The seismicity of the construction area and construction sites is 9 points. To damp the movements arising during seismic impact, and uniformly distribute horizontal seismic load between all piers of the overcrossings and bridges, damping devices having elastic component, i.e., returning the superstructure to the initial position are installed in line of each pier between the superstructure beams and the stop node on the pier. In this regard, thoroughly movable ball and segment bearings are installed on all piers.
Watertight expansion joints of beam type of ‘Maurer Sohne GmbH&Co’ company compensate temperature movements on the intermediate piers and temperature and seismic movements on abutments. Shock transmitters, which are combining non-continuous superstructures into continuous ones in case of earthquake, are installed along with expansion joints.
