Midas Civil GSD moment curvature error

Question:

Midas Civil GSD returns a moment curvature that exceeds the concrete ultimate strain specified in the Mander concrete property windows. The attached screenshot shows that concrete strain of 0.0292 was reached at ultimate (point d), but the specified concrete ultimate strain is only 0.0186. This is a big different!
Answer:

Hi,

The concrete strain of 0.0292 is taken at the extreme fiber of the section and hence unconfined concrete. The ultimate strain of 0.0186 you specified corresponds to the confined concrete inside the cross-section.
