Concrete bridge, Czech Republic
The bridge is located at the second most important crossroad of the city ring road section. It is a single span bridge structure with a span of 43.5 m made of post-tensioned prestressed concrete. The width of the bridge varies from 78.3 m in the middle to 89.6 m at the end of the bridge. The total area of the bridge is 3800 m2.
During the design, it was determined whether this structure can be realized as a frame bridge. This type of construction was very economically inefficient and technically demanding. It was necessary to anchor the substructure, use connectors to bind reinforcement in the corners, prestress the retaining walls and frame corners, etc. Through successive calculations, we came to the final variant of semi-integral bridge on deck foundations.
