BIM technology in LIRA-FEM software

Design model is generated according to the architectural model in terms of analytical concepts. BIM technology in LIRA-FEM helps engineers minimize the number of errors due to repeated data entry, improve efficiency of collaboration between related departments, coordinate design activities and reduce time losses.

Two-way integration with Autodesk Revit

Analytical model is imported from Revit to LIRA-FEM
  • A set of families and tools to generate the analytical model in Autodesk Revit; the model is as close as possible to LIRA-FEM design model.
  • Analytical model is imported from Revit to LIRA-FEM program where the strength analysis will be carried out.
  • Reinforcement selected in LIRA-FEM program is exported to Revit in order to design RC load-bearing slabs, walls, columns and beams.
  • A set of tools for graphic visualization and check of reinforcement; these tools are familiar to LIRA-FEM users but they function in Revit environment.

Two-way integration with Tekla Structures

Two-way integration with Tekla Structures
The Tekla Structures meshed model may be directly transferred to the VISOR-SAPR module. Analytical model is transferred including bars, plates, hinges, restraints and loads. So, the steel frames may be successfully transferred for analysis. In case the structure includes RC elements, it is recommended to transfer data to the LIRA-CAD preprocessor to set up the triangulation options and generate the FE model in LIRA-CAD. When all the necessary data is defined in LIRA-FEM, it is possible to carry out the static and dynamic analyses, check / select sections of steel elements and transfer them back to Tekla Structures. For RC elements, you can arrange the reinforcement in Design of RC structures module according to reinforcement selected in VISOR-SAPR. Then the rebar pattern may be transferred to Tekla Structures.

Plugin Rhino-Grasshopper - LIRA-CAD

Integration Rhino_Grasshopper_SAPFIR

Rhino / Grasshopper and LIRA-CAD may communicate directly through this plugin to generate and manage the BIM model in the Grasshopper visual programming interface. As the integration procedure is associative, it enables the user to generate models of different complexity. When the algorithm in Grasshopper is modified, the model in LIRA-CAD is dynamically modified as well as the meshed model.

Integration via IFC

Integration via IFC

Updatable IFC

Generator with the node for import of IFC model enables you to generate an updatable IFC file. When modifications are made in the source program, it is possible to overwrite the IFC file and then update these IFC files in the LIRA-CAD model.

Standard integration

Import one or several IFC files into one project. Import of files in IFC2x3 and IFC4 format. It is possible to convert some types of objects into others, replace IFC materials with LIRA-CAD materials with design parameters defined for analysis of reinforcement.

Integration via SAF

BIM integration ArchiCad_SAPFIR

Integration with the ArchiCad and Allplan analytical model via SAF (Structural Analysis Format). Data exchange is carried out via a * .xlsx file, that may be opened in MS Excel, where you could either review it or modify. Model geometry, sections, SAF materials may be transferred via SAF. You can comply the cross-sections and materials in ArchiCAD and LIRA-CAD with the SAF translator.

More about integration via SAF

SAF and IFC files are imported from Archicad to LIRA-CAD. Settings of the analytical model in Archicad. Settings to comply materials and shapes assigned in Archicad to the materials and sections that are used in LIRA-CAD. Eccentricities for beams. In addition to the load-bearing frame transmitted via SAF format, information for loads may be transferred via IFC file to LIRA-CAD (internal partitions, external fences and premises).

Integration via DWG/DXF

Import of floor plans

Updatable DWG

BIM model is generated in Generator according to the DWG drawing; element thicknesses and section dimensions are recognized automatically. When the DWG underlay is modified, the whole model generated on the underlays may be updated dynamically.

Standard integration

Floor plans are imported into LIRA-CAD. Each layer is assigned the type of object that this layer will create in LIRA-CAD. You can obtain sections and thicknesses of elements from the DWG file if the objects were generated along the contour. It is also possible to assign these parameters directly during the import to LIRA-CAD.

Importing a DWG file as an underlay

DWG file is imported into LIRA-CAD solely for indicating dimensions when the new objects are generated.

Integration with Plaxis

Intergation between LIRA-FEM and Plaxis
LIRA-FEM and Plaxis are integrated with the PSI converter. So, the model generated in LIRA-FEM may be analysed together with the soil model generated in PLAXIS-3D. There are 3 options for integration: 1) displacements of support nodes of the structure are transferred from PLAXIS-3D to the LIRA-FEM model as the load case with specified nodal displacements; 2) according to analysis results in PLAXIS-3D, the stiffness of the soil foundation (subgrade modulus C1) in the LIRA-FEM design model is changed and the soil pressure loads are transferred from PLAXIS-3D to LIRA-FEM (optionally); 3) according to the analysis results in PLAXIS-3D, the stiffness of the soil foundation is not changed, but additional loads are applied.
