LUSAS Civil & Structural / LUSAS Civil & Structural plus

LUSAS Civil & Structural is a world-leading finite element analysis software application for the analysis, design and assessment of all types of structures above and below ground.

Whether you need to carry out a straightforward linear static analysis of a simple structural frame, a dynamic analysis of a masonry or concrete building, or a detailed geometrically nonlinear staged erection analysis of a cable stayed structure, LUSAS Civil & Structural provides all the facilities you need.

Many real-life illustrative uses of the software can be seen by visiting the civil and structural case study page.

Why use LUSAS Civil & Structural?

  • Benefit from the use of cost-effective structural modelling and analysis (including soil-structure interaction) of any structure in one software package, and then extend your workflow into design.
  • Build global and local models that are feature-based and allow mixing of element types in the same model. 
  • Carry out advanced nonlinear geometry, material and contact modelling.
  • Customise the software to your needs using the LUSAS Programmable Interface.
  • LUSAS is a long-established and trusted provider to industry leaders, and LUSAS Technical Support is stated, by its users, to be simply: "The best in the business."

Use it for global analysis of all types of structures...
  • Building frames / Space frames
  • Simple / complex slabs
  • Masts / towers
  • Grandstands / stadia
  • Storage tanks / silos
  • Cooling towers / chimneys
  • Dams
  • Docks / piers / jetties
  • Tunnels / retaining structures
  • Caissons / gravity base structures
And use it for:
  • Innovative new design
  • Cost-saving re-designs
  • Cost-effective structural assessments
  • Ultimate load assessments
  • Development of retrofit solutions
  • Erection and demolition engineering

Some Civil and Structural application areas

Software products

LUSAS Civil & Structural is available in a choice of software levels; Civil & Structural LT, Civil & Structural, and Civil & Structural Plus to suit your analysis needs. Each uses the same Windows user interface, and has modelling wizards, comprehensive loading facilities for easy and rapid model generation, load application and combining of loadcase results for design checking. 

  • Because all levels of the products use the same user interface and terminology, training costs can be minimised and users can be introduced to LUSAS at the most appropriate level for the work they need to do. 

  • There is also full data compatibility across the product range allowing easy migration of a model to a more advanced analysis when required without any data conversion or remodelling.

  • Separate details list the capabilities of each particular software product. See how the products compare.


  • Use Civil & Structural LT for linear static analysis of structural frames and grillages. 

  • Use Civil & Structural for linear static and linear modal dynamic analysis of shell and solid models. 

  • Use Civil & Structural Plus for more advanced analyses using the appropriate purchased option(s).
