Section Designer is intended for purposes of building any types of compound cross-sections out of steel rolled profiles and plates, and calculating their geometry properties necessary for structural analysis.
For the cross-section being designed the following properties are determined:
- cross-section area А;
- values of inertia momentum Iy and Iz around central axes parallel to the coordinate axes of the right Cartesian coordinate system Y and Z;
- inertia radii iy and iz around the same axes;
- inertia momentum for free torsion It;
- the centroid coordinates;
- values of the principal central inertia axes slope angle (the angle a between the axes U and Y);
- maximum Iu and minimum Iv inertia momentum;
- maximum iu and minimum iv inertia radii;
- maximum Wu+ and minimum Wu- section moduli along the axis U;
- maximum Wv+ and minimum Wv- section moduli along the axis V;
- core distance along the positive аu+ and negative аu- direction of the axis U;
- core distance along the positive Wv+ and negative Wv- direction of the axis V;
The values are calculated according to common conventions of the material science, the free torsion inertia momentum being defined approximately as a sum of free torsion inertia momentums of profiles included in the cross-section.
The following methods of assembling are implemented in the Section designer:
- an element can be connected by one of its key nodes to a key node of one of cross-section elements;
- an element can be connected by one of its key nodes to a cross-section point specified by its X and Z coordinates;
- an element can be attached by merging lines which connect two key points of the element being installed and the active element of the section.
When using the two first assembling methods, the element is included into a cross-section with a specified orientation. When joining along a line, the orientation of the element in the cross-section is defined by orientation of lines along which the elements are to be joined.
Overall sizes of the cross-section being assembled are permanently monitored.
A report (log file) can be generated after results of cross-section geometry properties calculations. A report is a file of the format RTF (Rich Text Format). After the report has been completed, an application associated with the RTF format (such as MS Word or WordPad) can be opened.
Results of calculating geometry properties can be exported to the Structure CAD analysis pack (version 7.27 and higher) as well as to the KRISTALL system for analyzing and inspecting elements of steel structures (version 2.1 and higher).
Cross-section components information
Information on section sizes can be obtained for rolled profiles used for building a particular cross-section.
The Section designer works in the operating environment of Windows Vista/7/8/10. User dialogue techniques and controls are in complete compliance with this environment.
Help (Reference Information)
The Section designer is provided with a detailed reference information (help system) which includes descriptions of the user interface and conventions for working with the application.
