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.


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.


In this video guide we will talk about analysis results, namely: Deformation of scheme, Displacements in nodes etc.


In this video guide we will perform coordination for local axes of finite elements for correct display of analysis result. Also, we will get acquainted with sign convention in Lira-SAPR Help.


In this video guide, we will learn, how to perform following operations - setting restraints on nodes, setting restrains on 1-node finite elements...


In this video guide, we will learn main types of stiffnesses of finite elements, which are used in analysis in Lira-SAPR program.


In this video guide, we will learn main loads on nodes and elements, which are used in analysis in Lira-SAPR program.


In this video guide we will learn main finite elements, which are used in analysis in program Lira-SAPR.


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.


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


This tutorial illustrates options of the Fragmentation command for the comprehensive detailed visual examination and possible modification of design model as well as for the evaluation of analysis results


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.


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.

Element Type Assignment

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


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.

Information about model components

In LIRA SAPR, a command Information about nodes and elements can be found on the Select toolbar. It allows not only to get the full information about all components of the model but also to edit many of them.

Restraints Assignment

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.


To run any command on objects included in the design scheme (deletion, stiffness assignment, application of loads, etc.), first of all you must point to the corresponding objects by selecting them from the general scheme. To delete the object, it is necessary to indicate it (further, the operation of selecting model objects will be...


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).


From version 2016, the user could use templates in the Report Book in order to facilitate generation of documents and speed up this process. Figure 1 demonstrates the 'Steel truss' template that includes 3 chapters and 14 elements.


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...


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.
