Structural engineering software LIRALAND Group

Last updated: 1 June, 2021


  • Enhanced transfer of surface loads to VISOR-SAPR module.
  • Restored option to make a cleanup (manually) of the wall for the slab.
  • Restored option to define the snow load according to NP to SP RK EN 1991-1-3:2005/2017.
  • For the arroy of piles, it is possible to consider ratotion angle about the Z-axis that was defined in properties of the structure.
  • Enhanced option to copy storeys with stairs for which load values are defined.


  • New option to extract lines from the surface generated by formula with node 'SurfForm' - Defining the surface with formula.
  • Enhanced generation of lines in node 'JoinLn' - Connection of the specified lines in series.
  • Enhanced node 'StoreyPro' - Advanced generation of storeys at specified levels.
  • Combinations with dynamic load cases are ignored when you define the input data for fire resistance analysis (by DCL).
  • Enhanced analysis of reinforcement (with account of fire resistance) in shear force for the section with dimension >100 cm.
  • Modified generation of nonlinear stress-strain diagram for concrete for the DCF group A1 according to analysis results of reinforcement.
  • Enhanced option to assign types of pilot reinforcement (PR) to bars with account of symmetric/asymmetric reinforcement for columns and beams.
  • Modified analysis of transverse reinforcement in shear force for RC elements according to SP 63.13330.2012/2018.
  • Modified analysis of reinforcement by serviceability limit state for RC elements of circular/ring sections according to SP 63.13330.2012/2018.
  • In METEOR system, it is possible to delete several problems (at the same time) from the list of integrated problems.
  • Modified import of files *.stl, *.mesh, *.msh, *.obj, *.poly in 64-bit version of LIRA-SAPR.
  • Fixed bug: when for some imported loads the program did not compute design strength of soil at the level of load application.
  • Fixed bug in transferring loads to the SOIL system in case when number of groups of loads in *.lir file is less in comparison with the number of groups previously transferred and saved to *.sld file.
  • Analysis of reinforcement is restored for the integrated problem obtained by analysis rsults of METEOR system by DCF+.
  • Modified options to open and save RC materials for files from version 2021.
  • Fixed bug: account of local moment in analysis of truss joint.
  • Analysis of eccentrically compressed elements of I-section is modified for EN 1993-1-1:2005/AC:2009.
  • New option to use unification for the integrated problems in METEOR system ('DCF+' mode).
  • Clarified analysis by DCL for punching shear contour according to SP RK EN 1992-1-1:2004/2011.
  • When the columns base is analysed, it is possible to apply bolts with diameter 80mm.
  • Fixed bug: program failure in case you edit design model and evaluate analysis results at the same time (in different program windows).
  • Fixed bug: in saving accidental eccentricities (eak) defined for dynamic load cases.
  • In the Steel tables ('Steel Rolled Shapes' module) it is possible to save additional columns with user-defined parameters of steel for different thickness values of rolled shapes (columns 15-20 in the table).
  • In analysis of support joint of truss from rectangular pipes, clarified calculation of forces on high strength bolts.
