The Ultimate Section Property Calculator

Increase productivity and design accuracy with S-CALC, a comprehensive section property calculator. Ideal for any standard or built-up geometry, S-CALC generates over 15 distinct properties for sections defined by one or multiple materials.

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

Easily transfer geometry, material and section property data between S-CALC and S-FRAME Analysis, AutoCAD® DXF and Revit® or generate detailed engineering reports.

Easy Shape Definition 3 Ways

Select from the latest steel databases from USA, Canada, Europe, Japan and more, all with support for Metric and Imperial units.

Define your own sections by customizing dimensions from an extensive shape library that includes 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.

Import your geometry with built-in data transfer links from AutoCAD® DXF and Revit® files.

Section Properties and Calculation Methods

Generate numerous section properties, including geometric, polar, plastic, principal, shear, torsion and warping properties. Geometric properties can be calculated about the centroid or any reference axis.

Control calculation method with options to use database values, closed-form solutions, proprietary polygon algorithms or Finite Element Analysis (FEA). Easily compare the results from the various methods in spreadsheet form to make engineering judgments.

FEA calculations support two methods; one appropriate for thin wall sections (which uses shell finite elements) and the other for general sections (which uses solid finite elements) for accurate calculation of shear center, shear area, torsional constant and warping constant.

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 Analysis and 3rd party software

Easily transfer geometry, material and section property data between S-CALC and S-FRAME Analysis, 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.

Automation and Customization Capabilities

Automate any process or work flow 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
  • section graphics
  • all section geometry and properties grouped by type and material properties

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