Many regions of the Russian Federation are located in seismic areas. Therefore, one of the most important issues of ensuring the mechanical safety of buildings and structures being built in seismically active areas is its seismic resistance. Special methods of seismic protection are becoming more widespread, the use of which allows you to adjust the dynamic response of buildings during seismic impact. In this paper, an approach is considered to ensure seismic protection of the terminal building in the city of Yelizovo in the form of a hydraulic damper.

Research methods: constructive solutions of the building were analyzed in terms of ensuring the seismic resistance of the building. A comparative analysis of the calculations of the building for seismic impact with and without seismic protection elements was carried out. The calculation for the seismic effect was carried out in the time domain using direct integration of the equation of motion, while the damper operation was modeled by an element with hysteresis work. The analysis of the efficiency of seismic protection was carried out.

Results: The results of scientific and technical support are presented within the framework of which the calculations of the spatial model of the terminal building in the city of Yelizovo were carried out for seismic impact with an estimated intensity of 9 points on the SSI-2017 scale [3]. The method of seismic protection in the form of devices regulating the dynamic response of the building (hydraulic damper) is considered. The selection of a seismic protection system was performed and the decrease in accelerations and forces in the main load-bearing structural elements under seismic action was shown.
