Review article

The issues of damping accounting in the linear-spectral theory of seismic resistance are considered in the article. Some shortcomings of the currently valid building codes related to the issue discussed in the study are outlined, and a comparison of available foreign approaches to accounting for damping other than the baseline one is provided. An approach is proposed that eliminates the need to introduce an additional factor to correct the dynamic coefficient relative to the base coefficient, and the correction of the dynamic coefficient is determined by the attenuation in the system and the stiffness of the structure. The dynamic coefficient was determined from the results of processing about 200 records of violent earthquakes. It is proposed to take into account the finiteness of the impact by introducing a correction factor when determining the dynamic coefficient.
