The implementation of LIRA-FEM software in bridge constructions analysis (in russian)
The modern releases of LIRA-FEM software complex offer wide analysis and design opportunities for bridge structures of different systems.
Bridge analysis software
LIRA-FEM is suitable for bridge analysis. In LIRA-FEM it is possible to model and perform analysis of bridge structures
- Finite element analysis
- Static analysis
- Dynamic analysis
- Nonlinear analysis
- Seismic analysis
- Design combinations
- Frame analysis
- Beam analysis
The bridges analysis
The bridge model in SAPFIR
LIRA-FEM software has a wide functionality for dealing with a huge number of tasks, including the analysis and design of different bridge structures. The models of bridges can be created by finite elements in LIRA-FEM, or with the help of module SAPFIR-Generator.
Moving loads in SAPFIR
In LIRA-FEM software with the help of SAPFIR preprocessor there is the ability of moving load modelling. You can choose a transport facility (TF) in the program library, or create any user-defined TF and the rule of its movement in the new library.

LIRA-FEM user's projects in the field of "Bridges"
The railway bridge over the Karacum river
The railway bridge span is 110 m, with welded elements of closed sections and mounting joints on high-tensile bearing-type bolts. The main span structure trusses are 15 m high. The distance between the axes of the main trusses across the bridge is 5,8 m.
