| Summary: | The work is devoted to the principle of designing residential quarters with the exclusion of building collapse according to the “domino” principle, ie. without the development of progressive collapse in the event of an accident. This principle increases the efficiency of the “green” development of the construction industry. The work provides real examples when the mistake of the architect of the improvement of the district cost the integrity of a large quarter, presents pictures of man-made disasters associated with the collapse of entire microdistricts. The text of the article is a study of methods and tools for designing buildings and structures, which, being combined into one quarter, will be able to maintain structural integrity in the event of a collapse of one of the components of such a residential building. The principles of calculating a reinforced concrete monolith that prevent progressive collapse are highlighted. Also, the text of the article contains the author’s nomogram, obtained empirically and confirmed by experiments.
