TWIN STAYED GIRDERS TO CARRY ECCENTRICALLY PLACED RAILROAD

As part of a 33-km (20-mile) crossing of the twin channels of the Parana River in Argentina, a pair of 1082-m main-span steel-stayed bridges have been erected to carry the four-lane roadway with a single-track railroad at one side which produces unusual dynamic, torsional and asymmetrical loadings. The original concept of through trusses was abandoned in favor of placing the track on top of the trusses. To cope with asymmetrical loads, there are double the number of cables on the rail side and special horizontal torsional bracing. Problems of design, financing and construction are described.
