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

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 SAPFIR-3D and LIRA-SAPR software packages.

In Tekla Structures it is possible to generate analysis model that includes bars, plates, loads and boundary conditions. LIRA-SAPR program supports two-way integration with Tekla Structures.

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...

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

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

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

Step-by-step guide for novice users of the LIRA-SAPR 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.

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

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.

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

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

This videoguide answers the questions: What is offsets and how to assign them to bars?

In LIRA-SAPR 2019 there is a new option to simulate the steady and transient heat transfer process.

Step-by-step guide for novice users of the LIRA-SAPR 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.

Step-by-step guide for novice users of the LIRA-SAPR 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-SAPR 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.

This video demonstrates the procedure for coordinating the local axes of plate elements. This procedure allows to obtain forces and stresses oriented with respect to the coordinated local axes as a result of the analysis.

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

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.

LIRA-SAPR 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.

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

New document system Report Book includes interactive screen copies of design model and conceptually new tables with output data from FEA and analysis of RC structures. When you save the screen copy, the state of design model is saved together with the image presented on the screen. It is possible to return the model to this saved v...

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).

In LIRA-SAPR 2018 it is possible to analyse the fibre-reinforced polymer (FRP) rebars according to DSTU-H B V.2.6-185:2012. Analysis of reinforcement is carried out according to DBN V.2.6-98:2009.

Copy by parameters, copy by rotation, mirror copy, copy by one node

The construction being designed should be fixed in the space, so the user should select the nodes to be fixed and the directions they should be fixed.

In the 2014 version we developed new ribbon interface styles: "Ribbon RC", "Ribbon Steel", "Ribbon plus". It simplifies the handling process with design scheme and provides a simpler and more intuitive scheme positioning in the workspace.

In this video guide, we will learn the interface of the program LIRA-SAPR, and also perform the calculation of the beam on two supports with a uniformly distributed load.

In this video guide, we will complete the creation of architectural model of multi-storey building.

After creating a model, it is recommended to check the type of elements.
