Rectangular plate simply supported at three corners and subjected to an out-of-plane concentrated load and concentrated moments

Rectangular plate of constant thickness, clamped along the perimeter, subjected to a temperature load

Two-rib beam subjected to uniformly distributed loads applied in the plane of the ribs

Cylindrical shell with free ends under a temperature gradient through its thickness

Cylindrical body, free from restraints, subjected to a uniform longitudinal load distributed over the ends

The square panel in a flat‑slab structure, rigidly connected to a column of circular cross‑section, under a uniformly distributed transverse load

The stress state of a triangular dam of unit thickness in Cartesian coordinates under the self weight and hydrostatic pressure

The stress–strain state of a ring plate (subjected to a uniformly distributed transverse load) with hinged supports.

The LIRA-FEM version 2025 will use a different protection from Wibu-Systems AG, a German business. The page provides setup instructions for the CodeMeter network license server along with general details about key types.

This paper explores two main methods of running LIRA-FEM on a Mac: virtualization through Parallels Desktop for M-series processors and using Boot Camp for Macs with Intel processors. We will go over the benefits and drawbacks of each approach. Finally, we'll include a detailed installation tutorial for LIRA-FEM using Parallels...

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.

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 "Moving load" tool is mentioned to specify traffic loads on different types of structures: stylobate pavement, floor slabs of parking, bridge structures, motorways, etc.

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.

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.

LIRA-FEM plugin in Revit helps our users to transfer model directly to LIRA-FEM or via SAPFIR, perform analysis and return reinforcement results back in Revit.

This is one of webinars series presented by LIRALAND for LIRA-FEM structural analysis software.
In this recorded webinar, we review BIM integration on the base of IFC file from REVIT.

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