In this tutorial i have explained briefly how to calculate the quantity of steel for a two way slab
Before starting the procedure we must know how to identify a two way slab
If the ratio of longer span to the shorter of a slab is less than 2, the slab is considered as a two way slab slab
As i already told you that a one way slab is supported on beams on two opposite sides and the loads are carried along the shorter span
But in case of two way slab the supports are provided along all the dimensions since the loads are carried along both the directions.
I have illustrated this method with the help of an example
and at the end of this lecture i have shown you how to prepare the table for BBS of two way slab.
It should be noted that the spans are to be considered by excluding the width of beam from all the sides.

@5:20 I forgot to deduct the 45degree bends (2x1d= 2x1x8=16) after applying the formula for cutting length of distribution bar.... The cutting length will be 4.66m....total length will be 98m & total weight 38.7Kg or 38Kg..... Please do the calculations accordingly.... Sorry for the error!

[@gajjala4837]

You forget one more thing that is D=slab thickness - 2×clear cover -diameter That's D=150-50-8= 92 But you mentioned there D=150-50-8=84 Sorry for telling this little thing

[@CivilTutor]

You are right....this has happened due to a typinging error.... Anyways thanks for correcting me! 😊

[@gajjala4837]

I don't knw one and two slab so I listen carefully.thats why I catch that point sir..

[@CivilTutor]

You are right....It's 92 (Typing error)

[@funny.gaming8388]

Extraordinary mind blowing 👍

[@CivilTutor]

Thank you! 😊

[@funny.gaming8388]

Ok

[@g.rameshpatnaik8699]

No words to say, Civil guruji🙏🏼🙏🏼🙏

[@sachin-ry7zr]

Overall great presentation

[@muthukumaranrkalaiselvim3154]

Excellent presentation. Please keep it up

[@CivilTutor]

Thank you! 😊

[@UdaykumarmM-lr8yj]

Sir in two way slab ,during cutting length of distribution bars the bends are not deducted in calculation please check once and verify the cutting length of distribution bar.

[@asgharbadshah5592]

Pls make a video on Mobilisation of Site ? What is mean by Mobilisation of Site ? What it includes ? Who will do Mobilisation on contractor? What are the merits of Mobilisation

[@imranhusain88]

Sir Top extra bar in L/4 (main bar at double spacing) in midle part is not mentioned.

[@karunakarpuli6356]

Sir excellent 👌 sir beautiful knowledge for civil engg sir please make video on BBS of staircase with example please as soon as early sir thank you so much sir

[@ogwangoluka1760]

In Ugandan we use maxpan in slab so I'm appealing to include in your calculations.

[@Mr61303103013]

❤❤❤❤

[@reshmaramesh7363]

Soooper 😍

[@oooooo-rt5km]

Nice fabulous ❤️❤️❤️

[@CivilTutor]

Thank you! 😊

[@guydedje6378]

Could you please illustrate how you get the cutting length of bars or indicate a simple pdf sketch? Thanks in advance .

[@dhrumilmistri5066]

Why 1× incline length...? What is 1?

[@learncivilengineering2927]

sir cutting length of main bar 2ld i cant understand that sir

[@bakiyarajkaliyaperumal8938]

mistake at distribution bar cutting length didn't minus the 45°bend ×2

[@ch.__Sr]

2 way all main bars sir,... Distribution bars not use...

[@amritpalsinghsehjra7959]

is it according to indian standards?

[@CivilTutor]

Yes

[@ataullahsiddiqui5142]

@4:00 Sir D= Slab thickness- 2*side cover - dia of bar D=150-50-8=92 ( Distribution bar) U wrote 84 please see it Sir

[@CivilTutor]

That might be a typing error.... I will rectify it. Thanks and Regards!

[@ataullahsiddiqui5142]

Okay Sir thanks

[@muthuprakasam2806]

Main bar is shorter bar but you put longer bar

[@CivilTutor]

In two way slabs main bars are provided along both the sides.

[@sscreation1629]

Where is extra top rods...
