# Steel I Beam Moment of Inertia Calculator

I-Beams are also known as H-Beams, W-Beams (for 'wide flange'), Universal Beams (UB), Rolled Steel Joists (RSJ) or Double-T. I-Beams have an I, or if you rotate it, an H-shaped cross-section can be seen. The horizontal elements of the 'I' are called 'flanges', while the vertical elements are the 'web'. The following Steel I beam moment of inertia calculator has been developed to calculate the Steel I beam area moment of inertia and polar moment of inertia.

## Steel I Beam Polar Moment of Inertia Calculator

I-Beams are also known as H-Beams, W-Beams (for 'wide flange'), Universal Beams (UB), Rolled Steel Joists (RSJ) or Double-T. I-Beams have an I, or if you rotate it, an H-shaped cross-section can be seen. The horizontal elements of the 'I' are called 'flanges', while the vertical elements are the 'web'. The following Steel I beam moment of inertia calculator has been developed to calculate the Steel I beam area moment of inertia and polar moment of inertia.

Code to add this calci to your website

#### Formula:

Ixx = H^{3}b / 12 + 2[h^{3}B/12 + hB(H + h)^{2} / 4]
Iyy = b^{3}H / 12 + 2(B^{3}h / 12)
j = Ixx + Iyy
**Where,**
Ixx = Area Moment of Inertia(X-Axis)
Iyy = Area Moment of Intertia(Y-Axis)
j = Polar Moment of Inertia
H = Flange-flange Inner Face Height
b = Web Thickness
h = Flange Thickness
B = Width
Just input the width, flange thickness, height and web thickness of the Steel I Beam Moment of Inertia Calculator to calculate the **Area moment of inertia & polar moment of inertia** of the structural steel I beam.
