    Abstract. The article contains some general recommendations for the design and operation of buildings and structures subjected to dynamic impacts. Requirements for levels and nature of vibrations, which are established depending on the reaction of people, conditions of normal operation of technical equipment, general building response (integrated assessment), possible development of undamped settlements are presented. The main stages which should be included in the general program for determining vibration levels and their analysis depending on the position of the source, within the structure (internal sources) and outside of the structure, are noted. Two examples of obvious errors, made when designing buildings, which are related to dynamic impacts are given. At mineral processing factories, where mechanical screens were installed, the closeness of the frequencies of own vibrations of neighboring spans and the excitation frequencies was not taken into account. Resonant vibrations, the levels of which exceeded the normalized SN 2.24/ "Industrial vibration, vibration in residential and public buildings" by an order of magnitude, were initiated. Other cases are associated with the development of significant settlements of buildings (up to 20-50 cm) due to the use of the vibro-active equipment: forging and stamping hammers. In these cases, the requirements of SP 26.13330.2012 were met. However, the levels of acceleration of oscillation far exceeded the levels recommended in technical literature (more than 40 cm/s2).
    Key words: dynamic and vibration impacts, design of buildings and structures, settlements of buildings, vibration level, normalization.
