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.
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.
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.
Additional special solvers and graphic modules
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.
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.
