In KazNIISA JSC studies of seismic isolating properties of buildings equipped with special earthquake protection systems are carried out at the special field test site. Displacement, velocity and acceleration measuring sensors were installed on three houses constructed with the same above-foundation part (9-storey large-panel houses of series 158), but with different foundations: conventional strip foundations with the system of crossstrips, seismically isolating kinematic foundations and supports with PTFE gaskets. On these buildings instrumental records of the earthquake were received in the transverse direction on August 16, 2014. The resulting accelerograms were used to construct spectral curves ?. The possible effect of seismic isolation, as well as the influence of foundation constructions on the dynamics of buildings with foundations of conventional type and seismically isolated ones is assessed.
