Analysis of railway vehicle-track interaction performance in submerged floating tunnel subjected to wave excitations
Song, Yang; Dai, Jian; Lau Leong Lee, Albert (Journal article; Peer reviewed, 2024)Submerged Floating Tunnels (SFTs) are an innovative and appealing solution for the water crossing of railways over wide and deep waterbodies where it is challenging or even impractical to construct conventional bottom-founded ... -
Evaluation of Frequency Content of Accelerations Recorded on Trains Crossing Multi-span Bridges
Erduran, Emrah; Gonen, Semih; Pettersen, Fredrik Marøy; Lau Leong Lee, Albert (Chapter, 2023)The literature on drive-by methods that aim to estimate the dynamic properties of bridges from the acceleration response recorded on the vehicle is generally limited to highway bridges, with few studies focusing on railway ... -
Identification of Vibration Frequencies of Railway Bridges from Train-Mounted Sensors Using Wavelet Transformation
Gonen, Semih; Lau Leong Lee, Albert; Pettersen, Fredrik (Peer reviewed; Journal article, 2023)This article presents a novel methodology to extract the bridge frequencies from the vibrations recorded on train-mounted sensors. Continuous wavelet transform is used to distinguish the bridge frequencies from the other ...
