Retaining Walls - Provided Reinforcement & Workflow

Hi Everyone 😊

I’m writing to ask some help to the more experienced Robot users.

I’m designing a basement level (or a pool if you like), with 4 walls (retaining walls)
bearing onto a slab (raft foundation).

I’ve realised, after using Robot a bit, that the “Wall” command is not the right tool
(if used in these circumstances) as it doesn’t take in consideration any force out of the plane.

In the screenshot below you can see 5 “Floors” which are all “Shell”.
The raft foundation has got an “Elastic” support and is fixed to all the walls with a fixed support

(not sure if this is correct).

There are several loads applied on the structure (the screenshots shows just the soil pressure).

Provided reinforcement for one of the walls, the corners

don't have any reinforcement at all and just straight bars are provided.

Provided reinforcement for the fixed support (retaining walls)

 

What I would like to ask, is the below:

  1. Is this the right way to Design retaining walls in Robot?
  2. How comes that doesn’t matter what loads you apply, the provided reinforcement is ALWAYS shape “00”, which is a straight bar in the British Code?
    Is this a software limitation given by Robot which thinks that is a floor and not a wall?
    Am I doing something wrong?

Any advice or correction on my approach would be greatly appreciated.

Kind Regards,
Lorenzo

Hi @Lor_UK_IT 

 

Are you designing your wall based on BS-EN right?

 

There is no provided reinforcement module for BS-EN (or EN) in Robot. As far as I know, you can only get required reinforcement in BS-EN (EC2) for RC wall design.

 

May I ask how did you get 3D rebar detailing based on British code? 

 

Btw, you need to zip your file before uploading it to the forum.

 

Thanks

Hi @Lor_UK_IT 

 

How about design codes?

You shared only load combination codes not design codes. 

 

Thanks

@Lor_UK_IT 

This is not really the same kind of model.
Please share your first model or tell us your problem with this one.
