Currently, in all building codes, the diagrams of dynamics coefficient are limited to a maximum natural oscillation period of 1.8 s. However, this range is clearly not enough for the calculation of constructions of high-rise structures with characteristic basic periods of about 4-5 s and more. This article analyzes the available seis-mological data presented in the Center for Engineering Strong Motion Data (CESMD) database. The spectra of Tolioku earthquakes (Tohoku earthquake. Japan. March 11. 2011) and Emberley (New Zealand Earthquake. New Zealand. November 13, 2016) were studied, and dynamic factors for periods of natural oscillations of structures 4-5 s are calculated. The results of the study allow to establish reasonable values of dynamic coefficients in the field of high periods.
