English abstract:
Ultra High Performance Fibre Reinforced Concrete (UHPFRC) presents one of the superior classes
of new cement base composites with the potential to archive the requirements for bridge
constructions of the future. Not only the advantage of leading to a high economy in condition
contribute to the 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 to highlight the use of structural health monitoring system to analyse the
structural performance of the UHPFRC Wild Bridge during construction. This leads to gain
practical experience regarding the performance of UHPFRC structures, and to help in spreading the
use of this profitable concept concrete and to the standardisation.
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 the 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.
