"Bridge" system is used for structures analysis for the following moving loads:
- wheeled transport loads;- pedestrians loads;- oversized wheeled vehicles loads;- metro and tram rolling stock loads.
Soil
"Soil" system is designed for automatic evaluation of variable in plan bedding values under foundation slab. In SP LIRA 10.4, besides graphical interface improvements, bedding values evaluation time was dractically reduced due to processor's multithreading usage.
Variation of models
There was added a new feature of uniting obtained internal forces and displacements received upon loadings in different problem cases with further DCF and DCL calculation. Given opportunity allows adequate evaluation of specific load combinations.
Pushover Analysis (nonlinear static method)

This method connects bearing capacity, given as relationship between displacement of top of the structure and shear force in foundation, and seismic requirement given as a response spectrum. Intersection point of bearing capacity curve and response spectrum curve - dynamic equilibrium - is evaluated and it's used for evaluation of expected behavior of the structure.
Finite elements with intermediate nodes on sides/edges
There were implemented new finite elements with intermediate nodes that allows to obtain greater problem solution accuracy compared to similar elements without intermediate nodes with equal number of variables.

Interaction between Autodesk AutoCAD and SP LIRA 10.4 is realized via "Import from *.dxf", "Floor plans import from *.dxf" and "Export to *.dxf" commands.
"Import from *.dxf" allows to import readymade finite element model saved as .dxf file into SP LIRA 10.4.
"Floor plans import from *.dxf" gives the opportunity for floor plans import into LIRA 10.4 architectural elements followed by its triangulation by LIRA's tools.
"Export to *.dxf" allows export from LIRA 10.4 to .dxf file of not only design model initial geometry but also deformed model, deformation, internal forces and stresses mosaics and isofields, etc.
Interaction with other graphics and analysis systems is based on the following file formats:
*.msh; *.stl; *.obj; *.mesh; *.off; *.poly; *.dxf; *.igs; *.3ds; *.neu; *.byu; *.ifc
Interaction with other documentation systems is based on the following file formats:

Main innovations in SP LIRA 10.4 R4.0
- Added export of architectural model to ifc format, which leads to two-way interaction with Tekla Structures.
- OpenGL version has been updated to 3.3 for new rendering algorithm of design model. Thereby, operations with large-scale models became even simpler and faster.
- For cross sections analysis considering bending torsion, there was added 5 new loading types, utilized in model feature 7. Added an opportunity to perform displacements unification by W (warping) for model feature 7. Bending torsion may have a significant influence on steel thin-walled bars of open profile, such as I-beam (symmetrical or asymmetrical) and channel bar. Bending torsion comes with bending of certain parts of cross section. For example, horizontal bend of each flange in opposite directions takes place during torsion of I-beams (with vertical web and horizontal flanges). Two oppositely directed bending moments form flexural-torsional bimoment, and its value defines bending torsion.
- In results conversion mode, there has been added a consideration of architectural elements, so users can promptly pass out to other software not only geometry changes, but cross sections changes, that were passed out manually earlier.
- Significantly expanded steel gauge database, added more than 20 new gauges.
