Design of Doubly Reinforced Beam Flexure - I

[@nirmalyadavnk2097]

At 24:44
The Compressive force due to concrete is wrong.
It's
(.36fck)(X)(b)
What's the sir tell us
It's limiting moment capacity

[@abranbsingh1024]

indeed.

At 48:01 , the Additional Moment should be, Force*distance from neutral axis = fsc*Asc*(x-d') , isnt it ?

[@rishab59]

nope its force x lever arm

Lecture summary
What is a doubly rf beam?
Why use drb?
Basic assumptions
Stress levels in terms of yield
Steps taken in trms of analysis

[@Rayquesto]

doubly reinforced "generally" increases Mn strength.

[@Vikas-kf5ys]

how you calculate strain at duration 34:41 strain vs stress on design stress-strain curve please tell.

[@chaitanyakumar3772]

(0.8*0.87fy)/Es + 0.002 -- strain in steel formula , we ignore 0.002 here,
(0.8*0.87*415)/200000 = 0.00144

[@suryasutradhar717]

@@chaitanyakumar3772 why ignored?

[@arpankanungo8688]

rather than complaining watch the lecture at 2X, much better

[@santoshsaini6597]

when he writes , 2 times speed is also very slow

[@UjjwalKumar-]

No , x 1.25 is Good

[@rohny5587]

Jada fast mat bno exam m sabki speed 0.25 X hi hogi .. overconfidence 😂

[@ahsansharif1713]

Dear Sir, i'm a little confused on the derivation of the equation of (2n-1)As' transformed section. Please help.

[@susantaswain7462]

thank you so much sir...for these useful lectures...

[@swastiksubedi]

How to calculate 0.00144 for fe415 (.8*0.87fy) wahts the formula

[@_sharmaji_ka_ladka]

Stress strain curve page no. 70 IS 456. Add 0.87fy/Es to the indicated strain values

[@gali2734]

God bless you sir

[@MitaliPatel]

Sir I want to solve problems using cfrp composite using near surface mounting techniques than how to solve the problems.please give me solutions it's very urgent please

[@arwazkhan1176]

sir how to calculate strain in chart...

[@chaitanyakumar3772]

(0.8*0.87fy)/Es + 0.002 -- strain in steel formula , we ignore 0.002 here,
(0.8*0.87*415)/200000 = 0.00144

[@prakashyekkaldevi7177]

thanks a lot sir for such a useful video

[@CRICKETIPL-nk5kd]

better hai but hindi m hota to aur jyada samajh m aata ! mai nptelhrd se request karana chahata hu ki wo hindi m upload kare

[@TravelWithAjaj]

lots of thanks sir

[@abinashpanda4829]

Sir, tell me something about Mulim....

I think should take english learn first

+santhosh reddy Before you comment on his English you please improve your writing skill.

[@fretzT_T]

He's actually saying that 'he' should learn English before attending these lectures, so he can understand them better.
