Hi,

When using the reinforcement designer and calculating required reinforcement for SLS to CP65 this is done limiting the crack width to 0.3mm. If on a specific job I need to do the same calculations, but limit the crack width to 0.25mm, is there a way to do so in Robot?

Thanks in advance,

Jesper

1. Increase unit precision in Job Preferences

2. Set crack limit

Thanks Artur that's great, but how do you bring forward the CP65 Reinforcement Parameter Tab?

Thanks,

I'm afraid that I don't understand the question. Could you rephrase it please? Thank you.

If you open the attachement you made in your first reply, the bottom picture show a tab called "CP65 Reinforcement Parameters" where the crack width can be modified. Can you please let me know how I can access or open that window in Robot?

Thanks,

Jesper

Hi Jesper,

Hi,

Thanks for the previous replies, answers were perfect. I've another question in relation to the crack width calculations I'm hoping you can answer. I assume the crack width is calculated in the location as indicated on the attachment (between the bars at a distance acr) is that correct?

If I specify a 200mm cover, is there a way I can force Robot to calculate the crack width at a distance 40mm from the outermost bar, and not at the face?

Thanks,

Jesper

I'm afraid that I don't understand the question. Robot calculates cracks in these locations (s is based on calculated require reinforcement area and declared bar diameter).

Yes, that was my assumption as well.

In the dialog box shown above (4 in red brackets) called "CP65 Reinforcement Parameters" I can define the top/bottom cover under the tab called "Reinforcement".

If I set the cover to 200mm, is there a way to force Robot to calculate the crack width 40mm away from the reinforcement, instead of at the concrete face 200mm away?

Thanks,

Jesper

I'm sorry but there is no such possibility.
