where I is the moment of inertia of the beam cross-section and c is the distance of the top of the beam from the neutral axis (see beam theory for more details). For a beam of cross-sectional area a and height h , the ideal cross-section would have half the area at a distance h / 2 above the cross-section and the other half at a ...
A441 – structural shapes and plates (Superseded by A572) A572 – structural shapes and plates. A618 – structural pipe and tubing. A992 – Possible applications are W or S I-Beams. A913 – Quenched and Self Tempered (QST) W shapes. A270 – structural shapes and plates.
Side view of a beam with two weld access holes cut into the web. Also the flanges have been beveled in preparation for welding. The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam.
In solid mechanics and structural engineering, section modulus is a geometric property of a given cross-section used in the design of beams or flexural members.Other geometric properties used in design include: area for tension and shear, radius of gyration for compression, and second moment of area and polar second moment of area for stiffness.
ASTM A992 is currently the most available steel type for structural wide-flange beams. The industry's technical institute describes the standard thus: "ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) is the preferred material specification for wide-flange shapes, having replaced ASTM A36 and A572 grade 50. There are a couple of noteworthy enhancements ...
Section Beams are made of steel and they have a specific lengths and shapes like Ɪ-beam, 'L', C-channel and I flanged beam. These types of section are usually used in steel structures and it is common to connect them with plates of steel.

Lateral-torsional buckling of an I-beam with vertical force in center: a) longitudinal view, b) cross section near support, c) cross section in center with lateral-torsional buckling. When a simply supported beam is loaded in bending, the top side is in compression, and the bottom side is in tension. If the beam is not supported in the lateral ...
