REDEFINING THE LIMITS OF CONCRETE BRIDGE CONSTRUCTION WITH NON-METALLIC REINFORCEMENT

Zenodo (CERN European Organization for Nuclear Research)

Abstract

The pedestrian crossing on Ludwigsburger Straße in Stuttgart is a challenging curved concrete bridge combining a mix of FRP reinforcement types. Spanning 34 m over two spans, the bridge utilizes a circular ring girder concept. Stiffening ribs of only 15 cm depth, placed at 2.4 m intervals, support a thin 10 cm deck slab. The structure comprises precast elements in a semi-integral design. The paper highlights the design process, scientific investigations, and validation of the load-bearing capacity by means of a 1:1 test on one rib. It addresses the feasibility of using straight GFRP bars in frame corners and their interaction with other materials.
