  • Contours of displacements, moments or forces using line contours or colour fill on fleshed or unfleshed members
  • Bending moment and force diagrams for beam elements with optional peak values displayed
  • Beam stresses at beam fibre locations
  • Peak results value display
  • Stress vector plots
  • Graph plotting with export to standard spreadsheet packages
  • Animate deformed shape
  • Results window summaries
  • Copy and paste of results plots to other applications
  • Printing and plotting of results for all or selected parts of model
Software Compatibility

Model and results files created by LUSAS Bridge LT can be read by other LUSAS Bridge software products. Model and results files created by LUSAS Bridge and LUSAS Bridge plus versions can be opened for editing or viewing in LUSAS LT provided the model contains only those elements and analysis options supported by the LT version.


LUSAS Bridge LT product option

The analysis and design capabilities of LUSAS Bridge LT can be enhanced by purchasing and using the following software option:-

Steel Design

  • Design code-based results visualised as Utilisation ratios on members
  • Design summary results produced for selected members and loadcases
  • Generate formatted design reports, showing calculations made and referencing clauses and equations from chosen code.

LUSAS Bridge LT upgrade options

  • LUSAS Bridge - for linear static stress analysis, linear buckling, natural frequency analysis, linear dynamics including forced response, Interactive Model Dynamics, and fatigue analysis.
  • LUSAS Bridge plus - for nonlinear, dynamic and thermal/field analysis problems
