The Difference between a Steel Section's Major and Minor Axis and Why it's Important

In this video, we compare the differences between major and minor axis and explore the effects this can have on your structural analysis model.
A section's Major axis (also known as its Strong axis) is the direction in which the section is the strongest and should be loaded in if it is designed correctly. This axis is capable of taking higher forces as it has more bending moment capacity. On the other hand, a section's Minor Axis (also known as a Weak Axis) is perpendicular to this axis and is much weaker in nature - as it is not designed to take as much force in this direction.
We also explore how the axis orientation can drastically alter the results in your analysis model - demonstrating why understanding this subtle difference is so important in structural engineering.

Unrelated to this video, but wondering if you have any plans to implement fully BIM modelling ion your software in the future? Such as Tekla? For example of connections of steel members can be modelled directly in Structural 3D and then the FEA analysis to be done in the same environment, it would be a huge achievement! You already have the FEA capability in your software suite.

Hi there! Yes we currently integrate with IFC and Revit (.rvt) files to support BIM. You can learn more on this here:
skyciv.com/integrations-and-add-ons/revit-skyciv-integration/
After importing, you can run Repair Model, as sometimes importing models from BIM might have some disconnected members, duplicate nodes etc.. After that, you can apply loads and run full FEM and Design Checks in the software. After that, you can export the model back out to Revit to complete the BIM process.
Hope this helps and feel free to shoot through any questions you have :)
