Hi everyone,

I have been trying design RC wall of manhole, but I can't. Because, when I was design RC wall and layout steel.

And modelling I was create:

I have some problem as:

1. I can't calculated design RC wall of manhole according to British standard.

2. I can't create circle on the RC wall when I was calculated and layout reinforcement. 

I have seen video at link: https://www.youtube.com/watch?v=hNGov4oPYmk about created rectang but not apply for circle. 

3. I can't layout reinforcement for wall of manhole as figure 1 (file .cad)

4. I don't know how to create earth pressure is true.

So, somebody can help me fix all this problem. 

Thanks!

Hi @Anonymous

As you have lateral load applied to the panels you should design them using the RC Slab module of Robot

I recommend watching the recording of the RC Design - workflows slabs, walls and wall foundations design webinar.

You can apply the soil pressure following the steps shown on this video.

Hi @Anonymous

Just create a circular contour inside a panel. It will be automatically detected as an opening.
