Procedure for checking the requirement referring to fire insulation capacity of a non-structural wall from the fire compartment

Abstract

The work presents the procedure for checking the capacity of a multilayered non-structural wall belonging to the fire compartment to satisfy the required insulation capacity, according to Code 7771-67.
The problem involves a complex analysis of a non-stationary conductive heat transfer. The temperature distribution at different moments and in different, characteristic sections of the element is obtained by using the finite element method. The problem of non–stationary state is solved by using the technique of direct numerical integration, step by step
