METHOD OF DETERMINATION OF FIRE RESISTANCE OF STONE WALLS OF BUILDING Russian patent published in 2009 - IPC G01N25/50 

FIELD: physics; measuring.

SUBSTANCE: invention concerns to field of fire safety of buildings. Trial of non-reinforced stone walls and building bafflers spend without fracture on a complex of individual exponents of quality, estimating quantity of an actual limit of fire resistance on losses of the integrity bearing and heat-insulating abilities. Spot the geometrical sizes of stone walls, requirements of walls support and fastening, buckling coefficient, exponents of density, humidity thermal conduction, heat capacity and thermal diffusion of a material of a stone wall; quantity of standard loadings at trial for fire resistance and a degree of a voltage of dangerous sections of stone walls. Limit of fire resistance of non-reinforced stone walls spot on nomographic charts.

EFFECT: determining of fire resistance of non-reinforced stone walls without natural thermal action, raising of reliability of not destroying trials and reducing of economic expenses.
