A spectral pedestrian-based approach for modal identification (2019)
Journal Article
Jesus, A., Živanović, S., & Alani, A. (2020). A spectral pedestrian-based approach for modal identification. Journal of Sound and Vibration, 470, Article 115157. https://doi.org/10.1016/j.jsv.2019.115157

The dynamic behaviour of footbridges is characterised by modal properties such as natural frequencies, mode shapes, damping ratios and modal masses. Their estimation via modal tests often requires expensive or difficult-to-operate equipment (e.g. sha... Read More about A spectral pedestrian-based approach for modal identification.

Vibration-based Bayesian model updating of civil engineering structures applying Gaussian process metamodel (2019)
Journal Article

Modular Bayesian damage detection for complex civil infrastructure (2019)
Journal Article
Jesus, A., Brommer, P., Westgate, R., Koo, K., Brownjohn, J., & Laory, I. (2019). Modular Bayesian damage detection for complex civil infrastructure. Journal of Civil Structural Health Monitoring, 9(2), 201-215. https://doi.org/10.1007/s13349-018-00321-8

We address the problem of damage identification in complex civil infrastructure with an integrative modular Bayesian framework. The proposed approach uses multiple response Gaussian processes to build an informative yet computationally affordable pro...
