Abstract To reduce the effect of dynamic traffic and seismic loads, it is proposed to use a seismic insulating support, the contact surfaces of which are pasted over with a fluoroplastic film. The dry friction coefficient for a fluoroplastic pair is 0.03-0.05. Due to the small value of the dry friction force, the support will operate both during traffic and seismic effects. Instrumental records of accelerations recorded by the devices of the ESS station No. 22, installed on a nine-story single-section large-panel building of series 158 in the city of Almaty, are analyzed. The earthquake source is 148 km from the city of Almaty. The house is equipped with a seismic isolation system. The foundations of the building are sliding supports. The values of acceleration along the height of the building are analyzed, and the spectral curves β are also constructed. The presence of 2 maxima on the spectral curves β at periods of 0.13-0.14 sec and 0.44-0.47 sec is revealed. The absence of resonance phenomena under the combined action of seismic and traffic loads is shown. The seismic support is proposed to be used on dense soils. Thus, transport and seismic loads can be effectively reduced.
