Interaction Diagrams of Reinforced Concrete Columns

Plots failure envelope and interaction diagrams in both x and y directions of a reinforced concrete column

function Interaction_Diagrams(x,y,x_s,y_s,a_s,fc,fy)

Input:

x: x coordinates of section vertex (mm)

y: y coordinates of section vertex (mm)

a_s: area of steel bars (mm^2)

x_s: x coordinates of steel bars (mm)

y_s: y coordinates of steel bars (mm)

fc: compressive strength of concrete (MPa)

fy: yield stress of steel (MPa)

Output:

Column section, failure envelope, interaction diagrams in x and y directions are plotted in one figure

Example on how to use the function is also provided.
