Abstract: Previous satellite estimates of internal tides are usually based on 25 years of sea surface height (SSH) data from 1993 to 2017 measured by exact-repeat (ER) altimetry missions. In this study, new satellite estimates of ...

Abstract: The disintegration of the equatorward-propagating K1 internal tide in the South China Sea (SCS) by parametric subharmonic instability (PSI) at its critical latitude of 14.52°N is investigated numerically. The multiple-source ...

Abstract: Extending an earlier attempt to understand long-range propagation of the global internal-wave field, the energy E and horizontal energy flux F are computed for the two gravest baroclinic modes at 80 historical moorings ...

Abstract: New estimates of mode-1 M2 internal tide energy flux are computed from an extended Ocean Topography Experiment (TOPEX)/Poseidon (T/P) altimeter dataset that includes both the original and tandem tracks, improving spatial ...

Abstract: Using a set of 80 globally distributed time series of near-inertial and semidiurnal energy E and energy flux F computed from historical moorings, the group velocity ?g ≡ FE?1 is estimated. For a single free wave, observed ...

Abstract: Precast concrete frames have been widely used, though little is known about their fragility under the combined influence of seismic excitation and corrosion. In this study, one four-story precast concrete frame with different ...

Abstract: This paper focuses on the maintenance decision of vulnerable parts that need rehabilitating within the design service period under repetitive vehicular loads in steel bridges based on the time-variant performance deterioration ...

Abstract: Fire is an accidental, severe hazard for bridges during their lifetime. Hangers in suspension bridges are among the most vulnerable components with respect to the hanger fatigue effect, and fatigue performance after fire ...
