The behavior of the 25-storey building of “Kazakhstan” hotel during the earthquake on March 26, 2018 is analyzed. The focus of the earthquake was
near the town of Kapshagai. A digital station of the engineering and seismometric service installed on the hotel building. Absence of resonance phenomena of the building at the specified earthquake was revealed. Acceleration distribution curves have been constructed at building levels on the azimuth plane. Significant acceleration in the vertical direction in the level of the technical floor is noted, which can be caused by a previously unidentified tectonic fault near the building. It has been established that in the basement level the maximum period of the spectrum is about 0.18 seconds. For the first time, the energy characteristics of instrumental records in the building levels have been determined.
Keywords: accelerogram, seismic station, accelerations, period of oscillations.
