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

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

is it possible to design elleptical spiral staircase
How Modeling of stair saw age ?
How to diagram moment?

Dear,
It’s modelled as wall object not a floor slab object....
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
does m12 mean torsion?
AOA....

+Sivaji atturi Slab properties as usual. 25 psf for Floor Finish. Beam is not mandatory.
what my doubt is i have consider it as shell or membrane slab
