- In this video, we will design different types of footing in CSI SAFE as per IS 456 and 1904 along with AutoCAD detailing of reinforcement. In addition, we will learn some practices followed in the site.

It is the best ever tutorial I have come across. Thank you for the sharing.
Glad it was helpful!
No words. I bow to your concept and explanation
Cheers
Thank you for this vedio. Its very helpful ❤️
Glad it was helpful!
Very Informative... Thanks...
Glad it was helpful!
Great work bro!! Can you make a series where you design a building in a complete way like from Foundation-columns-beams-slab along with idea on how to produce detailed drawings. Would be very much useful. Pls think about it. Thanks and all the best!!
Sure. will give a try soon
❤
Excellent Explanation. Sir!! Can you please make video for comparison of Design Results for RC building having Fixed case column VS model with real foundations (either mat or isolated or combined as suitable). I think that there are drastic difference in Beam, column , foundation forces .
Thanks
Will surely try.
if column in etabs had insertion point and if we export that points into safe......does size of load act on that point or does it act on the area of column....??
Please share excel, CAD and PDF files. BTW, awesome video. Keep uploading such content regularly
Will upload soon
Very nice video Bro 👍👍👍👍 it's very very useful for me..... And please upload pile foundation design in single pile and group pile, friction pile also design in CSI SAFE software 👍👍👍👍👍💝💝💝💝💝💝💝
Thanks. I will
Very helpful video.
Pls make one video on Pile foundation design also.
Okay sure
Please check for modulus of elasticity(E) for rebar.
When I design footing slab in strap footing , top layer rebar is required. Why ? Could I neglect?
Like normal isolated footings, can we taper eccentric footings (with strap beams) instead of providing rectangular slab?
Yes we can. But not in the face where strap beam is provided.
Hello. While designing does SAFE consider the critical case of shear, punching shear and moment or it does it give steel just from Moment POV?I have designed it manually and SAFE as well but it seems that steel is calculated from Moment POV only leaving out critical case of shear. Becasue pt and shear stress are inter related and Pt given needs to be increased if depth alone cannot satisfy the shear demand. Pls explain.
Yah. safe doesn’t consider shear force while calculating rebar
Can anyone tell me what is the use of modal datum story height above and story height below in modifying grid window
Thanks for the nice explanation. it was really helpful but I have a doubt,.. when do we consider ultimate strength load combination that you defined? coz although you defined both service and ultimate ,, but you are only using service load combination..
Ultimate load combination is used for structural designs like rebar calculation
Service load combo is used for bearing and deflection
Unit of calculated value of soil subgrade is KN/m2/m while in SAFE it is KN/m3
Sir I have doubt in raft footing bottom mesh( x and y direction) has main bar and distribution bar for top. Mesh also. But sir at bottom main steel ( x direction) is becoming a distribution steel at top. Y direction steel is main why ?
For mat/slab with double mesh reinforcement, bottom bar of bottom mesh is considered as main reinforcement which can be along either x or y axis depending upon moment and for top mesh , top bar is considered as main reinforcement due to reversal effect.
Sir please make an video regarding peb foundations.. i mean how to reactions and design it on safe
Will try.
while defining strips you choose the strip as per the size of the footing, but you calculate the spacing of the rebar taking 1000 mm width . For taking 1000 mm width i think we have to define the width of strip as 1000 mm , Can you guide me in this confusion?
In Slab property section, what is the difference between Slab and Footing ?
This video was very helpful for newbie like me , Thank you
You can clearly see the SI UNIT behind reinforcment values which is mm2/m so I took 1000 mm width.
Dai nice content and pls pls make videos on shear wall design and detailing from etabs
Yes how to detail shear wall from etabs
Yes I will
Sure.
Exelllent explantion is there any course we can enroll ,or purchasing full complete training videos
Will upload soon
How do you consider start width left and right ?
Try using different values for left and right, you will understand oyo.
How to check one-way shear in Safe?
You can't check it directly. You have to check it through shear reinforcement for slab. Follow this :
Go to Display > Show Reinforcement > Display type change to shear reinforcement.
This shear reinforcement is provided on basis of shear.
Sir, i have a doubt, why dont you take moments along both direction with vertical load as this comes always as support is fixed
Yes, we have to consider those moments for the design of footing. However, the values of these moments are less as compared to axial load, so it is avoided.
How to check for one way shear in SAFE?
It gives the shear reinforcement, check with concrete stength.
👍 sir do you have stepped footing notes.
No. Sorry I haven't designed it yet.
Sir could you please provide the cad file and Excel sheets
Please write your email id
I followed all of your instructions exactly but when I try to "run analysis", nothing happens. The window simply refreshes and that's it. it does not show any analysis result (deformed shape, soil pressure etc). HELP!!!!!!!!!!!!!
Are you still having that problem?
@@civilconst It was a bug. I uninstalled SAFE and reinstalled it. It's working completely fine now. Thanks for your great video!

Sir what are the restraints that should be enabled while designing concentric or eccentric foundations?
I only get reasonable results when I enable all the restraints and keep the Translations Z turned off
Sir can you share Excel sheet and drawing pdf
It's a paid resource. Please make payment first and will send you a link to download.
Dont we need to consider GF wall load when designing footing?
Yes we should.
@@civilconst But why in every video plinth beam is not modelled and wall load is not assigned...please make more clarify..how did u consider Gf load?
Ground floor slab i.e wall and plinth beam is directly resting on ground, so it doesn't contribute to footing load unless there is basement floor. @@krakinigneel372
@@civilconstBut doesnt plinth beam generally rest on wall below and then to the lower tie beam...i am aware about the slabs wall concept but not to the wall above plinth beam...Thank u for your response in advance...
Considering "wid"😂
