Hello
Thank you very much for this tutorial
But please, what does those moments and forces mean? I mean F11, F22, F12, M11, M22 and M12.
Which one of them is the lateral moment, torsional moment, vertical moment, radial shear, lateral shear and thrust?
Thank you very much as I anticipate your prompt response.

This is good but sir how will you tell the reinforcement details? Detailing part? Can you do it on etabs?

[afamarinze]

Hello, what if there is to be a spiral beam to support the stairs as it declines? Ho will that be modeled? Plus if a straight column is to support the spiral too? State the procedure for this two pls

[beenay]

is it possible to design elleptical spiral staircase

[geostructureacademy]

It’s modelled as shear wall. Not a floor slab object...

[abdallayousif]

engineer i modeling it in sap just i need to know how i can know what is torsion ? i get m11 and m22 just how i can get torsion

[nandhuprasad]

Sir.. How do we find the reinforcement required for design of spiral slab..please provide a valid solution like formula or a software which can solve this problem...

[sivajiatturi]

sir please tell the what are slab properties taken and sir you given dead load 25lb/ft2 why...?
in spiral case you did not mention any circumferential beams will i need to provide are not..?

AOA....
DEAR RESPECTED SIR CAN YOU PLEASE GUIDE ME/US ABOUT GETTING MOMENT VALUES FORM ETAB MODEL AND THEN EXEL SHEET TO DESIGN THIS TYPE OF SPIRAL STAIRS...THANKS IN ADVANCE ..
SECOND ADVISE CAN BE ..PLEASE MAKE A FULL SEPARATE VIDEO ON THIS THANKS
