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 export our project to LIRA-SAPR, analyze scheme and import results of reinforcement to LIRA-CAD.

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

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

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 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, how to perform following operations - setting restraints on nodes, setting restrains on 1-node finite elements...

In this video guide, we will start the creation of multi-storey building.

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

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 video shows new type of load in LIRA-CAD: Special load. In this video you will learn what is special load, how to apply it and in what situations it is needed.

For various purposes it can be useful to model the soil pressure on the basement walls. The commands necessary for this purpose are presented on the "Create" tab, "Loads" panel.

In this video guide, we will set the appropriate data for further analysis.

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

This video shows how to apply seismic load by accelerogram in LIRA-CAD.

This video shows how to create and edit moving loads and combination of loads.

This video shows how to create and apply soil pressure to basement walls.

The LIRA-FEM version 2025 will use a different protection from Wibu-Systems AG, a German business. The page provides setup instructions for the CodeMeter network license server along with general details about key types.

Recommendations for the optimal computer configuration for the LIRA-FEM program in terms of price/quality. Relevance as of December 2024.
