Design of reinforced concrete helical staircase using Euroode2 3

[tadjou laura]

Hi

My name is Boris. A new member of the forum.

Usually in Eurocode for design of reinforced concrete theoritically we read from CHART(TABLES 177 of REYNOLDS AND STEEDMAN, 2005]. From this chart we can easily do the structural analysis or calculate the forces (vertical shear, radial horizontal shear, Axial forces, Torsion, horizontal moment, vertical moment at different angles.

Where can i find this chart please?? I Searched it on google but can't find it. please is there any document where i can get this chart from??

I don't use robot so I can't help with the raft but here's something to consider.

Determine the shear stress of a typical column, say 180psi (1.34n/mm2)
Determine the shear capacity (punching) of raft. If it's greater than 180psi (1.34n/mm2) then you know that thickness is going to work. I normally use a 0.85 ratio as this just a rough check. This is based on the assumption that shear will control over moment.

Okk, thank Sir. Make effort to finish these calculations latest Thursday.

Please Sir, hope that i may be dedicated a bit of your time, this week and next week (the final week) for final questions and corrections Sir.
