Cloud-based Structural Analysis and Design Software

SkyCiv Structural 3D is our most powerful online structural analysis software, offering a full suite of modelling, Finite Element Analysis (FEA) and design capabilities.

This 3D frame analysis software allows you to model, analyze, and design steel, timber, concrete and general structures. The 100% cloud-based engineering software allows users to access their programs and files from a web browser, anywhere, anytime!

No installation is required and updates are automatic so everyone is working on the latest version of the software. Structural 3D has an intuitive user interface which allows for rapid creation of complex structural models.

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.

  • Select from 15+ template shapes including I-beam, HSS, Channel, etc.

  • Access cold rolled shapes such as AISI and AS libraries.

  • Create custom and built-up sections or import DXF files directly.

  • Perform operations such as rotate, mirror, translate, cutout, and more.

  • Calculate complex geometric properties such as moment of inertia, centroid, shear, section moduli, torsion and warping using powerful FEA.

  • Perform analysis on your sections to calculate stress values.

An Effortless User Interface

SkyCiv’s mission is to make complex engineering tasks simple and intuitive. This starts with a user-centric interface. We have a range of features designed to make using Structural 3D a breeze:

  • Create models using our intuitive pen tool or Excel-like datasheet entry.

  • Import models from Revit, Grasshopper, DXF, IFC and other structural modeling software.

  • Access range of right-click and operation functions, such as splitting members, copy-paste, multi-edit, intersecting members, area load functionality, and more.

  • Simple input fields with detailed info tips and links to video tutorials.

  • Create vertical and horizontal gridlines to accelerate modeling.

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.
