WHY ENGINEERs SWITCH

Structural analysis software that runs the full workflow

Easy and powerful FEA analysis

Run linear, non-linear, buckling and dynamic analysis within a single solver. No separate modules for complex analysis types.

Integrated design checks

Steel, concrete, timber and cold-formed design modules run directly on your analysis results. No exporting, re-entry or version mismatches.

Detailed calculation reports

Every formula, design check and
reference is shown in full, so you can defend every number, not just the result.

What SkyCiv Truss and Frame offers

Capabilities for modelling and analysing simple to complex structures.

Full hand calculations

SkyCiv 2D Truss also comes with full hand calculation features – which clearly show the step-by-step calculations for both the method of joints and the method of sections. This interactive learning module helps students follow the hand calculations of how to solve a truss:

  • Step 1: Model your truss in S3D using the Truss Builder.

  • Step 2: Click “Solve” to transition to the results section.

  • Step 3: Click the “Truss Hand Calcs” button highlighted in the image.

  • Step 4: A pop up will come up with the hand calculations.

Unlimited Loading Scenarios

Design and setup your 2D Truss Analysis with SkyCiv Trusses Calculator or SkyCiv Frame Software:

  • Add up to 10,000 Members

  • Add Unlimited Supports with full control over their restraint codes (i.e. use any support type you like)

  • Add Unlimited Point Loads

  • Add Unlimited Distributed Loads

  • Add Unlimited Moments

SkyCiv 2D Truss

  • Simplified 2D truss analysis software

  • The SkyCiv Truss Software can add 10,000 members, supports, and loads compared to the Free Truss Calculator which is limited

  • Fixities are set as pin connections (FFFFRR) for proper truss behavior

  • Add as many supports and loads as you like, SkyCiv Truss can solve in

  • The reactions at each support are solved and displayed in the Free Body Diagram (FBD)

  • Clean internal axial force results in a fast and neat diagram for use in your assignments or to check your results!

SkyCiv 2D Frame

  • Simplified 2D frame analysis software

  • The SkyCiv Frame Software can add 10,000 members, supports, and loads compared to the Free Tool which is limited software

  • Fixities are set as fixed frames (FFFFFF)

  • Results for: Reactions at supports, bending moment, shear and axial forces

  • For all other results, users can use SkyCiv Structural 3D which comes with all subscriptions

  • Add cross-section properties using SkyCiv Section Builder

  • Fast and neat diagrams will be produced for use in your assignments or to check your results

Save, load and share your files

Truss systems and frames can often take a long time to set up. Continually entering the same structure every time you want to test it is a pain. That’s why the SkyCiv Roof Truss Calculator and Frame software allows you to save and load from your cloud storage.

Since our software is on the cloud, you can also share and collaborate on models with your team in real-time. Work as a team, or across multiple devices, with SkyCiv’s cloud truss and frame analysis software.

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 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.

Managing Director of Struct-Sure Limited

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.
