Rail infrastructure modelling

Rail infrastructure modelling

LUSAS provides a comprehensive range of facilities to let you model all sorts of rail infrastructure .

Rail infrastructure capabilities

Rail load optimisation

 

  • Generate the most critical rail loading pattern for a selected track layout, for each influence shape under consideration. 

 

 

  • Watch this short video to see how to carry out a train/rail load optimisation analysis on a two-span box beam bridge that is modelled using shell elements.  (Version 18.0)

Rail Track-Structure Interaction

 

  • Parametric approach to track, structure and load modelling
  • Creates models in accordance with codes including UIC 774-3 and various Eurocode national annexes guidelines
  • Includes checks for vehicle acceleration and braking, temperature
  • Detailed standardised results reporting

Soil-Structure Interaction

  • Soil and structure modelling in one software package
  • Applicable to any bridge and tunnelling SSI problem
  • Available in both 2D and 3D and incorporating time phases
  • Models soil phenomena including stability, sliding, consolidation, seepage and dynamics

Detailed Rail Bridge Assessment

 

  • Detailed modelling of rail structures for linear and nonlinear assessment procedures
  • Local and global, linear and non linear buckling capability
  • Advanced analysis capabilities can help derive increases in assessed capacity and thus reduce cost of remedial works

 

Rail Break Analysis

 

  • Detailed modelling of rail, fasteners, superstructure and structure
  • Gap control calculation following break
