Показано, что применяемый в настоящее время подход к учету начальной температуры стандартного пожара математическими формулами приводит к значительным погрешностям при расчете прогрева строительных конструкций. Предложен новый подход учета начальной температуры реальных пожаров математическими формулами, который позволяет повысить точность расчетов предела огнестойкости и огнесохранности строительных конструкций.
It is shown that the currently used approach to accounting for the initial temperature of the standard fire mathematical formulas leads to significant errors in the calculation of the warm building structures. A new approach taking into account the initial temperature of real fires mathematical formulas, which can improve the accuracy of calculations of fire resistance of building structures and ognesohrannosti.
