Dimensional Properties
- Mass per unit length (kg/m)
- Width of Section A (mm)
- Thickness of section t (mm): The vertical part connecting two flanges
- Root Radius r1(mm): The fillet radius at the connection of web & flange
- Toe Radius r2(mm): The fillet radius at the end of the section
- Distance of center of gravity (C = Cx = Cy)
Mechanical Properties
- Second Moment of Area(mm4): A geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. We mainly consider about the following two axes only
- About x-x axis
- About y-y axis
- About u-u axis
- About v-v axis
- Radius of Gyration(m): The radial distance to a point which would have a moment of inertia the same as the body`s actual distribution of mass. The moment of inertia is considered about the x-x and y-y axis or v-v axis and u-u axis.
- Elastic section modulus(cm3): It is defined as the ratio of the second moment of area to the distance of the neutral axis to any given fibre. Here, the neutral axis is x-x or y-y.
- Torsional Constant: A geometrical property of a bar`s cross-section which is used to determine the relationship between angle of twist and applied torque. The details of its calculation are given in SCI publication P057 Design of members subject to combined bending and torsion
- Slenderness Coefficient: There is only one value for slenderness coefficient for equal angles which is based on either of the axis of section.
