Section Properties Module

  • Users can select from 19 different generic shapes. The shape is drawn to scale showing the centroidal axes, and where applicable, the principal axes.
  • General shapes include I-, T-, C-, L-, Z-, box, solid circle, pipe, and rectangular shapes.
  • Double shapes include double I-, T, C-, and L-shapes.
  • Either US or SI units can be utilized.
  • The elastic modulus of the shape can be entered directly or the user can select from a list of common materials. For example, the user could simply click on "Aluminum 2014-T6" and the software will retrieve a value of 73 GPa for the elastic modulus.
  • Buttons on the display form allow the user to rotate the shape to the desired orientation. For example, a T-shape can be rotated so that the stem of the tee points upward. This feature permits users to exactly match the orientation of the particular problem that is being solved.

  • A number of section properties are calculated pertaining to both the horizontal and vertical centroidal axes, including:
    • the centroidal location,
    • the moment of inertia (i.e., the second moment of area),
    • the section modulus,
    • the radius of gyration,
    • the plastic modulus,
    • the polar moment of inertia, and
    • the maximum and minimum moments of inertia.
  • The user can obtain additional details about the exact process used to calculate:
    • the centroid location,
    • the moment of inertia,
    • the product of inertia, and
    • the plastic modulus.

  • Section properties can also be computed for cross sections that consist of two different materials. Materials can be selected and assigned to the desired portions of the cross-sections.
  • For cross sections consisting of two materials, transformed area method results are presented for both possible transformations.
