Functionally Graded Materials Pile Structure for Seismic Noise Cancellation
Publisher: ASCE
Abstract: This study explores surface-wave propagation through periodic arrangements of multilayered piles in a single-layer soil medium from the viewpoint of bandgaps. The influence of the geometrical parameters of the model on the ...
LIGO Newtonian Noise Cancellation Using Metamaterial-Based Periodic Structures
Publisher: American Society of Civil Engineers
Abstract: This paper presents a novel approach to mitigating Newtonian noise (NN) in laser interferometer gravitational wave observatory (LIGO) on Earth’s surface. The proposed method offers an unprecedented means to enhance the ...
Explainable XGBoost–SHAP Machine-Learning Model for Prediction of Ground Motion Duration in New Zealand
Publisher: ASCE
Abstract: Although ground motion duration significantly influences structural response, there is a lack of accurate prediction models for ground motion duration. Ground motion duration plays a vital role in structural response during ...
Focal Mechanism Influence with Azimuth Using Near-Field Simulated Ground Motion: Application to a Multispan Continuous Concrete Single-Frame Box-Girder Bridge
Publisher: ASCE
Abstract: Bridges in earthquake-prone states like California have been studied for near-field and far-field loadings. However, there is a research gap in terms of how an earthquake of a certain strike, dip, and rake is going to ...
