Structure Health Monitoring using Vibration-based Technique

Vibration-based Health Monitoring of Highway Bridge Structures Using Output Only Modal Parameter Estimation Technique

This paper discusses the implementation of a Structural Health Monitoring system for a FRP bridge structure using vibration-based monitoring techniques. The need to monitor the long-term performance of fiber reinforced polymer (FRP) composite bridge structures prompted the installation of a vibration-based structural health monitoring system on a recently-built FRP composite highway bridge in C...

Vibration-based Structural Health Monitoring Technique Using Statistical Features from Strain Measurements

A statistical vibration-based damage identification algorithm to assess the stability of the measurement data, detect and locate damage in civil structures, where variability in response and modal parameters due to measurement noise and environmental influence is often inevitable, is presented in this paper. The method exploits the regression analysis of peak values of the magnitudes of frequen...

Implementation of an Operational Modal Analysis Technique for Vibration - Based Structural Health Monitoring by Alejandro

Vibration-based structural health monitoring (SHM) has become an attractive solution for the global monitoring and evaluation of damage in structures. Numerous damage detection schemes used in vibration-based SHM require knowledge of the modal properties of the structure under evaluation in its current state. The technique of operational modal analysis allows for these modal properties to be ob...

Vibration based Structural Health Monitoring of a Composite Plate Structure with Multiple Stiffeners

A vibration based damage identification method is investigated experimentally. The dynamic response of an intact and a locally damaged 16–layer unidirectional carbon fibre PEKK reinforced plate structure with two stiffener sections is considered. A forced–vibration set–up, including a laser vibrometer system, is employed to measure the dynamic behaviour. The feasibility of the two–dimensional M...
