Local Scour Depth Prediction of Offshore Wind Power Monopile Foundation Based on GMDH Method

open access: yesJournal of Marine Science and Engineering, 2023
In recent years, Chinese offshore wind farms have experienced varying degrees of foundation scour since their completion. The maximum scour depth of pile foundations has far exceeded the design scour depth, which seriously threatens the safety of wind ...

Identification of Dynamic Parameters of Pedestrian Walking Model Based on a Coupled Pedestrian–Structure System

open access: yesApplied Sciences, 2021
As human occupancy has an enormous effect on the dynamics of light, flexible, large-span, low-damping structures, which are sensitive to human-induced vibrations, it is essential to investigate the effects of pedestrian–structure interaction.

Nonlinear Behaviour of Concrete Buttress Dams under High-Frequency Excitations Taking into Account Topographical Amplifications

open access: yesShock and Vibration, 2021
Concrete buttress dams could potentially be susceptible to high-frequency vibrations, especially in the cross-stream direction, due to their slender design.

Monitoring and testing corrosion and responsive behaviour in galvanic systems. [PDF]

open access: yesMATEC Web of Conferences, 2019
Testing methods for corrosion prevention in structures have, historically, been based on the steel polarising from the protective current. Modern galvanic systems aim to protect the steel by restoring the protective alkaline environment, rather than ...
