METHOD OF DETERMINATION OF FIRE RESISTANCE OF TRAVERSALLY REINFORCED 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 traversally 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. For this purpose determine the geometrical sizes of stone walls, heating requirements, support and fastenings of walls, buckling coefficient, percent of reinforcing of a laying on volume; exponents of density, humidity, a thermal conduction, a heat capacity and thermal diffusion of a material of traversally reinforced stone walls; quantity of a standard loading at trial for fire resistance and a degree of a voltage of dangerous sections of stone walls. Limits of fire resistance of traversally reinforced stone walls determine on polyparametric dependences.

EFFECT: determination of fire resistance without natural thermal action, increase of reliability of quality assurance and non-destroying trials, decrease in economic expenses.
