NONLINER ANALYSIS OF TROJA BRIDGE IN PRAGUE

Jan Červenka, Jan L. Vítek, Vladimír Červenka

Summary

Nonlinear analysis was used to verify the extent of cracking and crack widths in the end segment of Troja bridge in Prague. The bridge has a main span of 200.4 m, and it is a simply supported bowstring-arch type bridge with two longitudinal pre-stressed steel-concrete chords.  The deck slab is 36 m wide, and is composed of prefabricated cross-beams with cast in place concrete deck, which is pre-stressed in both longitudinal and transverse directions. The paper presents results from a nonlinear analysis, which consisted of the 3D model of 1/4 of the bridge including all concrete, steel elements as well as the cables. The analysis simulated the whole construction process, and its main objective was to verify the cracking in the massive concrete slabs above the supports at the bridge ends. The nonlinear analysis proved that the cracking would not be extensive, and the crack widths would remain in acceptable limits. This enabled the elimination of additional very short pre-stressing cables in these segments, which reduced the bridge cost as well as simplified the construction process.
