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


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


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 main loads on nodes and elements, which are used in analysis in Lira-SAPR program.


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


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


Step-by-step guide for novice users of the LIRA-FEM software, which reveals the basics of finite element analysis.


Step-by-step guide that describes the full cycle of building design, namely creation of architectural model, its conversion into an analytical model, analysis and design, issuance of design documentation by using LIRA-CAD and LIRA-FEM software packages.


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

LIRA-SAPR: design option test


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.


This tutorial illustrates options of the Fragmentation command for the comprehensive detailed visual examination and possible modification of design model as well as for the evaluation of analysis results


New document system Report Book includes interactive screen copies of design model and conceptually new tables with output data from FEA and analysis of RC structures. When you save the screen copy, the state of design model is saved together with the image presented on the screen. It is possible to return the model to this saved v...


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