Powerful Structural Analysis
- SkyCiv Structural 3D is a full-featured online structural analysis software - including beams, plates and cables.
- Quick and easy modelling with datasheet and smart drawing features
- Multiple Solver types including: Linear, P-Delta (non-linear), Buckling Analysis, Cable Analysis, Frequency and Response Spectrum Analysis
- Import Multiple Load Combinations from US, UK, EU, CAN and AUS libraries
- Review reactions, bending, shear, stress, deflection, buckling and many more results
- Input 3D structures or import .dxf files and also solve for 3D results
- Smart Repair Model Functionality to help you identify and repair model-issues.

Plates, Cables and Buckling
SkyCiv is a powerful structural analysis software - supporting a wide range of elements.
- 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
- Full buckling analysis capabilities to ensure safety against buckling
- Buckling Analysis displays buckling shape of your model in both accurate (longer solver time) and simplified
- Frequency and response spectrum analysis

Integrated Design Standards
SkyCiv Structural 3D is fully integrated with local design standards including AISC, ACI, ASCE, NDS Eurocode, Australian Standards and CSA:
- Integrated Load Combinations from ASCE, AS 1170, EN 1990 and NBCC
- Steel Member Design for AISC 360, AS 4100, CSA S-16, BS-5950, EN3, IS-800, NZS3404, plus more...
- Reinforced Concrete Member Design as per ACI-318, AS 3600, EN2

- Connection Design for AISC 360
- Wood Design as per NDS, AS 1720
- Cold Formed Steel for AISI and AS4600

Integrated Section Builder
SkyCiv Structural 3D is fully integrated with SkyCiv Section Builder - our powerful online section analysis software:
- Save and Load sections from our library of Australia, European, American and UK standard sections
- Select from 15+ template shapes including I-beam, HSS, Channel etc...
- Cold Rolled shapes such as AISI libraries
- Your section isn't there? Simply add a custom section
- Perform operations such as: rotate, mirror and translate.
- Adding a section will also give the results of moment of inertia, centroids and further section properties.
- Preset materials means you can select your material from a drop down list for fast entry!

“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!”

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.

“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.”
