Computer Aided Structural Analysis

  • The single interactive window is the hub of the program and will be familiar to users of our mobile Apps.
  • Very few controls means that the program is easy to understand and quick to use:
  • Simple mouse gestures to pan and rotate, and structures can be created entirely with the mouse.
  • Multiple windows can be opened of the same model:
    • View or work on two close-up areas simultaneously.
    • Work in one window while showing another on a second monitor or projector.
    • View results while editing geometry and/or loading.

  • Nodes and members are selected by simply pointing and clicking.
  • Selected nodes can be moved by dragging with the mouse or double-clicking on their coordinates.
  • Selected members can have their lengths changed by dragging their ends with the mouse or by double-clicking on the printed length.

  • Geometry can be placed into groups.
  • Each group can be colour-coded, including being translucent.
  • Groups can be removed from the analysis:
    • “What if?” analysis.
    • Depiction of surrounding structure for context or location.

  • Members can be drawn to scale with their actual cross-sectional shape.
  • Rendered views depict group colours.
  • Individual groups can be picked out, with other groups shown ghosted.
  • Viewpoints can be stored and recalled for quick visual positioning.

  • The loading tab is for viewing and editing applied loads.
  • The displayed scale of the loads can be adjusted with the slider in the top right-hand corner.
  • Loads are selected by simply pointing and clicking.
  • Selected loads can have their magnitudes and positions changed by simply dragging the arrows with the mouse.
  • To enter values numerically, double-click on a number and a calculator will appear for a new value.
  • To invert a load, simply negate its value or drag it to the other side of the member.

  • Loads are assigned to load-cases.
  • Multiple load-cases can be created and named.
  • Gravity loading is automatically determined.
  • Combinations allow summation of factored load-cases.


Screenshot
  • All numerical input to the program is via a calculator like this.
  • It can be operated with the mouse or keyboard.


Screenshot
  • Results are automatically calculated in the background as the model is edited.
  • Nodes and members can be interrogated by clicking on them.
  • Global displacements and member stresses are displayed at the top of the window.
  • For member deflections, bending moments, and shear forces, a slider reads out the values at any point.
  • Black dots can be clicked on for automatically determined points of interest such as maxima and discontinuities.


Screenshot
  • The utilities window complements that of our mobile Apps.
  • The preferred unit system can be chosen.


Screenshot
  • The section library will be familiar users of our mobile Apps.
  • A wide range of sections is presented.
  • A custom section generator of common shapes is provided.


Screenshot
  • A custom section generator of common shapes is provided.
  • Simply pick the shape and double-click on the dimensions to edit.
  • The section can be rotated through 90° by clicking on “Rot”.
  • Choose a material from the library by clicking on the material button.
  • When done, click on “Use” to apply to the selected members.


Screenshot
  • Graphical reports can be printed or saved as PDF.
  • Emphasis on visual location and interpretation.
  • Multiple report formats can be created.
