Steel Structure Design Software
SkyCiv Structural 3D allows users to quickly and easily model their steel structures, and perform design checks from various design codes to complete the design process. Our design module also includes open step-by-step reporting, as well as an optimizer that helps users test all sections in a particular library, to find the most efficient shape.
Steel building design software developed by engineers, for engineers. Users of the SkyCiv suite drive the majority of changes and additions to the platform. SkyCiv software developers all come from a structural engineering background, with the majority being previously consulting structural engineers.

CFS and HR Integrated Design Modules
When your structural model is complete, import it and the analytical results directly into the Member Design module to run full design checks in accordance with a variety of design codes including:
Hot Rolled: AISC 360-16 LRFD/ASD, Eurocode 3 (EN 1993-1-1:2005), BS 5950-1:2000, CSA S16-14, IS 800-2007 LSM.
Cold Formed: AISI S200, ASNZ 4600
Full Featured Modeling Tools and FEA Analysis
Take advantage of the various modeling tools that make generating any type of structural steel model a breeze. With SkyCiv’s FEA solver, run your structural model using the following
Analysis methods: Beam, Cable, Plates, Linear Static, Buckling Analysis, P-Delta Analysis, Dynamic Frequency, and Response Spectrum.


Library of Sections + Custom Shapes
Whether its a database shape from one of the various country databases or a custom built shape using a variety of preset shapes. The Section Builder will use a full FEA analysis to obtain the section properties of single material or composite sections. Have a section drawn as a DXF? Directly import that shape into the SkyCiv Section Builder to analyze. All shapes used in the Section Builder are directly integratable with the SkyCiv analysis modules.
Design Steel Connections and Base Plates
Directly integrated with SkyCiv's structural analysis software S3D, SkyCiv Connection Design will enforce the design requirements of a variety of steel connections in accordance with the following design codes: AISC 360-10 LRFD/AS, EN 1993-1-8. SkyCiv's Steel Base Plate Design software also supports AISC, AS4100, Eurocode, Canadian and PH codes.
View the extensive hand calculations of the design to verify your inputs and abolish the blackbox. Each calculation references the pertaining code item, making it easy to back-check your results.


3rd-Party File Import Support
Get a headstart on your structural steel model using the various supported 3rd-party file types such as Revit (.RVT), .DWG, .DXF, .CSV, and Others in development!
With correctly formatted 3rd-party files, the majority of the modeling of your 3D steel structure can be completed, including material properties and section properties.
