Detection of Rupture Damage Degree in Laminated Rubber Bearings Using a Piezoelectric‐Based Active Sensing Method and Hybrid Machine Learning Algorithms

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Laminated rubber bearings may exhibit rupture damage due to factors such as temperature variations and seismic activity, which can reduce their isolation performance. Current detection methods, including human‐vision inspection and computer‐vision inspection, have certain limitations in accurately assessing the degree of rupture damage.

Simulated Slidequakes: Insights From DEM Simulations Into the High‐Frequency Seismic Signal Generated by Geophysical Granular Flows

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 8, August 2024.
Abstract Geophysical granular flows generate seismic signals known as “slidequakes” or “landquakes”, with low‐frequency components whose generation by mean forces is widely used to infer hazard‐relevant flow properties. Many more such properties could be inferred by understanding the fluctuating forces that generate slidequakes' higher frequency ...

Agenda Setting in Media Coverage of Natural Disaster Exogenous Events: The 9.5 Sichuan Ganzi Luding Earthquake as an Example

, 2023
Disaster reporting, as a special kind of news reporting, requires the media to assume more moral and social responsibilities. At present, the development of disaster reporting faces many dilemmas, such as the substitution of traditional media by new ...

Historical changes in the distribution of the Sichuan golden snub‐nosed monkey (Rhinopithecus roxellana) in Sichuan Province, China

Ecology and Evolution, Volume 14, Issue 4, April 2024.
Historical changes in the distribution of the Sichuan golden snub‐nosed monkey were identified. Between 1980 and 2000, there was a sharp decline in the distribution area of the Sichuan golden snub‐nosed monkey. The boundary of the distribution area for the Sichuan golden snub‐nosed monkeys in Sichuan Province has significantly shifted northward ...

Impact of Earthquake on Rainfall Thresholds for Sustainable Geo-Hazard Warnings: A Case Study of Luding Earthquake

Sustainability
This study explores the impact of the 2022 Mw 6.8 Luding Earthquake on various geo-hazards and their corresponding rainfall thresholds. Focusing on the seismic intensity VI zone in Sichuan Province, China, we analyzed 1979 geo-hazard records and hourly precipitation data from 475 stations between 2010 and 2024. Empirical ID (intensity–duration) and AC (

Effect of Bidirectional Ground Motion on the Response of Double Concave Friction Pendulum Systems

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
Recent destructions of structures due to insufficient isolator deformation capacity have led to demands for greater seismic redundancy in seismic isolation design. For a friction pendulum system (FPS), the effect of bidirectional behavior of earthquakes on the maximum response and its effect on friction heating, temperature, and in turn on the maximum ...

Construction of Knowledge Graph for Emergency Resources

International Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.
Knowledge graphs can effectively organize and represent information related to emergency resources for unforeseen sudden events. In this study, we construct a model layer for the knowledge graph of emergency resources, focused on sudden events, through the classification and analysis of unforeseen disaster measures.
