hi - I am talking about spacing between longitudinal bars for that check. the check ensures that the concrete and aggregate can fully flow around each bar. hope this helps!
@@Kestava_Engineering Thanks for asking. I got my results and did well on all of the structural afternoon portion but not so well on the breadth (non-structural) sections. I will have to retake it. For those that dont know, in April 2024 the PE Civil structural format will be changing. There are getting rid of the breadth section and the test is going purely structural . There will be a morning vertical section and afternoon lateral section (kind of like the SE). I think I will do much better with the new format. Thanks!
I have a 24’ x 36’ open air carport project that is on a small hillside…I wanted to build the ground level with cement columns, beams and slab. Then a wood post and beam structure with shingle roof. I wanted to space the columns approx 12’ on center. So 12 total columns. For a class project…need to know the size of foundations, columns, beams and slab thickness with size, amount and spacing of rebar and stirrups. Its would make a good tutorial video for your channel. And I can understand the engineering of such a project! Thx. Joe.
Hello, love the problem and thank you for posting this! On table 22.4.2.1-Max axial strength, why did you not use the bottom member item (composite steel and concrete columns in accordance with Chapter 10)? Review for my PE exam.
Rich, thanks for the video. So aci section 25.7.2.1 is specifically dedicated to tie spacing and the very first provision has nothing to do with tie spacing?
Love your videos! Would you be able to go over the process for designing two-way slabs per ACI? I need a good refresher but haven't been able to find one
Aci has one of the most horrible codes. For me 318-14 was a step backward from 318-11. It was hard enough to find stuff in -11 and they made it even more confusing. Btw thanks for the video buddy it helped me to understand
🙏🙏🙏 Preach Samuel sam! The new ACI just dropped and it has color examples in it to help explain the madness. I don't know if they have totally rearranged the chapters or not though. Currently trying to get my hands on the dang thing. I'm glad I'm able to help you understand a bit more. Always let me know what topic you'd like to explore.
@@Kestava_Engineering yeah for sure dude thank, like would you think stirrups and tie spacing requirements would be in the same chapter with their new setup? No, one is in chapter 25 and the other is in the beam specific section. And they’re really terrible about the nested references “Ensure the provisions of 8.6 apply” go to 8.6, must meet requirements of 26.2, 18.3 blah blah just kill me now
I agree with other comments about the poor format of the ACI code. AISC develops a whole manual to make steel design faster and explain things instead of just the specifications, but even the AISC 360 specs are organized, have clear equations and section organization, and tables with illustrations (e.g. slenderness ratios). NDS does the same and the way the Supplements are laid out, ensures easy navigation (not too much flipping). ACI is a mess, even the new one. You have to flip everywhere and basically derive all the useful design equations. It is a scavenger hunt to try and find things.
Hey Kestava Can you do a series on the preliminary design of a building(i.e. placement of columns and preliminary column and beam sizes etc ), prior to do the analysis in STAAD Pro (and how do the iteration if the acceptable deflection is not met is not met in STAAD)????
Great video! I just showed this to my classmate- these videos have helped us SO MUCH! You're a legend
Thank you! Im glad they are a help to you all!
very good lecture , his teaching way with reading ACI code during calculation is very helpful
Glad to hear that!
Thanks!
Casey I just saw this - THANK YOU SO MUCH!!! way to generous!
@16:08, you stated that this is for spacing of your longitudinal bars. But this is for minimum clear spacing between ties.

Thanks! Taking the PE structural in two days!
hope it went well. how did you feel??

Contrata a un ingeniero
IT IS VERY USEFULL AND EXCELLENT WORK I REALY LIKE IT

Good lesson for student and engineer.
Agreed! this one was a great intro column design problem.
Great video as always. For phi, you should have went to table 21.2.2 which would have confirmed 0.65.
love that
Love your videos! Would you be able to go over the process for designing two-way slabs per ACI? I need a good refresher but haven't been able to find one
yes I have that video in the works!
So well put together! Thanks!
thank you Laura! Anything you'd like to see next in particular??

Isn’t #9 too large of a diameter?
You did not talk about min and max area of reinforcement required as per ACI 318.
very true! I left that part out and should include it next time I do concrete! thank you for the catch
Thank you so much

Sir, why did you calculate Amax that you used stirrup with 2*0.375, actually, you have only one stirrup right. It should be 0.375 only
The stirrup is on each side of the column, so you got to multiply by two
Bingo Steven! thank you sir
plz upload this solution file pdf
even Indian standards are quite typical and medieval
LMAO I love it
