Abstract:
Moment-curvature plots and moment-axial force interaction diagrams are essential tools for understanding the load-deformation behavior of structural elements. To make the use of these tools simpler, a user-friendly spreadsheet-based program was created that can generate moment-curvature plots and moment-axial force interaction diagrams for reinforced concrete sections. These plots can include the effects of confinement provided by transverse reinforcement on the stress-strain relationship of concrete. The spreadsheet contains a series of macros written in Visual Basic for Applications (VBA) and can be downloaded for free with the electronic version of this article.
