RAM Reinforcement Design Status

Dear Bentley community. I’ve got a question concerning RAM.

I am designing a PT slab 200 mm thick and I’ve got a huge demand of reinforcement, even more than in the same slab designed as RC flat slab.

In the case of the RC flat slab the “Design Status” tab shows me a reinforcement that coincides with the “Rule Set Design – Strength Design – Reinforcement Plan”. It means, as expected, that ULS is driving in the design of the reinforcement.

In the case of the PT Slab the “Design Status” reinforcement shows me double than before, to cover the positive moments of a main span. I thought it may have been because of the SLS crack requirements but when I enter in the “Rule set Design” I don’t find any reinforcement similar to the one shown at “Design Status”.

What could be the reason for the big amount of reinforcement required and where can I find if it is due to cracking or to what? Shouldn’t it be in “Rule set Design”?? Where else?

 

Thanks a lot!
