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


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.


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.

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.


Master class from our chief engineer about possibilities of model creation in LIRA-FEM program. You will learn how to generate simple geometry in SAPFIR GENERATOR System.

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.


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


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.
