Software Specification

Software Product Levels

LUSAS Bridge software is available in three software product levels with additional software options available for purchase to meet your particular needs. 

  • Bridge LT is suitable for linear static analysis of structural frames and grillages. 
  • Bridge is suitable for everyday linear static and linear dynamic analysis using beams, shells, solids and joints.
  • Bridge plus includes an extended advanced high-performance element library which allows for more advanced analyses to be undertaken.

All software is fully integrated and upgradeable. 

Software Options

Software options are available for some of these products and are listed at the bottom of the detailed specification listings for each product.

Which product and which options do I need?

The detailed specification for each product lists the main features and capabilities of each product. A table of products and options is also provided to assist with your LUSAS Bridge software product and software option selection for a particular modelling or analysis task.

Compatibility of LUSAS Bridge software products

Model and results files created by a lower product (such as Bridge LT) can be viewed and edited by a higher product version (such as Bridge). 

Model and results files created in a higher product can be opened for viewing or editing in a lower product version provided the model contains only those elements and analysis options supported by the lower product.

Compatibility of LUSAS Bridge software release versions

LUSAS model and results data can only be read in a particular software release version when it was written by a version with the same or lower 'major' version (such as V14 or V15), and also the same or lower 'point' release version (such as V14.5 or V14.6).
