Hi Friends
Bend Deduction in Reinforcement Steel
How to calculate bend deduction in bars as per is code,
Bend Deduction Formula

Great sir, this is priceless information

[@halalmeatshophk]

The elongated arc 0.047 compare to center line arc 0.0393 is almost 20% elongated. Will this 20% stretch in the steel affect the strength of the steel. Is there any specific limitation in IS code that sets any maximum limits to stretching of steel? if the bent is made with a larger radius, then the elongation can be reduced. is it a good idea to use a larger bent radius, for example above 3d instead of 2d?

[@tamalgiri5701]

4.10 : For CTD bar confirming IS 1786, k=4, which is generally used at site for RCC nowadays. If you take k=4 you will get bend deduction for 90°= 2# which is practiced at site. So for MS and HYSD bar value is different.

[@vikastripathi2696]

Upto a diameter of 16 mm, only deduction of 1D is used at site... 2D is a misconception. You can verify at site that if deduction of 2D is used, the hook length of the stirrups would be shorter than required.

[@ashutosharya1161]

@@vikastripathi2696 you don't get it , he is talking about the value of k for Mild Steel and CTD bars are different even in the same dia category , hence bend deduction value of both bars will also differ.

Sir after taking stirrup cutting length as 2(A+B)+24d , we need to deduct bends or not?

[@tanmoysahoo2381]

Please tell me the clause number in is code where its mentioned about bend angle and bend length. i really want to know.

[@manojpandey4725]

Wonderful video bro, just amazing

Sir, we have to take k value as 4 (up to 25mm dia bar) for steel confirming to IS 1786 So please confirm with that. Let me know if I am wrong.

[@guruprasadpatil9395]

sir agar mai stirrup cutting length find out kar raha hu or bend deuction 1d 2d 3d respective angle ke liye deduct kar raha hu to length calculation ke liye mai konsi length consider kar inside wali center wali ya outside wali

[@oldschool86]

Ek question hain. Aap ne 90 degree k liye calculation kiye hain. Agar 90 chorke koi aur degree k bend hain to kya sirf degree k valu change karke baki calculation eki rahega? Matlab har time kya 2R se arc length deducted hogi?

Sir , how to calculate haunch bar cutting length at any angle.Many of the VUP Underpass have haunch angle less than 45 degree. SIR PLEASE REPLY

[@diljin9454]

Sir as per is 2502 the value of k is 2 for mild steel, 3 for medium tensile and 4 for cold twisted bar 1786 as per above format if we substitute the value of k as 4 and derive values for bbs bend will it be correct.

[@nitinjain3612]

Very useful thanks sir

[@amritkshetri5528]

very neately explained sir. please explain meaning of hook allowance H and bend allowance B. how are they measured.?

[@sanjayborge2240]

Dear sir, I am still confused about on page no 10 of IS 2502:1963 table V , A , Approx. Total Length of Bar (L) Measured Along Centre Line is A + E -1/2 R -d , sir I didn't understand this.regards.

[@sushilkumar-lm8nv]

A+E-1/2R-d here as per 3.2.1(Note-1) from this code value of R is k.d and value of k is 2 upto 25 mm dia bar. now, R=2d then A + E -1/2 R -d =A + E -1/2 (2d) -d finally for 1 bend deduction like table V / shape A length =A + E -2d

[@Ajit551kumar]

Sir 135⁰ &180⁰ ka kya calculation hoga please sir

[@rahulsaxena7123]

Root bending radius 20 kase ho sakta hai jab 10 mm bar hai

[@ankitkumarpandey667]

Excellent video sir. If there is no relationship between elongation and bend deduction , why these deductions are done? Basically there is a connection as -> ( elongation for outer bend - contraction for inner bend = deduction length ) . If deduction length is 0 then it may be said that there is no relationship between them , but there is some length left to deduct so there is connection !

[@kunaljha6837]

yes you are right in this elongation length is greater than contraction length so there is some length to deduct due to required elongated length so ultimately there is connection of elongation in bend deduction.

[@sanjaysinghkushwaha116]

Great job bro

Thanks kushwaha ji

[@omprakashchaudhary9385]

What will be the value of L for 135 degree or hook

[@kaustavghosal8465]

Sir, formula for cutting length of stirrup is 2(a+b) +24d?... It is as per center line?... Do we need to apply bend deduction in it?

[@tamalgiri5701]

2((a+d)+(b+d))+2x10d= given , 10d for hook. Bend deduction required when we calculate from outer dimension of ring. Generally we deduct cover and work with outer dimension of ring, so we deduct for bend.

Thank you sir ji......

[@SuperSaqibbashir]

As per is code we can calculate stirrup length as (A+B) +24d But when we use the concept of bend deduction as derived by you i.e 1.1d then two lengths do not match

[@vijaysoam1708]

i think center arch length to be consider for deduction

[@vijaysoam1708]

please confirm

[@deepchandrajoshi3665]

Why it is 1.1d ?? Is it in cm?

[@deepchandrajoshi3665]

I think 0.011 x 100 = 1.1cm

[@aakashgoyal3899]

Aapane 6 mm se lekar 25 mm tk 1.1 d kyo liya hai jo aapane calculation ki h usme different different coefficient hai

[@nitinbarfa7089]

How it's 1.1d It's come 0.011 Plz explain

But sr 2d hi Kyo minus ho rha Iska concept

[@rksingh1061]

Kab aayega sir

[@tarunce995]

Still not cleared why it is not followed @ site. Also there is NO elongation in a bend as centre line is same after i.e (elongation = compression). This deduction is due to the fact that while bending bar doesn't follow exact rectangular cornes & it takes curves/arcs which has less length than corners thus, this length is deducted from total length to exactly match the curved length practically seen.
