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).


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.


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.


In this video there will be introduced new features in SAPFIR 2022. We will discuss automatic load generation on beams though proxy objects.


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).

Element Type Assignment

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


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...

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.


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


Let us consider an example of analysis of heat transfer of a brick house external wall.

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.


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

Snow mound in SAPFIR 2022

This video shows how to collect snow load automatically and to apply snow mound in LIRA-CAD.


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.


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.


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