A Square tied column $400mm$ on side is reinforced with eight $-25mm$ diameter bars equally spaced on all sides. Use clear cover of

$40mm,$ diameter of ties is $10mm,f^{\text{'}}c=21$MPa and $fy=415$MPa

a$)$ Compute for the nominal cocentric axial load that column could carry

b$)$ Compute for the nominal balanced axial load of the column

c$)$ Compute for the nominal balance moment

d$)$ Compute for the the nominal axial load and moment applied at eccentricity of $400mm$
