Section Property Calculator

Calculate Geometric and Material Properties of Standard, Arbitrary and Built Up Sections.

Use Sigma-X Section to calculate Area, Moments of Inertia, Neutral Axis, Elastic Modulus, Plastic Modulus, Section Centroid, Torsion Constant, Warping Constant, Shear Area, Shear Centre, Principal Properties and Equivalent Material Properties of any shaped cross section.  Sigma-X Section calculates the section properties using both the Boundary Element Method and the Finite Element Method.

Featuring the most powerful drawing and editing tools including zoom and pan, cut, copy, paste, delete, move, undo and redo, plus the ability to handle curves and voids and an active report writer.
 
Input data graphically, from tables, from our built-in library of standard sections, from AutoCAD dxf files or from digitised images (scanned photos or drawings).

Sigma-X Section has been proven in tests against ten other common calculation tools to be the only one which is 100% accurate 100% of the time.  Users are invited to take the 'Sigma-X Section Challenge' for themselves and compare the results from their  current calculation tools against calculations proven by theory and against Sigma-X Section.

Tests of 10 other section property calculators showed all of them to be incorrect and outside the acceptable limits of accuracy.  The tests found errors in both the basic load independent properties (area, inertias…) and load dependent properties (neutral axis, elastic and plastic moduli...).   It goes without saying that if any of these properties are wrong the design values for your section will be wrong.
