A module that calculates the properties of
geometric sections (area, moment-of-inertia, center-of-gravity, etc).
- The program can calculate all properties that are required for the
design of cold-formed (light gauge) sections. All line sections (with
any arbitrary shape) defined in this program may be transferred to the
STRAP steel
postprocessor and can be designed as cold-formed sections.
- Also available as a stand-alone program - CROSEC.
Two general
types of sections may be defined:
Line
sections: Sections composed of a series of connected lines,
each with a specified thickness.
- Segments may be defined in any direction (including
diagonal).
- Several 'subsections' may be defined and joined to form a
section.
- Properties calculated include:
•Shear center, warping constant
•torsional moment-of-inertia
•torsional-flexural buckling constant
- The properties may be copied to STRAP geometry
- Tables of cold-formed sections may be added to the STRAP property tables by first
defining a general dimensionless shape
Solid
sections: Sections formed by a closed contour.
- Several separate contours may be defined to form a section;
additional contours may be specified as "holes".
- The properties may be copied to STRAP geometry.
- Properties calculated include: Torsional moment-of-inertia
(exact).
