The results of reference building (analogous building) research at the seismic isolation site is presented in the study. A system of cross-strips foundations, seismic insulating kinematic foundations and pillars with fluoroplastic gaskets were utilized in building construction. There are stations of engineering seismological measurement services installed on the buildings. It is analyzed the experimental studies for analogous building performed in the late 80s. The results are compared with the earthquake instrumental records happened on August 16, 2014. According to the seismological measurement services the building oscillation period is 0.40 sec, that fully corresponds to data vibration test with a minimum load of unbalances - 0.39-0.42 sec. It has been established that the floor distortions decrease with building height. Mainly the building is deformed by shear scheme. Taking into account the experimental data, a piecewise linear diagram of the deformation of a single-mass dynamic model of a building is constructed.
