Analysis & graphic systems and solvers

LIRA-FEM software contains the modules of the basic configuration as well as additional systems

Basic configuration

Min time for design model generation

High efficiency in integration process
Efficient BIM

Thanks to two-way integration, analyses are now part of a single information model

  • Autodesk Revit
  • Tekla Structures
  • Rhino-Grasshopper

Components of BIM technology

Design model may be generated from the architectural model in terms of analytical concepts.


Preprocessor LIRA-CAD

Design model is generated based on 3D information model.


Intuitive GUI

Wide range of user-friendly tools to generate and analyse computer models of arbitrary structures. When solving the problem, the user works in this environment at all stages from generation of design model up to evaluation of analysis results.

Advanced FEM solver

Includes several optional modules
Finite Element Method
  • Design Combinations of Forces (DCF)
  • Design Combinations of Loads (DCL)
  • Loads on fragment of the structure
  • Stability analysis
  • Strength analysis of sections

Linear solver

static analysis, FE library, complete dynamic analysis, floor (nodal) response spectrum, earthquake, wind pulsation, super-elements


Nonlinear solver

engineering nonlinearity, physical nonlinearity, structural nonlinearity, geometric nonlinearity, pushover analysis

Metal and reinforced concrete (RC) structures

Powerful tools for standard problems
Design modules
  • Analysis of longitudinal and transverse reinforcement in columns, beams, slabs, diaphragms and shells according to the ultimate and serviceability limit states; sketches for working drawings.
  • Selection and check of rolled, compound and through sections; selection and check of joints in metal structures – joints in metal frames, truss joints (from angles, round and rectangular tubes), support joints in columns.

Reinforced concrete structures

Analysis of reinforcement (cross-section areas) according to different building codes


Local mode of reinforcement

Analysis & design of the individual RC elements according to different building codes.


Metal structures

Selection of cross-section for metal elements and check of defined sections and joints according to different building codes.


Editable steel tables

Databases of rolled and welded profiles (option to generate new database or modify existing one).

Additional systems

Additional special solvers and graphic modules

Enhanced options for specific problems
Specific features
  • Dynamic analysis
  • Design options
  • Modelling of erection, dynamic loading, progressive collapse
  • Thermal conductivity. Fire resistance
  • Analysis of foundations, panel, masonry reinforcing and composite (metal & RC) structures


simulates erection process with account of changes in structural model during assemblage, accumulation of dislocation stresses, changes of material properties in time, etc.



defines moving load (based on SAPFIR), generates influence surfaces


Time history analysis

simulates the process of dynamic loading according to accelerograms, determines forces and displacements at certain time periods, takes into account damping structures and material damping



automatically generates working drawings KM (of steel structures) – tagged models, joints, specifications (only in Russian)



generates 3D model of the soil based on engineering & geological surveys (geological boreholes) and applies generated model further in analysis of the ‘overground structure – foundation – soil’ system


METEOR system

Merges analysis results of several problems with different loads, stiffness, boundary conditions. Enhanced variant of MODEL VARIATION system.


Design of RC structures

automatically generates sketches of working drawings for columns, beams, diaphragms, floor slabs by results of analysis of reinforcement in ARM-SAPR module


Large panel buildings

generates 3D model of panel building. Makes design and arrangement of joints. Carries out linear and nonlinear analysis of structural model (nonlinear behaviour of platform joints). Evaluates analysis results and stress-strain state of joints.


Masonry structures

generates 3D model of multi-storey building from masonry structures with account of RC embedments (bond, core). Carries out analysis and selects mesh reinforcement for masonry.


Composite (RC & steel) structures

carries out analysis of composite (RC & steel) structures - columns and beams with different patterns of stiff reinforcement; selects flexible reinforcement in defined composite sections.


Cross-section Design Toolkit

Physically nonlinear analysis of arbitrary sections



System for visual parametric programming for auto generation and modification of complex 3D structures


Fire resistance

selects reinforcement for required ultimate fire resistance


Thermal analysis

simulates steady-state and transient heat transfer problems


Progressive collapse

Simulation of progressive collapse. Stress-strain state of the whole structure preceding collapse is the initial one for the further variants when destructed elements are deleted


Bar analogues

Design of elements (similar to bars) presented in design model with a set of FEs using appropriate bars
