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).

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

In LIRA-SAPR 2019 there is a new option to simulate the steady and transient heat transfer process.

Heat transfer analysis is a very important part in determining the fire resistance of a structure.

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...

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.

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

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.

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.

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).

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

In heat transfer analysis, temperature in analytical model nodes is unknown (similar to displacement in structural analysis). Consequently, the equilibrium equation may be written as
