Packing a model

In the process of creating a model, sometimes user has to repeatedly delete some elements and then add others.


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


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.


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


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


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


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.

LIRA-SAPR: design option test


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


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.

Special loads in SAPFIR 2022

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.


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.

Soil pressure

Soil pressure

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.

Earthquake loads in SAPFIR 2022

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


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.


Thermal loads

Thermal loads

The article describes how to model thermal loads in SAPFIR. To model the thermal loads in LIRA-CAD module of the program, use the specialised tools available on the "Analytics" tab, on the "Analytical load" panel, in the "Loads" drop-down list.


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