Kazimierz-Ludwinów footbridge over the Vistula River in Cracow

摘要

The paper presents the technical design of an innovative structure of Kazimierz-Ludwinówrnfootbridge in Cracow over the Vistula River. The main span of the footbridge represents veryrnunusual structural form. Static system of its two of three decks can be defined between a fixed beamrnand a shallow arch. The third deck supported by the two main decks has a sinusoidal profile. Thernmost complex elements of the structure designed with rigorous requirements of architecturalrnforming are indicated. These extraordinary elements are: massive concrete supports with arncomplicated geometric shape, steel decks of the main span composed of irregular tapered boxrngirders prestressed in the edge parts of the spans and the whole structure of the approach ramps.rnSome details of numerical modelling of the structure by means of FEM are presented as well as thernconcept of the footbridge construction technology is discussed.
