The regulatory framework for earthquake-resistant construction in Russia has recently been supplemented by a number of new long-awaited documents. This seemingly positive phenomenon gave rise to a situation that in one article was not without reason called «normative chaos». This situation is largely due to the difference between the basic concepts and relations of new and familiar old normative documents, which generates a state in the mind, defined by psychologists as cognitive dissonance. Of course, this phenomenon is temporary and understandable, but for the case of examination and passage of working documentation, it is certainly harmful. This work aims, at least in part, to provide answers to questions.
The most important contradictions are briefly considered and reasoned answers to the questions are given. A complete analysis of the problems involved requires much more than the allowable size of the article.
