The relevance of the study is due to the lack of land for Almaty city development. The study purpose is to study the behavior specifics of a 35-story residential building in Almaty city under seismic loads according to calculations during its design. To study the set task, an experimental study of the dynamic load was carried out using a B-3-type vibration machine. Thus, the paper considers the results of dynamic tests of a 35-story building with a frame-wall construction. Dynamic tests were carried out using a vibration machine with an inertial effect installed on the building floor. Vibration recording was carried out using a digital instrument-measuring system. In the course of the study, insignificant differences were revealed in the calculated and experimental values of the vibration periods. When determining the design seismic loads on facilities of such type, the values of logarithmic vibration decrements are recommended to be taken within 0.12-0.18 (ξ=2-3%). Among the conclusions, the need to amend regulatory documents in construction, as well as the following observation of the high-rise were identified.
