Heat transfer analysis is a very important part in determining the fire resistance of a structure.


Accounting of earthquake effect assumes that the structure resists passively through the combination of strength, deformation and energy absorption. The damping level of such a system is usually very low and therefore the energy dissipation value of such a system in elastic behavior is also low. During the strong earthquake the def...

Heat Transfer Analysis

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-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.


Let us consider an example of analysis of heat transfer of a brick house external wall.
