Secant Stiffness

Interaction diagram to determine the biaxial bending resistance of a reinforced concrete cross-section. It shows the My-Mz diagram for a given axial force N.

The image shows a moment-moment interaction diagram that analyzes the biaxial bending resistance of reinforced concrete cross-sections. A horizontal My-Mz diagram is used to visualize the interaction between moments and a given axial force N. The option of connecting to a three-dimensional interaction diagram allows the visualization of the section plane in space.
