The Ultimate Section Property Calculator

Increase productivity and design accuracy with S-CALC, a comprehensive section property calculator.

Ideal for sections having complex geometry and multiple materials, S-CALC calculates over 16 distinct section properties.

Generate cross-section properties using different calculation methods: database values, closed-form solutions, FEA methods and more.

Easily define models in S-CALC’s graphical editor or import geometry, material and section property data from AutoCAD® DXF and Revit® files.

Produce detailed engineering reports that include all section properties, geometry, material and graphics.

S-CALC’s Easy Shape Definition 3 Ways

  1. Easily define sections by selecting shapes from built-in steel databases (USA, Canada, Europe, Japan and more), all with support for Metric and Imperial units.
  2. Create custom sections by modifying any shape selected from an extensive shape library. Shapes include standard shapes, shapes with holes, hollow shapes, cold formed sections, reinforced concrete sections, bridge sections, rail sections, and user-defined polygons.
    Save time by using automated compound shapes that make it easy to define built-up shapes, including capped, plated, mirrored and crossed sections.
    Explode compound shapes into multiple child shapes to gain further control over dimensions, positions, and materials.
  3. Import shape definitions from a file using powerful, built-in data transfer links with AutoCAD® DXF and Revit® files.

section property calculates for regular polygon mutli-material concrete section

Generate over 16 section properties calculated about the centroid or any reference axis. Control the calculation method with options to use database values, closed-form solutions, proprietary polygon algorithms, or Finite Element Analysis (FEA) methods.

Quickly compare the results from the various methods in spreadsheet form to make engineering judgments.

Multi-Material and Composite Sections

Create multi-material sections and calculate properties based on the chosen reference material. Calculate Shear Area and Torsional Constant using Superposition.

Use default materials including steel, concrete, timber, aluminum, and iron, or change the materials to any custom values.

Custom materials can be exported into libraries and then imported into any S-CALC file.

S-CALC Integration with S-FRAME solutions and other 3rd party software

Easily transfer geometry, material and section property data between S-CALC and S-FRAME Analysis or S-TIMBER. Additionally import and export data with AutoCAD® DXF, or Revit®

S-CALC automatically converts disparate unit systems and performs point tolerance checks during import to ensure model connectivity.

Through automation and customization, data can be imported from, or exported to, any other structural analysis program. Any property can be exported or set from the imported data. Data can be used to create new sections and materials.

S-CALC Automation and Customization Capabilities

Automate any process or workflow and distribute it across your organization.

Save time automating repetitive or iterative processes like section sizing, scanning databases for appropriate sections, reporting, file read/write operations or FEA settings by creating automation tasks with the built-in S-CALC API and Integrated Development Environment. Optionally directly integrate our API into your .NET project.

S-CALC Reports

Easily generate detailed engineering reports suitable for presentations and organized into easy to read tables.

Reports contain

  • company-branded cover page, table of contents
  • cross-section graphics
  • all section geometry and section properties grouped by type and material properties

Optionally export report data to an Excel file format for easy data access and manipulation.
