Journal Article
Tott-Buswell, J., Garala, T., Prendergast, L., Madabhushi, S., & Rovithis, E. (2022). Seismic response of piles in layered soils: Performance of pseudostatic Winkler models against centrifuge data. Soil Dynamics and Earthquake Engineering, 153, Article 107110. https://doi.org/10.1016/j.soildyn.2021.107110

In this study, the suitability of the pseudostatic approach for the seismic analysis of pile foundations in layered soils is explored by means of experimental data from centrifuge tests performed at 60g. A free-head single pile and a capped (1 × 3) p... Read More about Seismic response of piles in layered soils: Performance of pseudostatic Winkler models against centrifuge data.

Experimental and numerical investigation of the effect of vertical loading on the lateral behaviour of monopiles in sand (2021)
Journal Article
Li, Q., Gavin, K., Askarinejad, A., & Prendergast, L. (2022). Experimental and numerical investigation of the effect of vertical loading on the lateral behaviour of monopiles in sand. Canadian Geotechnical Journal, 59(5), 652-666. https://doi.org/10.1139/cgj-2020-0769

The influence of combined loading on the response of monopiles used to support offshore wind turbines (OWTs) is investigated in this paper. In current practice, resistance of monopiles to vertical and lateral loading is considered separately. As OWT...

Impact of Geotechnical Uncertainty on the Preliminary Design of Monopiles Supporting Offshore Wind Turbines (2021)
Journal Article
Reale, C., Tott-Buswell, J., & Prendergast, L. J. (2021). Impact of Geotechnical Uncertainty on the Preliminary Design of Monopiles Supporting Offshore Wind Turbines. ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part B: Mechanical Engineering, 7(4), Article 040903. https://doi.org/10.1115/1.4051418

The growing demand for clean renewable energy sources and the lack of suitable nearshore sites are moving the offshore wind industry toward developing larger wind turbines in deeper water locations further offshore. This is adding significant uncerta... Read More about Impact of Geotechnical Uncertainty on the Preliminary Design of Monopiles Supporting Offshore Wind Turbines.

Wavelet-based operating deflection shapes for locating scour-related stiffness losses in multi-span bridges (2021)
Journal Article
OBrien, E. J., McCrum, D. P., Khan, M. A., & Prendergast, L. J. (2023). Wavelet-based operating deflection shapes for locating scour-related stiffness losses in multi-span bridges. Structure and Infrastructure Engineering, 19(2), 238-253. https://doi.org/10.1080/15732479.2021.1937235

Scour erosion poses a significant risk to bridge safety worldwide and affects the stiffness of the soil-foundation system, resulting in global changes in the dynamic behavior of the bridges. In this paper, a new approach to detect scour at multiple l... Read More about Wavelet-based operating deflection shapes for locating scour-related stiffness losses in multi-span bridges.

Laboratory investigation of a bridge scour monitoring method using decentralized modal analysis (2021)
Journal Article

Scour is a significant issue for bridges worldwide that influences the global stiffness of bridge structures and hence alters the dynamic behaviour of these systems. For the first time, this article presents a new approach to detect bridge scour at s... Read More about Laboratory investigation of a bridge scour monitoring method using decentralized modal analysis.
