Wunsch Construction.--The flat-topped arch construction of reinforced concrete designed by Robert Wiinsch of Budapest, Hungary, in 1891, has been employed in building several notable structures in the country of its origin. The Wunsch reinforcement consists of a horizontal top member of T section placed with its flange upward and of a curved intradosal member of the same section placed with its flange downward. At the crown of the arch the webs of the two members overlap and are riveted together, and at the ends of the arch a vertical tie connects the two members and extends downward into the pier or abutment masonry, where it is anchored to a girder extending along the pier transversely of the bridge. These frames, constructed as described, are placed parallel to each other longitudinally of the arch and from 18 ins. to 2 ft. apart. The ratio of the crosssections of the reinforcement and of the concrete at the crown of the arch is generally about 2 to 1oo. The concrete embedding the curved member of the frame is much richer than that at the top of the arch which embeds the horizontal member. To illustrate Wiinsch construction as applied to bridges, the Emperor Bridge at Sarajevo, Bosnia, and the Maryborough Bridge, Queensland, have been selected. Emperor Bridge, Sarajevo, Bosnia.--The Emperor Bridge at Sarajevo, Bosnia, crosses the river Miljacka, with a clear span of 25.36 m. (115.8 ft.) and with a rise of one-tenth the span.
