Near field enhancements from angled surface defects : a comparison of scanning laser source and scanning laser detection techniques [PDF]
, 2011 Enhancement of the Rayleigh wave signal amplitude at a surface defect, due to interference of incident, reflected and mode converted waves, has been reported by several authors, and it has been suggested that this could be used as a fingerprint of the ...

Development and Validation of a Seismic Design Method for Anchored Retaining Walls
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Retaining walls with multiple anchor levels are widely used as permanent excavation support systems for the construction of linear infrastructures. Yet, their seismic behaviour remains largely unexplored, and current design approaches rely on conventional procedures that do not adequately reflect the actual dynamic response of these systems ...

Displacement Estimation of Structures With Flag‐Shaped Hysteresis Loops
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Time‐history analyses were conducted on single‐degree‐of‐freedom (SDOF) systems with flag‐shaped hysteresis loops using a far‐field ground motion suite to estimate peak displacements, Δp, and equivalent deformation cycles, Nc, associated with cumulative displacement demands.

Subcritical scattering from buried elastic sphere based on subsonic Rayleigh waves
Journal of Ocean Engineering and ScienceThis study investigates the scattering characteristics of a buried elastic sphere under plane wave subcritical incidence at low-frequency. As the penetrating wave in sediment at subcritical angles transitions to an evanescent wave, it decays along the ...
