# Steel I Beam Cross-Sectional Area Calculator

I-Beams are one of the several standard structural shapes for steel. These types of beams are often used in trusses in buildings. I beam is generally manufactured from structural steels with hot and cold rolling or welding processes. Due to its shape, I beam has the high moment of inertia and stiffness which makes it resistant to bending moments. The following Steel I beam cross-sectional area calculator has been developed to calculate the cross sectional area of structural steel I beams.

#### Formula:

A = 2Bh + Hb Where, A = Cross Section Area B = Width h = Flange Thickness H = Flange-Flange Inner Face Height b = Web Thickness

### Example:

Calculate the Steel I Beam Cross-Sectional Area with the width of 50 mm, the flange thickness of 20 mm, flange-flange inner face height of 30 mm, and web thickness of 15 mm.

#### Solution:

Cross Section Area = (2 x 50 x 20) + (30 x 15)
= 2450 mm2.
