Comparison of Scaling Ground Motions Using Arithmetic with Logarithm Values for Spectral Matching Procedure

open access: yesShock and Vibration, 2020
In recent studies, spectral matching is the most commonly proposed method for selecting earthquake records for time-history analysis of structures. However, until now, there have been no serious investigations of the effects of coordinate values on the ...

Barriers and Bridges in Abating Coastal Eutrophication [PDF]

open access: yesFrontiers in Marine Science, 2019
Over the past 30 years concerted campaigns have been undertaken to reverse nutrient-driven eutrophication in coastal waters in Europe, North America, Asia, and Australia. Typically, eutrophication abatement has proven a more recalcitrant challenge than anticipated, with ecosystem improvements only recently beginning to emerge or falling short of goals.

Impact of Coastal Infrastructure on Ocean Colour Remote Sensing: A Case Study in Jiaozhou Bay, China

open access: yesRemote Sensing, 2019
Spatial and temporal ocean colour data are increasingly accessible through remote sensing, which is a key tool for evaluating coastal biogeochemical and physical processes, and for monitoring water quality.

Offshore Bridge Detection in Polarimetric SAR Images Based on Water Network Construction Using Markov Tree

open access: yesRemote Sensing, 2022
It is difficult to detect bridges in synthetic aperture radar (SAR) images due to the inherent speckle noise of SAR images, the interference generated by strong coastal scatterers, and the diversity of bridge and coastal terrain morphologies.

Energy Characteristics of Acoustic Emission at the Volume-Expansion Point of a Rock Bridge: A New Insight into the Evolutionary Mechanism of Coastal Cliff Collapse

open access: yesJournal of Marine Science and Engineering, 2021
The recession of a coast can destabilize coastal cliffs. The stability of a cliff is controlled by a rock bridge. Identifying the volume-expansion point of rock bridges is crucial to assess cliff stability, but currently there are few identifying methods.

Study on the Time-dependent Reliability of Corroded Reinforced Concrete Bridge Structures due to Ship Impact

open access: yesAdvances in Civil Engineering, 2022
The cumulative damage caused by chloride ion erosion to coastal bridge structures reduces the ship impact resistance of channel bridge structures and leads to changes in reliability of bridge structures on ship impact.

Dynamic performance of simply supported girder bridges subjected to successive earthquake-tsunami events

open access: yesAdvances in Bridge Engineering, 2022
Coastal bridges are susceptible to severe damage when subjected to successive earthquake-tsunami events. Previous studies mainly consider the tsunami loadings as hydrodynamic forces, whereas other hydrodynamic forces such as uplift and slamming forces ...

Hurricane vulnerability of coastal bridges using multiple environmental parameters [PDF]

open access: yesInternational Journal of Safety and Security Engineering, 2016
Hurricanes and other severe storms have proven themselves to be one of the major threats to transportation assets throughout the world, particularly to bridges located along coastal areas. Bridges as key components of transportation networks have shown to be vulnerable to hurricane-induced wave and surge forces. A large number of bridges along the U.S.
