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

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.

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.

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

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.

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,...
