This paper presents the outcomes of experimental investigations into the application of newly developed seismic protection support components for enhancing the seismic safety of bridges and overpasses.Based on the results of experimental tests, the amplitude-frequency characteristics of traditional and new seismic protection components were compared, and the effectiveness of the new seismic protection component was substantiated. In addition, based on graphs, the diagrams of the installation of support parts for seismic protection of bridges, the AFCh of vibrations of a special unprotected support, the displacements of the span structure and the upper part of the support during seismic isolation of one span structure, the amplitude-frequency characteristics of the displacement of the span structure and the upper part of the support when the first span structure is combined with seismic protective and the second with movable and stationary support parts are compared.
