Shear and Torsion Reinforcement Design by Etabs

On request of youtube fans I have prepared this important tutorial on Shear and Torsion Reinforcement Design by Etabs.
It includes determination of shear Reinf. spacing & no. of torsional Rebar using design value from Etabs.

1.Sir, Why don't you check shear rebar for tension by plus with shear rienforcement (Av/s+At)s ?
2.Why I display shear plus torsion rienforcement isn't equal shear rebar for tension+shear riecforcement ?
3.Why you don't use nos.rebar from show detailing of beam?

My stair beams are faling due to "shear stress due to shear force and torsion together exceeds maximum allowed". Alreasy provide beam of 12 x 24 inch which seems to me too much for a 6 storied building. Sbould i release torsion?

Sir, Please share the link of the excel sheet with us as it seems that without the excel sheet we can not make it.... Thanks, regards

Hi Sir, And thanks for the video!
When i run the model, i am facing a problem with torsion at beam to slab edge. The torsion forces are high in the beam and in many cases FAILED to design and this is perhaps wrong.
After reading here and there about the issue online, it seems that other designers are facing the same issue and the solution found was to set the torsion to 0.01 in the beam property / stiffness modifiers ...
My question, is that OK?
Is there is another way of setting up the model without having this torsion error?
The location of the beams which are failing due to torsion are located on the building perimeter. I think that its more a geometry issue, maybe etabs are reading the forces from the slab to the beam acting to the inner edge of the beam and for that causing torsion..
Your support will be appreciated.

The shear reinforcement given by Etab for any beam is three values in that middle value is higher one from middle Zone B portion of it is the shear area of center point of beam? Also end values of the shear reinforcement are also higher in the range of "2d" as per Indian code or something else? Kindly explain this.

how can we get that XL sheet

Thank you

sir assalamulikom, in your etabs tutorial all column was in the center but how to design eccentric column?cna u tell me pls

[djongmeilleur]

Please can you do a video how to design the shaft lift.

[kalehobhob]

assalam alycom please sir kindly provide a video explaining how to design a concrete core for torsion

[kkb]

Shall we find this torsional reinforcement after releasing torsion I.e. after changing torsion modifier?
