Abstract EN
The aim of this paper is to apply both time- and frequency-domain-based approaches on real-life civil engineering structures and to assess their capability for damage detection.
The methodology is based on Principal Component Analysis of the Hankel matrix built from output-only measurements and of Frequency Response Functions.
Damage detection is performed using the concept of subspace angles between a current (possibly damaged state) and a reference (undamaged) state.
The first structure is the Champangshiehl Bridge located in Luxembourg.
Several damage levels were intentionally created by cutting a growing number of prestressed tendons and vibration data were acquired by the University of Luxembourg for each damaged state.
The second example consists in reinforced and prestressed concrete panels.
Successive damages were introduced in the panels by loading heavy weights and by cutting steel wires.
The illustrations show different consequences in damage identification by the considered techniques.
