Development length example problem for straight and hooked bars for reinforced concrete

This video presents a development length example problem for straight and hooked bars for reinforced concrete by using ACI 318 building code. The development length equations are presented as well as a number of useful design examples for both hooked and straight bars. This video can help you with your homework or your structural designs.

I love the passion, great video for understanding development lengths

[@shahrzadrahgozar9801]

Wow, I love your energy, I love your teaching style. you explain all the details. I have exam in one week and this helped me a lot. I wish if you could do another example with factor not equal to 1 for hook.

[@silvabkenny]

Great explanation. Thank you very much. Greetings from Venezuela.

[@warlogarcia0824]

i don't understand if it is clear spacing or edge to edge of the reinforcements then why are you calculating it from the center of the rebar.

[@keshavdev]

Great work sir

[@TylerLey]

Thank you!!

[@herysrivera258]

If Possible can someone provide the link to the "bend radius" explanation

[@jichunqin1990]

Just wonder if you could shed some lights on this? In your second example, why the 19in is measured from the edge of the vertical rebar rather than the edge of the concrete?

[@politicalidiot2356]

Very nice

[@TylerLey]

Thank you for the compliment.

[@muhammadazeemkhan1762]

Can you do a video on mechanical anchorage

[@muhamadadammalik4980]

can i have a question? whats the difference between development in table 25.3.1. (ACI 318-14) and the calculation 25.4. (ACI 318-14) thank you

[@naurthy]

Please link the bend radius

[@lemuelalfernandez4305]

why your lambda is in numerator. ACI 318-14 25.4.2.3 shows it on denominator

[@abdulmoreno2551]

sir, where is the link for that bend radii?

[@thewraithvergehexen5974]

And if you have a continuous span with straight bars over Column C2 (C2 column section size could be less than 19inches?), thank you C1--------------------------------------------------------C2---------------------------

[@umgamerff3414]

Sir can we use straight and hooked bars in the same structure If so then what will be the implications of that on that vary structure And also could you plz make a video on different kinds of rebars used in civil engineering world

[@TylerLey]

Yes you can. There is no impact as long as you have a long enough embedment. These two videos cover a lot of them: epoxy, stainless, galvanized: kzbin.info/www/bejne/roenqmtqp7dokJo and FRP here: kzbin.info/www/bejne/qpm4i3yjirmNpJI

[@lemuelalfernandez4305]

What if your Ldh is bigger than your wall thickness

[@fredbloggs2587]

I wish you would take a few seconds to more basically explain the definition as you cover each sub-topic. "A development length can be defined as the amount of reinforcement(bar) length needed to be embedded or projected into the column to establish the desired bond strength between the concrete and steel (or any other two types of material)." What defines the "desired bond strength?"

[@evanosburn718]

Maybe you, bro. I've never had any problems with length

[@ehsnils]

For people in Europe then it would be necessary to go metric instead. The rebar size numbers don't really say anything, but a diameter in millimeters would.

[@joshl90]

Rebar is in 1/8th inch increments

[@ehsnils]

@@joshl90 Unless you are in Europe, then it's metric.

[@joshl90]

@@ehsnils you said that the rebar numbers don’t say anything and that isn’t true, it is a diameter

Music is distracting me to focus on the example problem :(

[@danielsestina6457]

Bending #11 bars; no joke.

[@TylerLey]

Truth!!! Let the machines do it.
