Structural calculation sheet for the nominal interaction diagram of a 50×50 cm square reinforced concrete column. The design specifies 12 longitudinal reinforcement bars of 1-inch diameter arranged in a symmetric grid. The file provides the P-M interaction curve (Pn vs Mn) including the balanced point and maximum compression limits.
Calculations follow the E.060 standard hypotheses, detailing the section geometry, strain distribution, Whitney stress block, and nominal compression capacity (Po, Pn). It shows the resulting interaction envelope for the principal axes of the section. diagramas de interacción nominal columna.
