Raft Foundation Design in STAAD.Pro

[@subhajitmukhopadhyay4780]

BEST VIDEO I'VE EVER SEEN. WILL YOU PLEASE MAKE A VIDEO OF THE SAME WITH RAFT BEAM?

@@Tinytopic Thank you! Awaiting eagerly.

[@rajithpatelrg5855]

nice explanation sir, can you make a video on foundation support when we need to use Elastic mat and Plate mat

[@Tinytopic]

As far as I know, there is a video of it. Kindly go through the playlist.

Best video but how to see reinforcement?

[@Tinytopic]

You shall have to calculate it from the moments analysed

[@sureshkumar-ji5kn]

Can you please elobrate? How to check punching shear and one way shear in this model?

[@Tinytopic]

SQx & SQy will give punching shear value.

[@MohammedAhmed-bh1xe]

Superb explanation, dear sir

[@Tinytopic]

Thanks

[@MohammedAhmed-bh1xe]

I learnt raft design from you, Kindly tell me what should I input the subgrade value in support if my sbc is 450kn/m2 and allowable deflection is 50 mm, I'll tell you what I did.. Now if I divide 450 by .05 the value is 9000, since my plates were (.5mx.5m) I multiplied it then the value is 2250 is it correct? Or should I input direct 9000 kindly tell

[@Tinytopic]

SBC * 2.5(FOS)/50(SETTLEMENT)

[@johnneil1313]

​@@Tinytopic you forget to multiply it to 1000

[@ARVINDKUMAR-pr3it]

Best explanation

[@Tinytopic]

Thanks

[@ChintaSathwik]

how to check the settlement of 40mm in the raft plate model??

[@Tinytopic]

Check displacement in post processing

[@VikramSingh-dx4oe]

Hello my doubt is that suppose i have 100 kN/m SBC so what should be my subgrade modulus and how to compare with base pressure?

[@Tinytopic]

What shall be factor of safety and permissible settlement??

Can i take reinforcement from this design??

[@Tinytopic]

Yes

Sir rf section is mssing in formula section in my laptop

[@Tinytopic]

Tou shall have to buy one

how to generate load combination for rcc design

[@Tinytopic]

Load combination shall be same as your whole model.

[@civilmoments5706]

Helpful!

[@Tinytopic]

Thanks

[@sonuKumar-ck2vu]

How can i add rf section in formula

[@Tinytopic]

Can you elaborate??

[@venkatarao6562]

how generate load combinations

[@Tinytopic]

By Auto Load Combination

[@viralsheth9240]

In raft rction sign change is missing when we apply reaction of model to raft we change sign of all reaction

[@Tinytopic]

Watch again, in excel sheet it is done with add in

[@bharatsondhi9757]

Sqx and Sqy are one way shear and not punching shear

[@Tinytopic]

Okay

Its an add-in. You can read about it in description.

Can you elaborate??

[@azmat_waseem]

For Sub-Grade Modulus, Under Create Support - Foundation - You have selected "None" instead of "Compression Only" Why? I think we should select "Compression Only" when we define/assign Sub-Grade Modulus....

[@Tinytopic]

Yes, you can use that too.

[@johnneil1313]

That is depends on your assumption on how your footing should behave. Compression only works if you want your footing to behave in compression but if you have uplift and lateral load by doing that you need to have large size of foundation in order to satisfy that assumption of yours. That is why staad put the "none" selection
