Column Interaction Diagram Excel !!hot!! -

c_bal = (ε_cu / (ε_cu + ε_y)) * d Where ε_y = fy / Es . In Excel: = ($B$4*$B$6)/($B$4 + ($B$7/$B$8))

To build a manual interaction curve, follow these general engineering steps: interaction curves & design of rcc column column interaction diagram excel

Our Excel sheet will rely on standard strain compatibility. We assume: c_bal = (ε_cu / (ε_cu + ε_y)) * d Where ε_y = fy / Es

C_s = As' * f_s' (Positive). Note: We must subtract the concrete area displaced by the steel. column interaction diagram excel
