Arched Reinforced Concrete Pylon Composite Bridge in Hungary

In this paper the design and the construction of a unique bridge are presented, and the history of the basic idea is described as well. The bridge spanning over the second largest river is innovative in many ways in Hungary, such as the first bridge with non-prestressed reinforced concrete pylons (allowing tension), the first cable-stayed bridge applying saddles, the first cable bridge with composite stiffening girder, etc. These facts and the immaturity of the antecedent designs repeatedly raised problems to which unique answers had to be found in the detailed design phase.

To bring them into their exact final position, the erection control of the pylon and the composite stiffening girder had to be designed and carried out, which required extremely precise calculation and construction. The building of the half ellipse pylon, which also proved a serious challenge to the contractors is also discussed.
