Cross-Section Properties

The stand-alone program RSECTION determines the section properties for any thin-walled and massive cross-sections and performs a stress analysis.

RSECTION can be connected to the FEA software RFEM and the structural frame analysis software RSTAB. Sections from RSECTION are also available in the RFEM and RSTAB library. Conversely, internal forces from RFEM and RSTAB can be imported into RSECTION.

You can enter the data graphically, in tables, by importing a DXF file, or via script.

Input

RSECTION contains an extensive library of rolled sections, as well as parametric thin-walled and massive cross-sections. They can be composed or complemented by new elements.

Graphical tools and functions allow for modeling complex section shapes in the usual way common for CAD programs. The graphical input supports, among other things, the setting of arcs, circles, ellipses, parabolas, and NURBS. As an alternative, it is possible to import a DXF file that is used as the basis for further modeling. It is possible to model a cross-section consisting of different materials.

Furthermore, a parameterized input allows you to enter the cross-section dimensions and internal forces in such a way that they depend on certain variables.

All inputs can also be done by means of scripts.

Calculation

RSECTION calculates all relevant cross‑section properties including the plastic limit internal forces. For sections consisting of different materials, RSECTION determines the ideal cross-section properties.

The stresses from axial force, biaxial bending moments and shear forces, primary and secondary torsional moment, as well as warping bimoment can be calculated for any cross-section shape. You can determine the equivalent stresses according to the stress hypothesis by von Mises, Tresca, and Rankine.

Results

All results can be evaluated and visualized in an appealing numerical and graphical form. Selection functions facilitate the targeted evaluation.

The printout report corresponds to the high standards of the FEA software RFEM and the frame analysis software RSTAB. Modifications are updated automatically.
