Thanks so much, but i´ve got a question. How would you calculate your cb in the case of a reinforcement in the top of a T-Beam. I dont know how to determine my s to calculate cb!
@@Hanna-cn2gj S is the spacing between the transverse reinforcement which is the stirrups ......so it is given in the question....read the question againg > it is a given value in the question .....and it is the spacing between stirrups and it's different about S Who he calculated which is the spacing between bars .
I noticed the same thing. I guess it could be 1.3 in that example if there was tension in the top face, but then the rebar was placed in the wrong face. Psi sub t should only be 1.3 when there is 12" of fresh concrete cast between the rebar in question and the extreme tension face that the said rebar is utilized for.
I looked at the third page of this link (people.tamu.edu/~mhaque/cosc421/CH5.PDF). Atr is the area of the transverse reinforcement which is the stirrup. Since you have a vertical piece of the stirrup on both sides of the beam, that's why it's (2)bars. It's not the horizontal rebars.
Show the spacing as it appears on the plants, Thats how students are being questioned these days, When u say spacing is 8 inches one may be confused that how’s it delivered on the test

Thanks a lot. Great explanation. Greetings from Venezuela.
Thank you so much ! Well done :)
Thanks... thanks so much.

Good !!
your explanation is amazing
Why the s is 8"?

What about for doubly reinforcement?
Sai t should be 1. Because there is no more than 12” concrete below rebar please let me know. Check the video at time 4:20z

How 2 bars crossing the failure point...
Dont understand this part...
