Hi guys. Just a question.
I am modelling my columns and beams in section designer. I noticed that in SAP2000, Mander's ( confined) can be modified inside Section designer including the ties spacing which can affect the stress-strain curve of the concrete.
But in ETABS, as I model the columns in section designer, I noticed that I cannot modify ttie spacing. Also, I dont know if nonlinear properties of concrete are already incorporated in the model automatically.
thoughts?
