On August 9, 2017, a strong earthquake with a magnitude Mw = 6.3 occurred in the Xinjiang Uygur Autonomous Region of China. For the first time in the last 10 years, representative instrumental data were obtained at the seismic station No. 11 (“Prospect Abay”) in the city of Almaty, equipped with a digital instrumentation and measuring system. The building is eleven-story and is made in a steel frame. In the city of Almaty, there is a significant number of residential and public buildings made in a steel frame. Using the AT 1105 sensors and the RSM-8 recorder, high-quality instrumental records of accelerations in the basement and on the roof of the building were obtained, as well as the β spectral curves. The frequency composition of the impact at the basement level has been determined. The prevailing period of fluctuation at the basement level is 0.3 sec, and at the roof level is close to 1.3 sec. It was found that during a remote earthquake, resonant vibrations of the building took place. The results of the work can be used in the design of buildings with a steel frame in the city of Almaty.

“…The proposed method for calculating seismically isolated systems can be used to study any kinematic type systems, for example, on rubber blocks [6,14,15]. -When providing movement at the KF level of the order of up to 10-12 cm, the building should be recognized as seismic resistant at the median values of acceleration at the base of the "Map of seismic zoning of the Republic of Kazakhstan" for Almaty.…”

“…A fairly simple and effective means of reducing the risk of losses in case of possible earthquakes are seismic isolation systems of various types, which have been intensively developing over the past 30 years [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Several thousand seismically isolated objects have already been built in the world.…”

To study the seismic properties of buildings in Almaty, a special test site operates. It includes buildings with conventional strip foundations with a system of cross belts and seismic support of 2 types. The landfill buildings were previously tested under static and dynamic influences. With the use of real accelerograms of earthquakes, a forecast of the behavior of a seismically isolated house on kinematic foundations under seismic influences has been carried out. The seismic impact is represented by a set of real accelerograms of strong, mainly Californian earthquakes. The hearts depths and magnitudes correspond to possible Almaty earthquakes. Two design schemes of a seismically isolated building are considered - single-mass and 10-mass dynamic building models. It is shown that the magnitudes of displacements in the kinematic foundations (KF) level obtained by two dynamic models usually differ within 5-10%. Therefore, the calculation of seismically isolated buildings can be applied to a single-mass non-linear dynamic model. A linear regression connection was obtained between the values of acceleration at the base and displacements at the level of the foundation. For the values of acceleration according to the new "Map of seismic zoning of the Republic of Kazakhstan" were obtained the predicted values of displacement at the level of the kinematic support of the order of 8.0-11.5 cm.
