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.

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.

Dynamic link with other programs through DXF, IFC and SAF formats. SAPFIR-GENERATOR system for simulating complex structures. SAPFIR plug-in to Rhino and Grasshopper. BIM integration between SAPFIR and Allplan through IFC format.

Options for quick generation of large panel building. The 'Joint' tool and its functionality in SAPFIR module of the program. Special features for analysis of large panel building.

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.

Rhino/Grasshopper and SAPFIR module will interact directly through this plugin to create and edit the BIM model. It may be done with Grasshopper visual script interface. The live and associative interaction allows the user to create projects of different complexity.

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

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

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

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

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

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.

In Tekla Structures it is possible to generate analysis model that includes bars, plates, loads and boundary conditions. LIRA-SAPR program supports two-way integration with Tekla Structures.

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).

Copy by parameters, copy by rotation, mirror copy, copy by one node

METEOR (Method of unified complete result) Enhanced options for MODEL VARIATION system.
New system that enables the user to merge problems with the same topology ' nodal coordinates, FE model, geometry of sections. Problems may differ in load cases, stiffness and boundary conditions. The merged problem will contain topology,...

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.

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.
