Hello everyone!
I have a question:
Why do we need a main bar / alternate bar and also GradeInfo in Rebar Codes in ProConcrete? Where are they used?

Ruan Mistiakov
Hello Ruan,
Thanks for posting your query over the Bentley Communities Forum.
In response to your query, the parameters are set differently for 'Main bar' and this will be taken into consideration when you are modelling the longitudinal, vertical and main reinforcement in you 3D model for concrete objects. These values are taken from the WorkSpace Standards.
However, if you are modelling ties in column reinforcement or stirrups in beam reinforcement, then these rebars will be treated as 'Alternate Bars' and the values of bend radius and leg lengths will be taken from the ones set here in the ProConcrete Code being used (see picture below) -
Also, when you are using the custom reinforcement tools, like 'Single Rebar Distribution' or any other, you have the option of treating the modelled rebars as stirrups, which will then apply the values of 'Alternate Bars' for these rebars that will be created.
If you leave the 'Stirrups' option unchecked, then those bars will be treated and 'Main Bars'
We recommend you to also refer the below Wikis -

Hello Alistair,
Thanks a lot for the answer - a very accessible explanation.What can you say about the grade info?
Hi Ruan,
A particular rebar size is available in more than one grades. Thus, the Grade Info would include the 'Bar Grade' and material information of the respective rebar.
