STAGES OF CREATING A PROTOTYPE OF A FIRE INSTALLATION FOR DETERMINATION OF TEMPERATURE DISTRIBUTIONS OF SMALL FIGURES OF REINFORCED CONCRETE STRUCTURES

Abstract

Building structures play an important role in ensuring fire protection of buildings, so the determination of fire resistance of building structures is a topical issue. There are errors in both experimental and calculation methods for determining fire resistance, respectively, the improvement of methods and tools is an appropriate issue. According to the results of this work, the following was established: the purpose of the work was to create a prototype of a small fire installation and analyze the results of test launches, including temperature distributions in the fire furnace chamber and the possibility of achieving a "standard" fire temperature mode.

We considered and analyzed literature sources in which the basic requirements of methods of tests on fire resistance of building constructions are specified and on the basis of which the prototype of the compact fire installation for research of fire resistance of vertical bearing building constructions was created. The method of conducting an experimental study to determine the fire resistance of vertical load-bearing building structures is revealed. The distribution of temperatures over the entire area of the fire furnace was checked and the obtained results were analyzed. The created prototype of the fire furnace gives the chance to define experimentally fire resistance of vertical bearing building designs..

After analyzing the results of the experiment, it became possible to claim that this method of testing building structures for fire resistance allows to reproduce the standard temperature in the furnace chamber.
