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-CAD, and also perform the calculation of the beam on two supports with a uniformly distributed load.


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


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


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


In this video guide, we will export our project to LIRA-SAPR, analyze scheme and import results of reinforcement to LIRA-CAD.

Snow mound in SAPFIR 2022

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


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.


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

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.


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...


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


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.


The construction of finite element meshes is an important stage of solving the problem of determining the SSS of structures. This stage is associated with satisfaction of a number of contradictory requirements.


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


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.
