Method of engineering calculation of the fire resistance limit for load-bearing metal structures
Annotation
The results of the calculation for heating of load-bearing metal structures under conditions of high-temperature exposure are considered and discussed. The reliability of the obtained results of heat engineering calculations determines the accuracy and reliability of the assessment fo fire resistance of building structures. To assess the fire resistance of load-bearing structures, a numerical calculation of the temperature fields for metal structural elements with the functionality of the developed software package is proposed. The software package allows you to automate the calculation of the actual fire resistance limit for both unprotected and fire-protected metal elements of building structures in time, taking into account variable high-temperature influences.
