Stress triggering effect on the 2022 Honghe MS5.0 earthquake with historical strong earthquakes

open access: yesGeodesy and Geodynamics
The 2022 Honghe MS5.0 seismic event is intriguing due to its occurrence in the south of the Red River Fault, an area historically lacking seismic activities greater than MS5.0.

Spatial heterogeneity in basin hydrology and hydropower potential: Implications for climate resilience and economic development in Nepal

open access: yesRiver, EarlyView.
Abstract Nepal's vast hydropower potential is central to its long‐term economic development; however, it exhibits pronounced spatial heterogeneity and is increasingly vulnerable to climate‐induced risks. This study employs an integrated, Basin‐scale analytical framework to evaluate the hydrological productivity and economic viability of major river ...

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

open access: yesSustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Computational intelligence model for predicting the compressive strength of FRP‐confined concrete column

open access: yesStructural Concrete, EarlyView.
Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Seismic study of the crust and upper mantle structure in eastern Asia using ambient noise correlation and earthquake data

open access: yes, 2011
Seismic methods using natural earthquakes are commonly applied to investigate the velocity structures of the crust and upper mantle. Among all these methods, seismic tomography is one of the most powerful tools to image the earth’s structure.

Assessing the fire resistance of damaged reinforced concrete frames: A comparative study between 2D and 3D frames

open access: yesStructural Concrete, EarlyView.
Abstract Post‐earthquake fires pose a significant threat to urban environments, with potentially catastrophic consequences for buildings and infrastructure. To enhance understanding and mitigate these risks, this study conducts a comparative analysis of post‐earthquake fire (PEF) in two‐dimensional (2D) and three‐dimensional (3D) reinforced concrete ...

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

open access: yesStructural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.
