Moment Curvature diagrams [MN-Kappa]

A multi-purpose moment curvature calculator.

Moment curvature diagrams are used in Civil Engineering for determining the stiffness and capacity of reinforced concrete. The current online version is capable of:

  • Various cross sections
  • Hollow cross sections
  • Custom material properties
  • Phased reinforcement application
  • CFRP reinforced concrete
  • Prestressed steel reinforcement
  • Steel fibre reinforced concrete
  • Bending moment - curvature interaction diagram
  • Axial force - bending moment interaction diagram
