Perhaps rule number 11, we should spray galvanized over all outer reinforcement, including stirrups or at least etch and nutrialize metal to point of ph concrete pH will not react as much... Then we could add number 12, use a coating to protect exposed columns from water intrusion. Keep up your good work, I have posting on this for years now...
Nothing not graded and recommended in engineering should be sprayed as he could alter chemicals contained in concrete mix. Minimum rebars cover is based on building area too. To prevent water intrusion especially in salted air area, we would use a different type of cement like type 2 portland ciment with c3a < 8% or even a type 5 portland ciment with c3a < 5% which is better.
Thank you for the education, I have a plot size 60 × 25 ft, I. Want to make one big shop without middle columns and to construct four storey residential houses on top, kindly advise how will I design the columns and beams. Thank you.
I have planned to construct two separate rooms like 20*10 ( ground floor with 10*14 room size at first floor) & 22.5*10 (only ground floor) . My engineer suggested RCC is as follows. Pls tell it correct or not. Basement level of 22.5*10 is 2 feet less than 20*10 room 1. For 20*10 - 6 columns of 12*4 with 8mm stirr up of 7 inch c/c - four at each corner and remaining two at spacing of 8 feet at one end and 11 ft at other end. Plinth beam with 1.5 feet height and 9*9 (l*b). Ceiling height is 10 feet. Planned tie beam at below windows (2.5 feet) and lintel (7 feet) of 6 inch rcc 2. For 22.5*10 - 6 columns of 12*4 with 8mm stirr up of 7 inch c/c - four at each corner and remaining two at spacing of 10 feet at one end and 10 ft at other end. Plinth beam with 1 feet height and 9*9 (l*b). Ceiling height is 12 feet. Planned tie beam at below windows (4 feet) and lintel ( 8 feet) with 6 inch rcc And join the both room in ceiling and both room in 90 degree position to each other
M20 concrete ratio is 1:1.5:3 or 1:2:4 Which one is correct 2. Above mat how much depth we have to put concrete 3. Tell the reason for failure of column
sir,in your 5th rule you said about concrete cover. it means clear cover right. you are saying about effective cover, isnt it?. because effective cover is between top steel center to top edge distance. so concrete cover and effective cover same?
Sir your video is very informative. 1. Pl suggest the column width for a 25 ft X 44 ft plot (2 Storey Building) ? Is 12 “ X 12 “ enough with 8 Nos 12 mm bars ? 2.Also pl suggest maximum spacing between 2 columns in the above mentioned structure?
Hi sir plz reply my question,my house only G[G+0], span between 2 columns length 19 feet ,wedth 14 feet , size of colum 9/15 with 6 bars of 16mm rectangler column, all house walls 9 “wall. And first we make walls before slab it is safe or not ? Plz reply
MashALLAH yr really dua ha apke lia
I love your lecture, very helpful Sir.

Thank you for sharing.
🙂👍
I learned a lot from your video, good boy. Thank you sir
Good explanation...
I was laughing the whole time, the accent , the spellings,hahhahah any way good one.
Thanks so much teacher
Good civil engineering rules of column construction #
Peace to you my Honurable Engr. Sir, thank you sir.
thank you sir wonderful explanation keep it up
Useful info thanks
I have learned a lot about building from u
Thanks For Teaching SIr
Very useful RC column design rules.
Super sir
Thank you for the education, I have a plot size 60 × 25 ft, I. Want to make one big shop without middle columns and to construct four storey residential houses on top, kindly advise how will I design the columns and beams. Thank you.
Good explanation!
Thanks for share knowlegde.
Very informative video brother. Very well explained.
Nice presentation there sir. i learned a lot. Keep it up. More videos sir.
God bless you
Great teacher
Maasha Allah.

It is not readable pl due to light ink...
Masha Allah thanks
Thanks, I have been studying yr video n like it. Only a bit difficult in following yr accent.
🙏🏽❤amazing
Good message brother 👍
Thanks sir
Please upload to how prepare bar bending schedule ?~~

Thanks .
What should be the reinforcement ratio i;e steel qty.
Sir
What happensin colmn if concrete cover more than 25mm in rectangular column
I love your lecture, very helpful hope to get more information from you sir
Thanks a million sirji
Awesome though I didn't understand number six
Thank you sir

Nice bhai
Sir,
Can we construct 2 storey bulding with 4 nos. of 12mm rods in a column ?
nice one
How I know what is steel bar size is required for different colums for load bearing
Thank you very much
Ties spacing in IS code maximum 300 mm
Thanks again- from-Phils.
00000000000000000000000000000000
Is clear cover not same around tie of column sir......u said 25 mm from top and bottom and >15 mm from side:....shall we take same or different..
Plz discuss Acceptance criteria of concrete as per Britesh Standard
why extra steel/rod are putting below in the L/2 portion of beam? please
thank you very much,
Thanks Sir Ji
Allah Bless You Sir Ji
Is it possible to build a building in a single column?
M20 concrete ratio is 1:1.5:3 or 1:2:4
Which one is correct
2. Above mat how much depth we have to put concrete
3. Tell the reason for failure of column
Is there a height to cross section area ratio in columns?
How about determining the axial load for column sizing?
Calc the load transferring from slab to beams and from beams to column.
Square columns are always better in all cases
What about footing design if a soil is black cotton?
Minimum concrete cover for column I think should be 40mm not 25mm
what is minimum Beam size if 5x5 meter support column residential Building.
I didn't understand the first two rule how do we know when designing where the axial load would be to choose either square or rectangular column?
please make video on distance between two columns,grids and size of columns
sir,in your 5th rule you said about concrete cover. it means clear cover right. you are saying about effective cover, isnt it?. because effective cover is between top steel center to top edge distance. so concrete cover and effective cover same?
Hey sir ..is that safe if the depth of the beam less than that of the depth
How to do cost estimation for Foundations
Thank you, that's good
Please sir I would like to build a two storehouse only and coloum can this be done
Sir how would we know that load is on centre or eccentric?
Eccentric means the load is not passing through the centre and it passes at some distance from the centre
@@veerababuakula1344 Moron.
Sir, size of column plz....if G, G+1, or G+2 residential 4m span. Tnx.
THANKS SIR
How about 9meters span beam what should be the coulumn n beam
how we can know column is taking Axial or Eccentric load
excelant sir but more advertisments coming in short times . thank u.
For finding A zone and B zone in coloumn only two floor beams are considered,is not lintel tie beam required to considered?
All RCC columns should be designed for *
1 point
Shear
Torsion
No eccentricity
Minimum Eccentricity
Ans
Brother What happens if concrete cover less than 25mm...... ?
Sir if load coming on 3 then size of coloum?
The concrete cover for any RCC column should not be less than 50 mm.
What is pullers with 6 bars use like a shop covered area is 984 sq ft 1floor and 2 floor is 835+ 835 sq fts
In 7 and 8 you may mean vertical rather than longitudinal?
Sir your video is very informative.
1. Pl suggest the column width for a 25 ft X 44 ft plot (2 Storey Building) ? Is 12 “ X 12 “ enough with 8 Nos 12 mm bars ?
2.Also pl suggest maximum spacing between 2 columns in the above mentioned structure?
max spacing of columns should not be more than 5.5 metres
Thanks.
Hi sir plz reply my question,my house only G[G+0], span between 2 columns length 19 feet ,wedth 14 feet , size of colum 9/15 with 6 bars of 16mm rectangler column, all house walls 9 “wall. And first we make walls before slab it is safe or not ? Plz reply
