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 W310x74 steel profile weighs 74.0 kg/m (49.73 lb/ft), has a depth of 310 mm (12.20 in), flange width 205 mm (8.07 in). Cross-sectional area: 9,290.6 mm². Moment of inertia Ix = 16,098.75 cm⁴, Iy = 2,342.36 cm⁴.
