Abstract
Ultra High Performance Fibre Reinforced Concrete (UHPFRC) presents one of the
superior classes of new cement base composites with the potential to achieve the
requirements for bridge constructions of the future. Not only the advantage of leading to
a high economy in construction contribute to this objective but the advantage of reaching
high service life and a reduction of maintenance will contribute as well. Nevertheless, only
few prototypes have been built up now by using this material.
This paper is aimed at highlighting the first stages of a case study where the use of a
structural health monitoring system to analyse actual structural performance of the Wild
bridge will lead to gain practical experience regarding structural performance of UHPFRC
road bridge constructions, to help in spreading the use of this profitable concept concrete
and to the standardisation bodies´ goal.
The designed Structural Health Monitoring (SHM) concept will be carried out by
using distributed fibre optic strain and temperature sensors, in combination with dynamic
non destructive measurements for obtaining periodically updated information and an
inverse FEM for developing actual performance life cycle models. To consider stress
distributions in the arch due to dead loads from the bridge deck, the monitoring starts from
the construction stage. The main goal is the analysis of the structural performance under
different life cycle operational environments. The long term objective is developing
performance based models for improving present UHPFRC design tools but also those
regarding optimised prognosis strategy for maintenance planning in the field of
transportation infrastructure.
