Reinforced Concrete Shear Design Example Problem

[@dannyneufeld2382]

You explained more in ~20 minutes than any of my college professors did, more than my test prep for the PE and all else in between. THANK YOU

[@andrewcliffe4753]

Trained in mechanical engr but forced by circumstances to design many civil works, these videos would have made my life so much easier.

[@stanleysiewierski]

Being an electrical engineer, I really appreciate you going through design work for structural analysis of a reinforced concrete beam! Keep up the great work.

حقا... انت انسان رائع، اشكرك لمشاركتك هذه المعلومات بشكل مشوق. احب ان اتابع جميع حلقاتك، واستمتع بتكرار مشاهدة نفس الحلقة احيانا لما فيها من فائدة اشكرك مجددا

[@tuffdivelife358]

As a building inspector I love this stuff!

[@ferminulit5360]

Thank you. this helps lots of my questions. I like your method of problem solving.

[@TheDonvela]

What a great video, you got me on the edge on my chair.

[@saadhadi1274]

As usual, you make design look easy, 👍👍👍

[@shrekfive5034]

It's a shame that i only discovered this channel when i already graduated from engineering.

[@mgbroussard]

I review septic tank designs, looking at top slab for 300 psf live load, I'm not an engineer but do understand the process and this video was very helpful to further my understanding, great easy to understand presentation.

[@brandonxu5982]

can you make an updated video to address the changes per aci-318-19 for shear stirrups requirements?

[@kevincruz2233]

Good video. I wonder if you would do a new example but considering seismic lateral load and maximum possible moments, thanks!

[@kurtdietrich5421]

Always interesting. Clear explanation.

[@effectprojectekb]

Thanks for that amazing explanation! Which types of reinforcement steel can we use for shear stirrups according to the ACI?

[@ehsnils]

It's often better to make designs consistent throughout and not "over-optimize" because there's always going to be some special cases that throws "perfect" desings over the edge. There is no "standard" use case of a solution. Uneven load distributions and impacts are the norm - someone might think it's a good idea to build a weightlifting gym on a floor and that can result in some interesting loads.

[@DailyMustafa]

Thank you.

[@Wild_Bill57]

Guarantee someone would use #3’s where they should have used #4’s. Complexity increases the opportunity to induce human error. Not a concrete expert, but have spent over 60 years observing people.

[@scorpio6587]

Excellent point

[@Omer-xy7bx]

love your videos! this is what i was looking for

[@dontransue9843]

Where can I get a sheet like the one you used to find out what category you are in with the shear load? A,B, D etc.?

[@bradcavanagh3092]

Your point at the end about how optimising the design to minimise steel use can have an overall negative impact on project cost and schedule is what is what software engineers call "premature optimisation". Good software engineers focus on readable, well-structured code without worrying about how it performs, because computer hardware is cheaper than programmer labour. If the performance isn't acceptable after completion, the code is analysed to determine the sections that are used most frequently so that performance optimisation effort can return the best bang for your dollar. Bad software engineers focus on making everything run as fast as possible, irregardless of how frequently it is used or how hard it will be for maintenance engineers to understand and modify it.

[@dallasduncan3281]

Awesome video!

[@vincentpereira8416]

Can I use 8mm at every 6 in c/c right across the beams

[@Mrbmg07]

@Tyler Ley can we use the same procedure for vertical u-shaped stirrups?

[@Nairuulagch]

Thank you!

[@umgamerff3414]

Awesome Really like your videos

[@scorpio6587]

No need to apologize for units.

[@saadhadi1274]

You said that there is no bar less than #3 but in the market there is 8mm dia and 6 mm dia and these 2 sizes are typically used for beam stirrupes 🤔🤔🤔

[@Johnny-pz3ch]

can this be used in designing column shear?

[@magaracollins9013]

This was helpful

[@shahidulislamshumon4383]

I want more design and analysis of beam according to ACI.

[@nickrielodeontv297]

thanks

[@carlosefrenjaramilloaguayo165]

I wish this video existed 4 years ago.

[@aminafshari7344]

It was awesome !!!

[@SeanBZA]

You save 3 stirrups, but your builder curses you, because now he has to have another part on site to stock and control, plus even more verification that the actual plan is followed. An extra space on site, an extra job for the stock controller, and an extra hour spent measuring per beam to see they are following the plan. Instead one bar size, one spacing, and less headache before the pour, and no way to mess it up, as you are laying them with a template on a wooden plank instead. Then you get the cowboy builder, who decides that one every 2 feet is good enough, and sells the rest as scrap metal.

[@Droningonuk]

Not gonna lie you lost me at about 2:30. It seems like cabin fever is setting in to lol

[@rachershaimange6130]

I need this in pdf please 😭😭😭😭

[@dhananjoydevnath9419]

Why Av is twice the area of #4 bars??

[@jarrettshafer5131]

Consider the cross section of your beam, and how cracking will occur from shearing. When looking at the cross section, the crack will cross the traverse steel twice (on both sides of your cross section). Therefor when calculating Av, you must consider both legs of your traverse steel which means you must multiply Av by 2. Hope this helps!

[@dhananjoydevnath9419]

@@jarrettshafer5131 Thanks...

[@zerjohnalfonso9971]

loving the similar triangle meme. lmao

[@Bibibosh]

Are you gettting youtuber to do your PDH?

[@scorpio6587]

Supervising the labor would be a big loss.

[@hafizsadat7062]

interesting

[@aubreymbewe212]

that units of measurement sucks to be fair

[@hg2.]

This is over the head of the lay audience. e.g. What's axial load? Newbies should start here: kzbin.info/www/bejne/jYe8XnWhbpWsabM Ty, if you have prerequisites for these, could you list them in the description? The part about similar triangles worked though. ..
