The paper presents results of numerical simulation and fire tests of multi-layered structures carried out under real fire conditions. It has been shown that fire test carried out according to ISO 834 standard differs from fire test conducted under real fire conditions. A new fire test methodology has been proposed. It is suggested to use real fire temperatures during fire tests to avoid accidents and allow occupants to evacuate the building safely. The ISO fire test standard should be improved visibly. Structural solutions to reduce temperatures and temperature deformations of multi-layered structures during fire are also reviewed. It was established that the gypsum layer should be placed in the middle of multi-layered structure in order to cool the structure more efficiently during fire.
