Measurement of bridge dynamic displacements and natural frequencies by RTS

Ante Marendić, Rinaldo Paar, Domagoj Damjanović

Abstract

The use of RTS for measuring displacements at the Sava railway bridge during load testing after bridge rehabilitation is presented in the paper, and a special emphasis is placed on the determination of displacements when the bridge was subjected to dynamic load and natural frequencies. Measurement results are compared to numerical analysis results and to natural frequency results obtained by the Operational Modal Analysis (OMA).

Keywords
RTS, dynamic displacements, load testing, natural frequencies of the bridge, OMA
