In recent years, in the Republic, the design and construction of continuous reinforced concrete bridges and overpasses were conducted at a colossal pace. Foreign advanced technologies, methods, and software systems were taken into account. Foreign experience in studying rubber-metal bearing parts of bridges and overpasses was analyzed. The article presents the calculation of a continuous reinforced concrete overpass for seismic impacts using the finite element method in the framework of the linear spectral theory. Numerical calculations have shown that the bearing part of the right end of the overpass does not allow the span to fall from the abutment because the maximum displacement of the rubber-metal bearing part is 0.2 m. As a result, the span structure and overpass supports have an overestimated margin of safety for an 8-point earthquake, according to MSK-64.
Key words: bridges and overpasses / seismic isolation / support parts / span structure / pier / compression and tension / monolithic structures
