In this video Er. Sudeep Kumar Agrawal, Corporate Trainer of Civil Guruji, is Explaining About What is the Minimum and Maximum number of Reinforcement used in Column
What is the Minimum and Maximum number of Reinforcement used in Column
The percentage of steel should be minimum of 0.8% of Gross area of the section and maximum of 6% of Gross area, but the maximum area can be restricted to 4% of Gross area so as to avoid conjustion of reinforcement while concreting.
Minimum number of bars for rectangular column is 4 and Minimum bars for circular column is 6.
Minimum Diameter of the longitudinal reinforcement is 12mm.
Minimum diameter of lateral reinforcement is lesser of 6mm or one-fourth the diameter of Main reinforcement bars.
Minimum clear cover should be 40mm.
The minimum size of rcc column as per IS 456 : 2000 is 9″ x 9″, contain steel reinforcement of 4 bars of 12mm with stirrups of 8mm steel rings at a distance of 150mm centre to centre.
Minimum cross-sectional dimension for a Column: is 9”x 9” (225MM x 225MM). But to avoid slenderness problems, I recommend a rectangular column design of 9″x 12″ (225 MM x 300 MM) which is safer. What is the Minimum and Maximum number of Reinforcement used in Column
I always recommended to use use M20 grade concrete for construction, as it is the minimum recommended grade of concrete is IS 456:2000. Please don’t skimp on the quality of concrete. The minimum steel in a 9″ x 9″ column is 4 bars of 12 MM with stirrups of 8 MM steel rings at a distance of 150 MM centre to centre. In a 9″ x 12″ column, I add two more bars, to take the total to 6 bars of 12 MM diameter. This design can be safe for up to G+1 floors. But there are a lot of other factors involved.

Excellent knowledgebal video sir
Keep watching
Thankyou shudip bhai ❤️❤️❤️for important knowledge
Very Understand me
Good morning happy Holi day sir
make some videos. online courses on Estimate of Irrigation Engineering structures
🙏🙏🙏
Thank you sir fee Kitna hey from Nepal ❤️
thank you for infromaction sir minmum and maximum concreta in column how much sir pleasr make video
Beam upper bhi video bana dijiye
🔥🔥
Are 12 mm 4 bars and 10 mm 2 bars enough in a 9*15 column..?
The column to column distance is 15 feet.
How many storeys can be built with this much reinforcement..?
Sir I need COPs Professional course for lifetime validity.
Load k hisab se
Agr colm 1percent maang raha hai
Waha pr 0.8 percent provide kr diya toh?????
Sir 1 column different different bar Lagta hay uskliya kse pata lagata hey yaska ko koi video banya or
No of bar :-9.96 Aya to ten hota hey ki 12 ?
10
Sir acc to is code max rein 6% but calculate kiya aapne 4%
How 😮
