Output-only modal testing and monitoring of civil engineering structures: instrumentation and test management

Nguyen, A. and Chan, T. H. T. and Thambiratnam, D. P. and Kodikara, K. T. L. and Le, N. T. and Jamali, S. (2018) Output-only modal testing and monitoring of civil engineering structures: instrumentation and test management. In: 8th International Conference on Structural Health Monitoring of Intelligent Infrastructure (SHMII 2017): Structural Health Monitoring in Real-World Application, 5-8 Dec 2017, Brisbane, Australia.


Development of output-only modal testing and monitoring systems of real civil engineering structures albeit very appealing have been very challenging to engineers of any progression. This paper analyses some of the most critical issues that are needed for the success of implementing this approach to civil engineering structures. Illustrations are made based mainly on the applications developed by the present authors when conducting their research at the Queensland University of Technology (QUT). For illustration purposes, two representative test structures are selected to reflect different characteristics of structures. This paper then focuses in detail on instrumentation aspects since these are amongst the most confusing issues. All necessary components of complete instrumentation systems are analysed with different scenarios and structures. Last shared are some key notes on the test management process which is especially relevant to long-term modal-based monitoring applications.
