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 processThanks to two-way integration, analyses are now part of a single information model
- Autodesk Revit
- Tekla Structures
- PLAXIS 3D
- Rhino-Grasshopper
- IFC, SAF, DXF
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- 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- 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- 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
Assemblage
simulates erection process with account of changes in structural model during assemblage, accumulation of dislocation stresses, changes of material properties in time, etc.
Bridge
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
KM
automatically generates working drawings KM (of steel structures) – tagged models, joints, specifications (only in Russian)
Soil
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.
RC Design
automatically generates sketches of working drawings for columns, beams, diaphragms, floor slabs by results of analysis of reinforcement in ARM 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
Generator
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
