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. 

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?

  • LUSAS Bridge provides cost-effective structural modelling and analysis (including soil-structure interaction) of any structure, in one software package. 
  • Global and local modelling is feature-based and allows mixing of element types in the same model. 
  • Advanced nonlinear geometry, material and contact modelling.
  • The software can be customised using the LUSAS Programmable Interface. 
  • Overall, 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

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.
