TECHNIQUE FOR CREATING THE PROTOTYPE OF A COMPACT FIRE PLANT FOR TESTS TO DETERMINE THE FIRE RESISTANCE OF REINFORCED CONCRETE STRUCTURES

Abstract

Reinforced concrete structures are widely used due to their well-known thermal resistance. Deterioration of their properties after exposure to fire includes loss of strength and modulus of elasticity, cracking and chipping of concrete. Also, the structural system of a building can be unexpectedly damaged due to the complexity of the structure and the property of durability. Therefore, it is important to study the thermal characteristics and structural behavior of damaged structures to understand their load-bearing capacity and safety. To solve the main tasks set in the work, the goal was set: to create a prototype of a small fire installation, to analyze the results of the experi- ment and the possibility of achieving a standard temperature of the fire. This paper describes the stages of creating a prototype fire installation, on the basis of the Training Complex of practical training of specialists of the Opera- tional and Rescue Service of Civil Protection of ChIFS named after Chornobyl Heroes of NUCD of Ukraine. The prototype of a small-sized fire installation was built on the basis of the analysis of the latest scientific achievements and publications [2-7] and taking into account all the significant shortcomings in the above-mentioned studies. During the fire tests, the temperature rise in the furnace chamber corresponded to the temperature rise when using the standard fire temperature curve
