Online course "Practice of creating digital models of buildings and structures in the LIRA-CAD system"

• LIRA-CAD (SAPPHIRE) program interface. Introduction and configuration.
• Building a model in LIRA-CAD (“from scratch”, using dxf floor plans, underlays in the Generator system, import from other programs in IFC format).
• Creation of a physical (architectural) model of the frame in the LIRA-CAD preprocessor.
• Bindings, construction from L0, using auxiliary points.

2. Modeling of structural elements and joints

• Modeling of pile foundation and connection of soil model.
• Modeling of support conditions at the junction points of frame structures.
• Obtaining punching contours for beamless floor slabs.

3. Loads, impacts and standard parameters

• Assigning the necessary data for design: regulatory documents, materials.
• Creation of loads and stresses on a building: permanent, temporary, wind, etc.
• Formation of RSN combinations (calculated load combinations).

4. Formation of the calculation scheme and finite element (FE) model

• Conversion to a calculation model, detailed consideration of various settings of the calculation model.
• General principles of creating a finite element mesh (simplification of complex hole contours, etc.), creation of triangulation lines.
• Formation of a finite element model, analysis of the quality of the resulting FE mesh.
• Exporting the calculation scheme to VISOR.

5. Calculation and design of reinforced concrete structures

• Calculation of the scheme and selection of reinforcement.
• Export of selected reinforcement to the Reinforced Concrete Structures Design system.
• Creation of reinforcement for the main structural elements: slabs, walls, columns and beams.

6. Release of working documentation and summing up

• Creation of marking plans and sections.
• Obtaining 3D views of reinforcement, specifications and steel consumption lists, working drawings of reinforced concrete and reinforced concrete structures.
• Answers to questions.
