Probabilistic examination of the change in eigenfrequencies of an offshore wind turbine under progressive scour incorporating soil spatial variability (2017)
Journal Article
Prendergast, L., Reale, C., & Gavin, K. (2018). Probabilistic examination of the change in eigenfrequencies of an offshore wind turbine under progressive scour incorporating soil spatial variability. Marine Structures, 57, (87-104). doi:10.1016/j.marstruc.2017.09.009. ISSN 0951-8339

The trend for development in the offshore wind sector is towards larger turbines in deeper water. This results in higher wind and wave loads on these dynamically sensitive structures. Monopiles are the preferred foundation solution for offshore wind...

Isolating the location of scour-induced stiffness loss in bridges using local modal behaviour (2017)
Journal Article
Prendergast, L. J., Gavin, K., & Hester, D. (2017). Isolating the location of scour-induced stiffness loss in bridges using local modal behaviour. Journal of Civil Structural Health Monitoring, 7(4), 483-503. https://doi.org/10.1007/s13349-017-0238-3

Detecting scour by analysing bridge vibrations is receiving an increasing amount of attention in the literature. Others have considered changes in natural frequency to indicate the presence of scour damage; however, little work has been reported on i...

Retrofit Design Methodology for Substandard R.C. Buildings with Torsional Sensitivity (2017)
Journal Article
Thermou, G. E., & Psaltakis, M. (2018). Retrofit Design Methodology for Substandard R.C. Buildings with Torsional Sensitivity. Journal of Earthquake Engineering, 22(7), 1233-1258. doi:10.1080/13632469.2016.1277569

Recent earthquakes have revealed the susceptibility of non-ductile reinforced concrete (R.C.) buildings with deficiencies related to stiffness and/or mass irregularities in plan and elevation. This paper proposes a design methodology for the seismic... Read More about Retrofit Design Methodology for Substandard R.C. Buildings with Torsional Sensitivity.
