CREATION OF AN EXPERIMENTAL TEST BENCH IN THE FRAMEWORK OF FIRE SPREAD LIMITATIONS RESEARCHED THE BUILDER ON THE FACADES

Abstract

Based on the results of analytical studies of the existing assessment methods for ensuring the limitation of the spread of fire on the facades of buildings, shortcomings were identified that can significantly affect the accuracy of their fire safety assessment. The justification is provided and the main design characteristics that the new experimental stand must comply with are given, taking into account the previously identified shortcomings of the existing methods for assessing the effectiveness of the spread of fire on the facades of buildings. The stages of creation of experimental test equipment are presented and the requirements for the physical and mechanical properties of the materials from which the main structural elements of the test bench are made are substantiated. Verification of the declared technical characteristics of the test bench was carried out and its potential capabilities of reproducing real fragments of facade systems were given. The main parameters and procedures of the method of research and assessment of the spread of fire on the facades of buildings, which are planned to be implemented within the framework of the use of a new experimental stand, are described. Prospective directions of research regarding the improvement of the experimental test bench to ensure a more accurate assessment of the effectiveness of limiting the spread of fire on the facades of buildings with the help of fire barriers are given.
