Software for thermal analysis of concretes at temperature heating
As a result of a fire, the collapse of structures is possible, both during extinguishing and subsequent operation of the building or structure. In addition, there are hidden high-temperature factors that affect building structures, they are dangerous because they lead to the impossibility of assessing the degree of damage to the object. Establishing the degree of damage to building structures, especially in the absence of obvious traces, is classified as particularly difficult. The paper proposes a comprehensive method for determining the foci of the greatest thermal damage in a fire (other temperature manifestation) and the degree of its impact on a concrete structure. A database has been collected and a program has been developed that allows, with the help of derivatographic analysis of concrete composites, to assess the degree of change in the physical and mechanical characteristics of structures. The results of using the software «Software for thermal analysis of concretes at temperature heating», developed on the software platform «NET Framework» with the use of the component for drawing graphs ZedGraph, are shown. The developed system is designed for the fastest and most efficient determination of the heating temperature of the test sample and the grade of concrete. The program will contain a database of commonly used concrete grades, such as B15, B22.5 and B25 at an ambient temperature of 20 °C and heated to 500 and 900°C, studied by synchronous thermal analysis.
