摘要：The structural reliability of the building ensures the building safety as a whole and the safety of the population, therefore the issue of ensuring reliability arises primarily in the design process. Buildings must be protected from destruction during all types of force, as well as in the case of load-bearing structures destruction as a result of emergency. Emergency impact on an object is an unregulated impact that is created as a result of an object getting into a special situation and can lead to its accident. The causes of structures progressive collapse are considered in this article. The main methods and methods of protecting buildings from progressive destruction are given. The calculation analysis of the monolithic reinforced concrete building frame for progressive collapse according to the method of possible damage is performed. There are many calculated and constructive proposals for solving the problems of counteracting the progressive destruction that can be divided into three categories: secondary protection measures, indirect design and direct design. In this article the resulting reinforcement of structural elements is determined taking into account the structural requirements for the continuity of longitudinal reinforcement, the minimum percentage of reinforcement. They are determined in the necessary places of additional reinforcement depending on the accepted permanent (background) reinforcement of the floors.
