Really super bro thank you
It came for 15 marks in today's SEM exam (osmania university) !

Thank you so much 🤗🤗 . Itna badhiya content dene ke liye....

[@ayushgorana]

I see many lectures of civil engineering and all are good as your videos but one thing makes you different from them is that you answer and solve the all queries of students and while the other channels only answers 2 or 3 students queries

[@Civillearningonline]

Thanks alot for your appreciation.
I am trying my best. As much as i can.

Use Hindi instead of getting disturbed bcz of English rest u r lit God bless you 🙏🏻

Yes, dear it's very much different in starting a conversation and speaking in front of camer. By the way it's improving day by day. Thanks for your compliment.

Helical reinforcement ka dia 8mm kyu liya ? 🥲 ussi ke liye to pura lucture dekha vo hi samjh nhi aaya

[@sanjibsaha2315]

As u had increase the diameter of the column as 420mm..so in case of finding out the 'Asc' why u considered the Ag as the older one. .

[@nimapirhadi6135]

Thank you for this instructive video. May I know which standard is used for this design?

A little more explanation is required basically in calculating pitch of helix...

[@Civillearningonline]

Sure

[@Civillearningonline]

Calculation of pich is as per the code is 456 2000. Of clause 39.4.1. page 71 and clause 26.5.3.2(d) page 49.

Sir which method is used in this numerical?
My question is LSM or WSM?

[@Civillearningonline]

It's LSM.

[@reemsiddiqui0711]

@@Civillearningonline Have you uploaded Circular Column Design using WSM?? In any other Video

[@Civillearningonline]

Not yet. But I will.

Do formulas differ for ..round axially column and rectangular axially column?

[@Civillearningonline]

Yes

[@Ram-ty6gu]

Sir Area of helix m to longitudinal reinforcement nhi subtract krte h na

[@Civillearningonline]

Hello dear,
We need to subtract the area of longitudinal reinforcement from the area of helix.
It is because inorder to calculate the pitch of the helix we only need to have the area of helix reinforcement.
And one thing more,
We have considered the the diameter of helix after subtracting (2x40mm) cover from both sides. And u can notice in the inside the core dia. Longitudinal reinforcement is also included. And that's why we need to subtract the area of longitudinal reinforcement.so that the pich of core can be calculated and the codal provision is satisfied.
I hope i met your confusion.
Thanks for your comment.
Have a nice day.

[@mahammadyounus9295]

Use full forms bro If use ast,as, these differ

[@Civillearningonline]

Ok

[@hemanth._9]

Pitch condition 2 is not satisfied ❌
See pitch is greater than 1/6 th of core dia

[@nabinsah4957]

Yes bhai.
So we need to take intermediate value (i. E. Neither large nor smaller).
Hope you got it.
And thanks for your query.👍

[@Civillearningonline]

Sure

[@bhupeshchavan9597]

Sir how to check what is find in numerical?

[@Civillearningonline]

When you are asked to design then you need to calculate upto the lateral ties and some checks. Do as shown in this video. It's sufficient.
Remember: design means calculation of reinforcement.

Reinforced concrete design by B. C. Punmia 🤘

[@safdarkh786]

But 1.05 times means multiplied by 1.05, right?

[@Civillearningonline]

Hello dear,
First of all thanks for your comment.
You are right that 1.05 times means multiply by 1.05.
And when you come to read the clause 39.4 of is 456 it already mentioned that "strength of compression member with helical reinforcement = 1.05 Pu"
Where Pu is strength of similar material with lateral ties.
And initially we need to design longitudinal reinforcement before the helical reinforcement.
That's why we need to the the steps
(Given load x factor of safety)/1.05.
And i hope you got your answer. Do comment when you face any kind of difficulty. Stay connected with civil learning online.
Have a nice day.
