Online 3D structural analysis and design software

SkyCiv Structural 3D is our most powerful online structural analysis software, offering a full suite of modelling, FEA and design capabilities. This 3D frame analysis software allows you to model, analyse, and design various steel, timber, concrete and general structures. The 100% cloud-based engineering software allows users to access their programs and files from a web browser, from anywhere, anytime! No need to install or update. Unlike traditional software that is clunky and difficult to use, SkyCiv is by far the most intuitive and easy-to-use structural engineering software for civil and structural engineers.

Overview - powerful structural analysis

  • Full-featured online structural analysis software including beams, plates, rigid elements and cables.
  • Quick and easy modeling with tools such as datasheet, pen tool, operations and more.
  • Multiple solver types including linear, p-delta (non-linear), buckling analysis, cable analysis, plates, frequency and response spectrum analysis.
  • Import load combinations from US, UK, EU, CAN and AUS libraries.
  • Review reactions, bending, shear, stress, deflection, buckling and a full range of results.
  • Input 3D structures from Revit, Grasshopper, DXF, IFC and more.
  • Smart repair model functionality to help you identify and repair model-issues.
  • Ability to export steel and concrete models as automated Drawings.

Non-linear, plates, cables, and buckling analysis

  • Plate analysis - including deflection, shear/bending forces as well as a range of stress results. Includes a full meshing tool with multiple mesh types, cutouts, internal node detection that can be easily meshed and unmeshed.
  • Supports Mindlin quadrilateral shell elements suitable for thick/thin plate analysis.
  • Run cable analysis with accurate P-delta (non-linear) analysis; prestress cables and adjust cable lengths.
  • Thermal, prestressed and powerful auto-area load functionality.
  • Full buckling analysis capabilities to ensure safety against buckling.
  • Buckling analysis displays the buckling shape of your model in both accurate (longer solver time) and simplified.
  • Frequency and response spectrum analysis.
