L/20 is for steel beams such as I/H beams. For steel-reinforced concrete beams, it should be L/12 or L/15 as minimum. I am not a civil engineer, but that is what I've come up.
My question is for span of 7.6m in your earlier tutorial you said for span of 7.6m beam btw two columns the column size will be 400mm x 400mm and that the depth of beam is 7.6m/16. How come in this tutorial you said the depth of beam will be span/20 instead of span over 16. And if 7.6m span the column size is 400 x 400 I am thinking 8m will be 421mm x421mm taking reference from your previous lecture on 7.6m span
These ratios are the "span to depth ratios" are the minimum required so that the beam does not deflect based on it's own self-weight as such whatever depth you get from the basic ratios add say 150mm or 200mm to it to improve the moment resistance capacity of the section else depending on the load applied the beam might fail or require more require rebar ,in which case you will have to widen the width of the beam so that you arrange bars and still have adequate space around them for concrete .
Please tell where you are getting formula? Because i seen a formula... Depth of beam=L/10 ; Width of beam=L/12. For a 2 floor building but the L should not be greater than 6meters.
Can I have 8 meter long slab without beam? I mean - slab will be resting on columns which are apart from each other by 8 meters, and no beans between columns
Dir, you said the beam depth is 8000/20= 400mm,, my question is ,, Is this 400 mm beam including with slab thickness ?? or it is excluding slab thickness...
A good soil condition..I have to built a 4 story house...my architect designed 20feet beam ...our constructor planning to use 20mm 4 steel bars...also colum with 16mm 4 steel bars and 10mm 4 steel bars..is it safe..
Asalamualaikum brother.. It is Hafiz Adnan from Kashmir (Jammu and Kashmir) Hope u will be doing fine Firstly u used L/d formula for calculation of effective depth of beam Then u said I can bet that it will fail in very first trial... Then how can i myself decide
Is this formula used in the actual job setting? You said the final depth will still depend on the loading carried by the beam. Won't this require software like etabs or staad?
can be used , it is just example . all other reality factors are also count . Like steel quality , workmanship and site conditions etc. , So depth was taken little more .
@@maheshpratapsingh4049 yess, cuz actually in other codes or videos that ı watched or website, its mostly taken as SPAN/10-12 . I suggest u to use SPAN/10 if u wanna be safe OR SPAN/12 if u want adequate and SPAN/16 if u want it to be just okay

L/16 for simply supported RCC beams
thanks for the support and education
Super... you are my favourite teacher sir...
You deserve super like & admire
This is very basic but helpful video ...Good Explanation .
HELLO FRIENDS & ENGINEERS , IT IS A GOOD AND HELPFUL VIDEO .
Hi bro make a video on 30 foot span for commercial building
With column size and etc

I have also noticed the same case which you mentioned above.....
♥ U Sir,,,,, From Bangladesh,,
Please tell where you are getting formula? Because i seen a formula...
Depth of beam=L/10 ; Width of beam=L/12. For a 2 floor building but the L should not be greater than 6meters.
His value is bottom size or including ( Lenter ) RCC slap
sir can you please explain singley and doubley reinforced beam.. and also axial and biaxial column...
Can I have 8 meter long slab without beam?
I mean - slab will be resting on columns which are apart from each other by 8 meters, and no beans between columns
What about the steel size, number of rods, cover & stirrups Spacing & dia
Can u plz do this video once again with examples for each condition(cantilever beam & continues beam) for easier understanding?
Dir, you said the beam depth is 8000/20= 400mm,, my question is ,,
Is this 400 mm beam including with slab thickness ?? or it is excluding slab thickness...
When do you use D=L/16? You have used this in previous videos.
Thank you Sir so much 🙏🙏
as a general rule divide the span by 15
A good soil condition..I have to built a 4 story house...my architect designed 20feet beam ...our constructor planning to use 20mm 4 steel bars...also colum with 16mm 4 steel bars and 10mm 4 steel bars..is it safe..
Yes safe.
Asalamualaikum brother..
It is Hafiz Adnan from Kashmir (Jammu and Kashmir)
Hope u will be doing fine
Firstly u used L/d formula for calculation of effective depth of beam
Then u said I can bet that it will fail in very first trial...
Then how can i myself decide
Does it apply in drop beam also r only great beam
For 10 meter span ,what will be the depth and width...??? Is it possible to make beam for 10 meter length ( simply supported)....???
Sir , this 600 mm beam that you said,, is it including slab or excluding slab ??
Is this formula used in the actual job setting? You said the final depth will still depend on the loading carried by the beam. Won't this require software like etabs or staad?
Using what material?
अगर ग्राउंड फ्लोअर के हॉल की साईज 21 बाय 10 हे तो कॉलम और बीम की साइज क्या होनी चाहिये
Good morning Engr. Is it possible to construct a beam, 12 meters in length between two columns using I-beam for a two storey house?
On which basis you say that..? What types of code you are following..?? Also mention the code.. It is just only time wasting
That is bs code 8110
hello
sir
sir kiya aap autocad complete tutorials series bana shakte hooo please
thank you
Good👍
Please what do you mean by depth of beam.
Sir issme modification factor use
nahi hoga kya
hello sir If my span is 10 meters between two columns can I use trussed beams ?
Salam , can we mix between column for example en the center diffrent from the other.
If d distance between two columns 6mtr
What should d columns size is
Fixed beam?
How about the width of the beam? You only discussed depth
I was wondering if you could do a video on depth of continuous beam. Thanks.
I am confused cuz in other codes it says the depth of beam should be for simply supported SPAN/12 instead of SPAN/20
How about length of beam is 8m but existing column is flush in the wall size 20*60. Is the column ok?
Assalamualaikum sir can u teach us the surveying also please
I am looking for someone who can provide full report for Steel Structure - 700 sq Feet G + 3 Storey
ขอบคุณมากครับ
if is code is not safe for 8m span.. who the hell designed this is code
Why it is not 400 mm depth according to d formula......
can be used , it is just example . all other reality factors are also count . Like steel quality , workmanship and site conditions etc. , So depth was taken little more .
@@civilengineeringtolifeengi3333 little more?? It's almost double. Ratio should be taken span / 10 for simply supported beam...
@@maheshpratapsingh4049 yess, cuz actually in other codes or videos that ı watched or website, its mostly taken as SPAN/10-12 . I suggest u to use SPAN/10 if u wanna be safe OR SPAN/12 if u want adequate and SPAN/16 if u want it to be just okay
