- Menus allow
the user to calculate cross-sectional properties for 19 different generic
shapes. 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.

- 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 T points upward.
This feature permits users to exactly match the orientation of the particular
problem that is being solved.
- The section
properties calculated include the centroidal location, moment of inertia,
section modulus, radius of gyration, plastic modulus, polar moment of inertia,
and the maximum and minimum moments of inertia. The shape is redrawn to scale
showing the centroidal axes.
- 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 "6061-T6
Aluminum" and the software will retrieve a value of 10,000,000 psi for the
elastic modulus.
- Section
properties can also be computed for composite cross-sections. Two different
materials can be selected and assigned to the desired portions of the cross-sections.
For composite shapes, results are given in terms of the transformed area method
for both possible transformations.

- Dimensions and
selected properties for the complete American Institute of Steel Construction
listing of standard steel shapes in both US Customary and Metric designations
is also included along with data on the various steel grades and the availability
of specific shapes for each grade.
- A tabular
format is created for each shape analysis to give details on how to compute,
for homogeneous shapes, (1) the centroids and moments of inertia, (2) the
plastic neutral axis and plastic modulus, and (3) the product of inertia.
For composite shapes, centroid and moment of inertia calculations are given
converting material A into material B and vice versa.
- The section
properties calculations interact with both the beam, flexure, and column routines.
