About the Safety of Mass Residential and Public Buildings in Case of Dangerous Natural Influences

The obligation for the construction system of Russia to prevent human casualties in construction projects under the influence of hazardous natural phenomena is clearly indicated in paragraph 1 of Article 1 of Federal Law No. 384-FZ “Technical regulations on the safety of buildings and structures», where it is clearly stated that « this Federal law is adopted in order to protect the life and health of citizens, the property of individuals or legal entities, state or municipal property...». However, the regulatory level of risk in GOST 31937–2011 «Buildings and structures. Rules for inspection and monitoring of technical condition» allows human casualties in mass residential and public buildings when exposed to dangerous natural phenomena. It is known that when calculating mass residential and public buildings only for the minimum normative values of dangerous impacts, human casualties cannot be avoided. Specialists know that the main characteristic of all natural hazards on Earth (earthquakes, floods, etc.) is cyclical in their manifestation (significant declines are necessarily replaced by significant increases). That is why, for example, settlements as the largest capital construction projects in Russia with a service life of one thousand years or more should be calculated only for the maximum impacts of natural hazards. However, the standard set of seismic maps OSR-2015 for certain regions of Russia shows only the average (underestimated) values of such essential characteristics of earthquakes as intensity and repeatability.
