Explanation

The moment of inertia of an angle section can be calculated using the equations shown to the right. B represents the section's width, H is its height, and t is the thickness of the steel.
Iyy0 and Ixx0 are the moments of inertia of the section about its base. The parallel axis theorem is applied to this value to determine the moments of inertia about the section centroid, Iyy and Ixx.

Ixx0=t(H3+Bt2−t3)3 Iyy0=t(B3+Ht2−t3)3 Ixx=Ixx0−Ayc2 Iyy=Iyy0−Ayc2I_{xx_{0}} = \frac{t(H^3+Bt^2-t^3)}{3} \\\ \\ I_{yy_{0}} = \frac{t(B^3+Ht^2-t^3)}{3} \\\ \\I_{xx} = I_{xx_{0}} - Ay_{c}^2 \\\ \\ I_{yy} = I_{yy_{0}} - Ay_{c}^2
