What is it about?
The causes of failures are considered, the consequence of which can be considered progressive collapses of structures and consideration of structural safety in more expanded representations than when assessing the first and second groups of limit conditions for low-rise buildings constructed from local materials

Why is it important?
Buildings and structures are designed so that certain operating parameters are provided. However, the actual situation does not make it possible to guarantee full compliance of the constructed object with the projected characteristics. It is clear that nothing can be said in advance about the degree of violation of such compliance, however, to a certain extent it is possible to provide for the sensitivity of the structure to defects, both initial state and accumulated during operation. Therefore, it is necessary to introduce a third group of limiting states - for survivability and structural safety of buildings and structures.
Perspectives
The approach under consideration for modeling irreversible processes accompanying the operation of structures is synergetic, then decisive importance is attached to the process of controlling this parameter. It is quite obvious that the imperfection parameter β can be considered a probabilistic characteristic. According to the results of this study, it is clear that the initial value of the imperfection parameter β_* corresponds to the initial parameter of the order n_*. During the transition of the material to the transcendental region, a change in the type of stability is accompanied by strong structural fluctuations.Therefore, the appearance on the graph of the inflection point corresponding to the ultimate strength of the material is quite predictable.
