METHOD OF DETERMINING FIRE RESISTANCE OF STONE PILLARS WITH STEEL BECKET Russian patent published in 2015 - IPC G01N33/38 

FIELD: fire safety.

SUBSTANCE: testing of stone pillars with steel becket is conducted without destroying on the complex of individual quality indicators, assessing the value of the actual fire resistance limit on load-bearing capacity loss. To do this, the geometric dimensions of the stone pillars with steel becket is determined, as well as bearing conditions and the structure heating, the value of buckling coefficient, values of density, moisture content, thermal conductivity, heat capacity and thermal diffusion of the material of stone pillars with steel becket, the percentage of reinforcement with connecting plates of the steel becket; the value of standard loads in testing the fire resistance and the degree of tension of dangerous cross-sections of the stone structure. The fire resistance limit of stone pillars with steel becket is determined by the polyparametric mathematical relationship.

EFFECT: reduction of labour intensity, improvement of accuracy, fidelity, informativeness, and acceleration of tests.
