Construct a column on Tekla from Monolith mesh

Hi all,
I have optimised a structure of column on Monolith, and now I am trying to connect the Monolith mesh to Tekla component on grasshopper to do the structural analysis. How can I convert from Monolith mesh to Tekla structure as a column? or is there a better way to do the structural analysis for reinforced concrete?

Thank you
