AISC — Wide Flange (I-beam)
Wide flange beams (W shapes / I-beams) are the most common structural steel profile used in building construction. They are used for beams, columns, and girders in steel-framed buildings and bridges. Designed per AISC 360, Eurocode 3, and NBR 8800.
The W310x39 steel profile weighs 38.7 kg/m (26.01 lb/ft), has a depth of 310 mm (12.20 in), flange width 165 mm (6.50 in). Cross-sectional area: 4,886.5 mm². Moment of inertia Ix = 8,405.31 cm⁴, Iy = 726.7 cm⁴.
