Web8 dec. 2024 · Column Interaction Diagram/Curve Explained. Vertical members that are part of a building frame are subjected to combined axial loads and bending moments. These forces develop due to external loads, such as dead, live, and wind loads. Simply put, an interaction diagram (or curve) displays the combinations of the acceptable moment … WebThis tool allows you to calculate the cracking moment for a rectangular concrete section. It also calculates the neutral axis and stresses in the concrete and the steel in both cases, before and after cracking.
