Abstrakt:

The city of Győr in western Hungary will be enriched with a significant transport investment of NIF PLC., a Hungarian infrastructure developer company. UNITEF’83 PLC. was commissioned with the design. The new road will cross the Mosoni-Danube over a spectacular new cable-stayed steel bridge. The future bridge is a 2-span, 68+144 meter-long box section structure, and its 65 meter-high inclined pylon will stand out from the city skyline. In addition to key design issues such as the global structural design and the details of the connections of the main load-bearing elements (cables), other structural problems requiring innovative solutions also arose during the design process. Several structural versions have been carefully analysed as early as in the initial phase of the design with the purpose of ensuring adequate torsional stiffness of the deck. Due to the sensitivity of the cable-stayed structure to the wind, cable vibration and the flow analysis of the beam and pylon also had to be carried out. The issue of construction technology had to be paid extra attention during the design procedure, since transportation by river and road were both limiting factors in the region. The paper covers the architectural and structural design of the future bridge in Győr, offering a brief outline of the most important details and solutions.
