System Identification with Coda Waves at the Gänstorbrücke in Ulm

The Gänstorbridge in Ulm is crossing the Danube with a maximum span of 82,40 m. Among others is the bridge instrumented with 20 ultrasound transducers for structural health monitoring. These special types of ultrasound waves allow for the monitoring of concrete structures with diffuse ultrasound (coda waves).

Direct imaging of the coda of teleseismic P waves

2005
This paper reviews the theoretical background of existing techniques for direct imaging of the coda of teleseismic P waves. A unifying theme of all approaches is the Born series for elastic wave scattering. Inversion methods for one-dimensional structure commonly included multiply scattered waves while all existing two and three-dimensional ...

Impact of Microstructural Changes in Concrete on Coda Waves

Coda wave interferometry (CWI) is a novel non-destructive method for monitoring concrete structures. It is sensitive to material changes and can serve as an early warning system for damage. CWI compares two ultrasonic waveforms to detect velocity changes, especially in heterogeneous media.
