ABSTRACT
An interesting local seismic event was registered on the Almaty territory. In terms of intensity, this is a two-point earthquake. The earthquake was recorded only by the stations of the engineering and seismometric service of KazRDICA JSC on October 18, 2017. The station is located in a 4-story frame building. Ground conditions – boulders and pebbles. Using AT 1105 sensors and an RSM-8 recorder, station No. 1 “Institute” recorded instrumental records of accelerations in the basement and on the building roof and plotted the spectral curves β. Period 0.43 sec corresponds to the value of the free oscillation period. It was revealed that even with a low-intensity local seismic impact, the dynamic characteristics of the building are exposed. The active operation of the building as a whole corresponds to the classical Biot spectral theory. The periods of oscillation of the building and soil of the base are quite accurately determined.
