Project DescriptionFROM THE AMERICAN CONCRETE INSTITUTE:
The footbridge in Celakovice is connecting the town on the left bank of the Labe River with a popular recreational area on the right bank. It enables comfortable river crossing for pedestrians, cyclists and emergency vehicles up to the weight of 3.5 t. The contractor implemented an alternative proposal of a segmental bridge deck made entirely of UHPC concrete C130/150 with steel fibre reinforcement instead of the composite deck. The depth of the deck slab is 60 mm only, no bar reinforcement is used. The arrangement of spans is 43+156+43 m. Steel pylons of a total height of 37 m are fixed on the foundation blocks on bored piles. Stays are arranged in two planes, the lower adjustable anchorages are located on the side of the deck. The deck is supported by fully locked cable-stays. The footbridge over the Labe River in Čelakovice is the first structure in the Czech Republic which has a superstructure made of UHPC. The design and the execution of the footbridge were based on experimental experience with the new material. The design is at some parts conservative due to the limited knowledge on the performance of the UHPC. Very fast assembling - one month only - of the main span above the river was achieved.
