Cloud Based Section Property Analysis Software

SkyCiv Section Builder is a comprehensive section property analysis software that allows you to analyse geometric, bending, shear, and torsion properties. Build your sections out of multiple shapes from templates, or define your own via points, line paths, or a DXF import from CAD! Model and analyse your sections faster than ever!

SkyCiv Engineering Software is all online. This allows users to access their programs and files from a web browser. Work from anywhere, anytime! No need to install or update the program. This is a cost effective solution with no further costs such as maintenance or updates.

  • Choose from:
    • Rectangular/Square
    • Hollow Rectangular/Square
    • Circular
    • Hollow Circular
    • I-beam
    • T-beam
    • L-beam
    • Channel

Custom Shapes

Need to model a shape not available in our templates? Specify your own custom shapes:
  • Points Shape: Define points and create your own polygons. Specify fillets at any point.
  • Line Shape: Define a line path and create a polygon with a thickness and radius.
  • DXF Import: Prefer to sketch in CAD first? Simply save to a DXF file and import into SkyCiv's Section Builder for analysis.

Fully Integrated

The great thing with SkyCiv, is under one account you are given full access to all our Structural Analysis Software. The Section Builder is then also:
  • Fully Integrated with SkyCiv Structural 3D
  • Fully Integrated with SkyCiv Beam
  • All included in one account - full access to all the above software under one account!

Built-Up Sections

Model your built-up section by adding multiple shapes:
  • Add shapes from one of our many templates.
  • Operations including rotation, translation, and mirroring can be used to specify relative positioning.
  • Calculate geometric, bending, shear, and torsion properties.
  • Utilises meshing and FEA to solve torsion constant and warping constant. More accurate than approximate methods which only work for some geometries.

Hand Calculations

Get full, step by step, hand calculations for your section properties! Hand calculations available for:
  • Area
  • Centroid
  • Moment of Inertia (About z, y, zy (when relevant), and principal axes
  • Angle of Rotation
Hand calculation feature current available for Rectangular, Hollow Rectangular, Circular, Hollow Circuluar, I-Beam, T-Beam, Angle (L-Beam), Channel, and Triangular sections.

Composite Sections

Need to model sections made up of different materials? We have you covered:
  • Assign individual materials to individual shapes.
  • Preset materials means you can select your material from a drop down list for fast entry!
  • Calculate section properties via the Transformed Section Method.
  • Original section properties also presented in comparison.
  • Easily model laminar beams and other built-up sections made up of different materials.

Holes and Cutouts

Create holes and cutouts in your sections!
  • Simple checkbox to specify cutouts/holes.
  • Section properties calculated accordingly.
