SkyCiv Section Builder

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 completely cloud based. This allows users to access their programs and files from a web browser, 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.

General Section Designer Plugin

The software also comes equipped with general concrete section designer, which allows you to model, analyze and design concrete sections with reinforcement. The software is powerful to take any type of section built through the Section Builder. Simply add reinforcement and analyze to get your moment and axial capacities, stress/strain results and interactive M-N curves. Click here for more information on our SkyCiv GSD plugin.

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.

Concrete Section Designer

The SkyCiv General Section Designer plugin allows you to add reinforcement and loads to test your section's moment and axial capacities. Design your concrete sections easily, using SkyCiv General Section Designer:

  • Add template or custom shapes via Section Builder
  • Easy reinforcement input and editing capabilities
  • Load in common materials, or add your own custom materials
  • Apply multiple loads, testing more than one case in one go
  • Review moment and axial capacities, stress/strains, stress contours and utility ratios
  • Review real-time M-N interaction curves

Transformed 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.

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.

FEA Section Analysis (Coming Soon)

Perform analysis on custom and template cross sections to calculate bending, axial, torsional and shear stresses. This in-built feature allows users to apply forces to their sections to get quick stress results. Use as a secondary check, or for more detailed analysis of complex shapes with powerful cloud FEA.

Real-life verification from SkyCiv users

"Big advantage was that I didn't have to commit to an expensive licence. Very easy to use and thorough results. Would highly recommend and will continue to use the software in the future."

SkyCiv KipCon testimonial
“The ease of use and the presentation of the results are both awesome. I have had ongoing interaction with the support team and everyone is excellent!”
Mitch Frumkin, CEO of Kipcon
SkyCiv TexasAM University Software Testomonial

It is used for various civil and mechanical engineering courses and the students love it. We are happy with the continuous updates to SkyCiv as well, highly recommended.

SkyCiv StructSure testimonial

“It was easily the most intuitive package available to learn; it is particularly easy to build the 3D model and define nodes, members, supports, materials, sections, then apply loads & combinations.”
