Solvers and modules
Principal solvers and modules
One Intuitive Graphic Environment
Intuitive GUI contains a wide range of user-friendly tools to generate, analyse and evaluate 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. It is also possible to switch to any selected mode and obtain data from any stage as well as preview windows from several modes simultaneously.
VISOR-SAPR
Preprocessor
3D information model available in SAPFIR-3D is converted into design model. Then the user could carry out analysis and design for this design model in LIRA-SAPR program. It is possible to import 3D and 2D models generated in other graphical software: Revit, AutoCAD, Allplan, Tekla, ArchiCAD, etc.
SAPFIR-Structures
FEM solvers
LIRA-SAPR contains a set of solvers and modules that realize linear/nonlinear static/dynamic analyses of structures.
Statics Dynamics Stability
RC Structures
Analysis & design of reinforced concrete (RC) structures: options to determine areas of reinforcement for columns, beams, slabs, diaphragms and shells according to ultimate and serviceability limit states. Building codes of different countries are supported. Drawing of beams and columns are presented after analysis and can be saved as DXF files.
ARM-SAPR
Steel Structures
Analysis & design of steel structures: options to select sections of elements in steel structures (such as truss, column, beam) and to check specified sections and joints according to building codes.
STC-SAPR
RC Structures (Local mode)
Analysis & design of separate reinforced concrete (RC) bar or plate element. Design model of an element as well as applied loads may be either imported from ARM-SAPR module or defined by the user.
LARM-SAPR
Steel Tables
Steel tables with rolled and welded shapes may be either generated or modified.
SRS-SAPR (Steel Rolled Shapes)
Additional special solvers and graphic modules
Visual programming environment
Parametric modelling of arbitrary buildings and structures. Graphical editor for algorithm development; this editor applies modelling tools available in SAPFIR-3D.
SAPFIR-Generator
SOIL
3D soil model is generated according to specified geologic data (location and parameters of boreholes). Based on generated 3D model, the program automatically determines moduli of subgrade reaction, pile stiffness and assigns stiffness parameters to FE when the soil model is included into design model.
Large Panel Buildings
Structural model of the large panel building is generated. Analysis is carried out and then you could obtain parameters of the stress strain state for elements of the large panel building. Constantly enlarged and editable library of joint types is provided. This library ensures adaptability of the system to new types of large panel buildings.
Cross-section Design Toolkit
Stiffness parameters are computed: flexural, torsional, shear and warping for mono- and multi-material arbitrary sections. Sections may be solid, thin-walled and combined. Strip elements and rolled shapes may be used.
Masonry and Masonry Reinforcing Structures
Analysis of masonry reinforcing structures in LIRA-SAPR program supports the following building codes: SP 15.13330.2012, SNIP II-22-81 and DBN B.2.6-162.
Composite (Steel & RC) Structures
Analysis of composite structures in LIRA-SAPR. SP 266.1325800.2016 Chapter 7 is supported: analysis of RC structures with stiff reinforcement and analysis of pipe concrete structures.
METEOR (Method of unified complete results)
Problems with the same topology (nodal coordinates, FE model, geometry of sections) may be merged. Problems may differ in load cases, stiffness and boundary conditions.
Enhanced options for MODEL VARIATION system
ASSEMBLAGE
Computer simulation for erection of the structure. Changes in design model are traced: applying and removing of assemblage loads, imposing and removing of internal restraints.
Bridge
Analysis of bridge structures (beam, arc, guy, suspension). Influence and surface lines of forces may be obtained in the specified section from moving load.
Time History Analysis
Unlike dynamic analysis realized in linear solver based on methods of spectral analysis, this module provides time history analysis of nonlinear deformed structures, e.g. structures with one-way restraints, physically nonlinear systems that have
σ-ε
relations in the shape of Prandtl diagram.
Design of RC Structures
Module for design of RC structures. Option to obtain working drawings of reinforcement, specification of reinforcement, bill of materials and list of elements for every floor slab, diaphragm, column and beam.
SAPFIR-RC
Working drawings KM (Steel structures)
Complete set of working drawings KM (steel structures) may be obtained: erection drawings, list of elements, drawings of joints, necessary notes and specifications.
