In LIRA-SAPR 2019 there is a new option to simulate the steady and transient heat transfer process.
Heat transfer analysis is a very important part in determining the fire resistance of a structure.
Let us consider an example of analysis of heat transfer of a brick house external wall.
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-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.
