COMPUTATIONAL ANALYSIS OF THE THERMAL STATE OF METAL LOAD-CARRYING STRUCTURES OF A STADIUM FOR VARIOUS FIRE SCENARIOS

摘要

This paper considers a numerical model and a method of its construction and verification, as well as the results of calculations of the distribution of nonstationary temperatures of structures with the example of analysis of the thermal state of complex load-carrying metal elements of awnings over the stands of the "Olimpiiskii" stadium (Kiev) under the conditions of three scenarios of possible fires. We have estimated the fire-resistance of these structures using the field method (CFD technology) realized with the aid of ANSYS FLUENT and FDS computer programs.
