FIELD: measuring technology.
SUBSTANCE: invention refers to research of structural unit material analysis. In the method, building inspection is supplemented with examination of heat parametres of concrete, instrumental measurement of concrete frame geometry, estimate of heating conditions of the cross-sections, and thickness determination of disturbed concrete layers. Duration of the natural fire is determined by the intensity zones reduced to thermal action of the standard fire tests of building units.
EFFECT: reliable estimate of key destructiveness parametres of the previous fire, ie duration of fire action and maximum temperature, lower labour input and reduced time of inspection of the thermally damaged concrete frames.
