Step-by-step guide for novice users of the LIRA-FEM software, which reveals the basics of finite element analysis.

Rhino/Grasshopper and SAPFIR module will interact directly through this plugin to create and edit the BIM model. It may be done with Grasshopper visual script interface. The live and associative interaction allows the user to create projects of different complexity.

Within the framework of building information modeling (BIM) concept, two-way integration of Autodesk Revit - LIRA-FEM - Autodesk Revit is implemented.

The construction of finite element meshes is an important stage of solving the problem of determining the SSS of structures. This stage is associated with satisfaction of a number of contradictory requirements.

Step-by-step guide that describes the full cycle of building design, namely creation of architectural model, its conversion into an analytical model, analysis and design, issuance of design documentation by using LIRA-CAD and LIRA-FEM software packages.

Accounting of earthquake effect assumes that the structure resists passively through the combination of strength, deformation and energy absorption. The damping level of such a system is usually very low and therefore the energy dissipation value of such a system in elastic behavior is also low. During the strong earthquake the def...

LIRA-FEM plugin in Revit helps our users to transfer model directly to LIRA-FEM or via SAPFIR, perform analysis and return reinforcement results back in Revit.

Step-by-step guide for novice users of the LIRA-FEM software, which reveals the basics of finite element analysis. In this videoguide you will learn how to create and analyse the model of steel tower in LIRA-SAPR.

Master class from our chief engineer about possibilities of model creation in LIRA-FEM program. You will learn how to generate simple geometry in SAPFIR GENERATOR System.

Step-by-step guide for novice users of the LIRA-FEM software, which reveals the basics of finite element analysis. In this videoguide you will learn how to create and analyse the model of steel frame building in LIRA-SAPR.

Suppose we have to make the automatically generated PR types come from the LIRA-CAD module to the LIRA-FEM program; in these PR types, the reinforcement pattern is arranged in two layers.

Step-by-step guide for novice users of the LIRA-FEM software, which reveals the basics of finite element analysis. In this videoguide you will learn how to create and analyse the model of RC monolithic building in LIRA-SAPR.

LIRA-FEM software imports construction axes, walls, slabs, columns, and beams from DXF text files. To import these objects to the application, they should be represented by a specific object and belong to a layer with a predefined name.

In this video guide, we will arrange reinforcement in the slab.

Heat transfer analysis is a very important part in determining the fire resistance of a structure.

This videoguide answers the questions: What is stiffness? How to add and assign steel and reinforced concrete (RC) stiffness?

Dynamic link with other programs through DXF, IFC and SAF formats. Generator system for simulating complex structures. SAPFIR plug-in to Rhino and Grasshopper. BIM integration between SAPFIR and Allplan through IFC format.

This videoguide answers the questions: What is load case and how to assign loads?

This paper explores two main methods of running LIRA-FEM on a Mac: virtualization through Parallels Desktop for M-series processors and using Boot Camp for Macs with Intel processors. We will go over the benefits and drawbacks of each approach. Finally, we'll include a detailed installation tutorial for LIRA-FEM using Parallels...

For the first time designers can use the given real arrangement of reinforcement as for calculations of physical, geometrical and engineering nonlinearity, and for check of bearing capacity of sections of bar and plate elements according to operating normative documents.

In heat transfer analysis, temperature in analytical model nodes is unknown (similar to displacement in structural analysis). Consequently, the equilibrium equation may be written as

LIRA-FEM program makes selection and check of the reinforcement according to reduced parameters of concrete and reinforcement during the specified time period when the fire load is applied.

The "Moving load" tool is mentioned to specify traffic loads on different types of structures: stylobate pavement, floor slabs of parking, bridge structures, motorways, etc.

This is one of webinars series presented by LIRALAND for LIRA-FEM structural analysis software.
In this recorded webinar, we review BIM integration on the base of IFC file from REVIT.

Options for quick generation of large panel building. The 'Joint' tool and its functionality in SAPFIR module of the program. Special features for analysis of large panel building.

Automatic generation of wind load according to Building Code. The positive and negative wind pressure is generated on the example of a multi-storey building with account of different parameters (wind region, terrain category, constructional and aerodynamic coefficients).

After the installation of the LIRA SAPR application on your personal computer, launch it by left mouse double-clicking on the shortcut icon (during the installation keep the path to the Program Files folder as suggested by default C:\Program Files\LIRA SAPR\LIRA SAPR 2020).
