UHPFRC Segmental Footbridge Velodrom in Brno

<p>The new crossing of 7 road lines is designed as a single-span parapet beam with overhanged parts. The superstructure is composed of 7 UHPFRC segments that are prestressed by unbonded strands. This approach was adopted because of the footbridge’s temporary life in this place. UHPFRC segmental footbridge was selected because it allows a dismantling of the superstructure and its reassemble in different segmental layouts elsewhere. The main span is 53.8 m with an overhang is 2.55 m at each side. The cross section in the main span is ‘U shape’ with a recessed wall, the total height is 1.475 m. Overhang parts are “L shape” segments and they are connected to U shape by a combination of prestressing bars and tendons.</p>
