labourers & carpenters will tell you a lot of what you need to know. Especially what can go wrong. I wish I could help more by way of talking to you.

[@charlesviner1565]

Thanks for the video 👍new subscriber

[@RobB_VK6ES]

Being a pedant here but the explanation barrel hoops is misleading. Barrels are made up of staves each of which has a belly formed into the edges. Just like an arch, the barrel is designed to be self supporting using the natural elasticity of the wood. As the staves are brought together at the center the ends will have a space. The hoops are there to pull the staves into full contact forming a self supporting and self sealing structure. Any minor irregularities are compensated by the wood swelling from being in contact with a liquid. So a cursory analysis would show any hydro-static forces are actually very minor compared with the compression/tension forces in the bent staves and it is these forces that constrain the barrel. The ease of rolling and steering of a barrel (another misinterpreted attribute) is a serendipitous benefit not the primary driver of the design.

[@kevpatguiriot]

the higher the column the thicker the rebar needs to be?

[@somedude-lc5dy]

do people use non-steel reinforcement for columns? how is that calculated? could the hoops be carbon fiber, for example?

[@TylerLey]

No they don't. If the column cracks then it will fail as I showed in the video. The hoops could be carbon fiber.

[@abhouse24]

Amazingly clear!

[@keithlewis9106]

Question, I dont know if you have a video on this, not engineer, ground support for block wall, rebar , box ? Load support is the ground , but to keep from cracking bars in a box ?

[@TylerLey]

Keith, I don't have a video on this. I would need more information on what you are doing.

[@keithlewis9106]

@@TylerLey , old house, I need to pour a footer to support the block wall. The foot I have cracked, no rebar , so, listening to your videos, I thinking box rebar, the weight is light less one kps per foot , guessing. But, ground and weight plus support, I was thinking square footer with box rebar ?

[@georgemichaels2325]

1% to 8.5% cross sectional is the range. That's why there is so much steel in some columns.

[@تثليث-م7م]

thank u very useful

[@empty_kwfggh3i7ywfihf]

Haha love the intro!

[@TylerLey]

Thank you and thanks for watching!!!

[@wriddhi89]

my favourite column adventure is to figure out ties' arrangements for a 14'x8' furnace pier.. 😅

[@TylerLey]

That is a big one!

[@brijeshbhingradiya304]

Sir, all videos are very useful for me in my study, but I am interesting in steel structure design. Can you help me?

[@douglaspohl1827]

West Seattle Bridge has support columns... currently the road-deck is cracking... WHY? is the question. Undoubtedly there has been excess movement - caused by columns or post tensioning failures or ? See: kzbin.info/www/bejne/Z3avea2OqtyXp8k

[@ronymelko9402]

And we love you!! With concrete!! I never imagined myself as a woman falling in love with concrete!! Of course women and cement concrete are mysterious and so no one can know their real identity even when they know their constituents !! Just love it it that we are mysterious

Wish we had professor like him back in college the only way to learn RCC is the way of Professor Tyler ley

[@TylerLey]

Thank you so much!!!!

[@taylanwilson6740]

earthquake proof reinforcing plz

[@patrickmullane30]

I want to build my house in the Philippines 🇵🇭 to stand in a typhoon but still look like a traditional nipa - thus much structure to support wood bamboo and rattan - next to the ocean. Can you advise us?

[@patrickmullane30]

Of course- they are both- fortified 😂

Did Tyler just cough? :-O

[@TylerLey]

I did! I have allergies. i have been in quarantine for a month!!!!
