Description

Structural/Civil Engineering App for elastic analysis of general 3D space-trusses.

3D structural models can be created and analysed. There is an emphasis on quick and precise input of high-resolution data through graphical tap-and-drag interaction, with numeric input available as an alternative. Automatic concurrent analysis ensures that up-to-date results are conveniently available after every edit. Clear graphical representations of deflections and force envelopes are interactive with slider bars for reading off results at any point along the members.

Trusses have all member ends pinned to the nodes, preventing transfer of bending moments and requiring the structure to be suitably braced against collapse.

Benefits of this App over Space Truss L include automatic gravity loading, geometry groups, more advanced display capabilities, the ability to rotate and flip geometry, make selections by rubber-banding a box, and have member major axes pointing towards a third node, which allows for easier modelling of, e.g., roof purlins, rings, and other angled orientations.

  • Space-truss elastic analysis.
  • Extensive section library.
  • Custom section generator.
  • Levels 1 ~ 4 features
