Result viewing
- Viewing of results for all or selected parts of model
- Deformed mesh plots
- 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

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.
