Is there any other checks need to be made for a complete beam design? Thank you Sir for your constructive video, very well explained.

[@edmaestrejr.2450]

Thank you sir for your very well explained tutorial..can you make a video of (USD) Ultimate Strength Design of reinforced concrete by using S.I. units?

[@unitedwestand6554]

This is an amazing video I wish you could do a similar video for two-way slab as well as continuos beam

[@Sulimankhanacademy]

i will try soon

[@davidr2943]

(14:20) Wait, wouldn't the number of bars be rounded up? If you did the if you calc for #7 bar, you will see 3.276/.601 = 5.45. If you take traditional rounding methods, wouldn't you have too little of bar? I would make the number of bars 6 in that case. Or are safety factors assumed to be soaking up the logical need for rounding up? Would make work a bit simpler to simply round normally, but until I know more, I am going to round up all the time in that scenario. Maybe that mystery phi/diameter symbol does the safety factor? In the end it looks like the numbers worked out though after the check, so it should be okay as long as that check is done I would guess. Also, wouldn't "d" technically change with the height of the beam and the rebar cover? I see that this was good enough for starting with only paper on hand, but wouldn't you want to check the calcs with that new "d" value at least? I would think, in this case with the #8 bar and 1" rebar cover, that we would see d=19.875 ... Yes, I know, small difference, but I am an Excel lover, and these technicalities are something that change the approach to formulas, so I was curious if I was right there. Not really intending to correct, just looking for understanding. Another thing, regarding "b" I am a little foggy on that value as well. Is that the beam width, or more or less a center of bar width end to end? The manuals are expensive, but with all the ambiguity out there... might be a good idea to invest in the SERM (Structural Engineering Reference Manual) at this point xD Great video! Mostly designer by trade for 7 years here turning into more EIT roles, and this is a welcome refresher! Thanks a bunch!

[@Sulimankhanacademy]

Yes dear, everything you said is ok, you can do rounding of figures etcs, The video provides the method as needed in exams, otherwise I recommend softwares for design purposes,

[@davidr2943]

@@Sulimankhanacademy So in the exam, they really look for the ability to stay within the checks then? Seems like things like number of bar, in this case, is somewhat subjective as to the methodology. One of my biggest problems is being quick during a test. During work I do great because I can be exact by building an excel sheet. So is, in your opinion, the main thing the checks and methodology to the detail I describe can be subjective? If so, I would probably do it like you to save time along the way of getting to an answer while doing it long hand. Again, great video. Really was nice to have a break down. I bet a lot of people appreciate it! :)

[@finalpush-youtube]

Easy to understand. Nice explanation.

[@Sulimankhanacademy]

Thank you for compliment 💕

[@vincentmichaelg.sauler4514]

Second question, how to determine the diameter of the steel bar? How did you come up with the 0.5inches as half of the diameter of the bar? Thank you

[@Sulimankhanacademy]

Steel bars are available with different diameter..the diameter of steel bar is always written on its end.... I have assumed 1 inch dia so its half should be 0.5 inch

[@davidr2943]

#3 bar = 3/8" dia, #4 bar = 4/8" or 1/2" dia, #5 bar = 5/8"... etc. Basically, an 1/8" for every No (#) of bar is the diameter. That is probably the explanation you were looking for a year ago. :)

Why don't we check if the concrete can handle the pressure? So the tension that the steel needs to withstand is equal to the pressure at the top of the beam. How do we know that the beam will hold the pressure if we only calculated steel needed for the tension? Thanks!

Considering the Design Solution is Greater then the Mu. Can you not make a smaller Beam since 5177.875 is > Mu? 12 x 18 is 1.5 Ratio and 3888, so it still exceeds Mu?

Hi sir, I have a doubt regarding the design load, you refer to the unit of measurement k/ft and I hear say in the video "k per foot" . Is this k refering to kilonewtons? I checked the textbook you mentioned in the comment. I cannot find a clear answer. thx again.

[@Sulimankhanacademy]

Hello dear, k/ft means kips per foot in video. Kip is unit of load or force. One kip= 1000 pounds

My column size is 9 by 9 inch with out concreate and span is 16 feet please tell me the beam size no of bars in beam and their diamenter. I am thinking of 9 by 13 inch beam with out concreate and 4 bars of 16mm in bottom and 2 bars of 16 mm at upper aide of beam Please suggest me

[@davidcivil1651]

Dr Sb, nobody can answer you query. You said your column is 9 by 9 without concret. How a column can be without concret? 2) how can I know your beam length? 3) column can be designed after knowing the load of slab and beams. You will design a column to support your beam and slabs load not designing the beam for column.

hello. 1st thank you for joining sl khan. 2nd its easy to do this using calculator. here is the process . do each part separately like first do the portion of (1-(0.012)(60)/(1.7)(4) ) then do multiply with 0.9(0.012)(60) you will get answer. thank divide 3000 by same answer....
