Universal beam sizes, dimensions and section properties calculator per BS 4-1:2005 "Structural steel sections. Specification for hot-rolled sections" and Steel Designers' Manual. BS 4-1 standard specifies the dimensions and mass of the hot-rolled structural steel sections: universal beams; universal columns; universal bearing piles; joists; structural tees cut from universal beams; structural tees cut from universal columns; and parallel flange channels. Dimensional, mass, length and straightness tolerances for universal beams are given in BS EN 10034.
Moment of inertia, elastic section modulus, radius of gyration, torsional index, warping constant, torsional constant and plastic section modulus values are given for universal beam size.
Note: Use dot "." as decimal separator.
Second Moment of Area: The capacity of a cross-section to resist bending.
Radius of Gyration (Area): The distance from an axis at which the area of a body may be assumed to be concentrated and the second moment area of this configuration equal to the second moment area of the actual body about the same axis.
Section Modulus: The moment of inertia of the area of the cross section of a structural member divided by the distance from the center of gravity to the farthest point of the section; a measure of the flexural strength of the beam.
