The Synthesis and Mechanism of AlB2‐KAlF4 Composites Prepared by Self‐Propagating High Temperature Synthesis Method

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
AlB2‐KAlF4 composites were fabricated via SHS using Al and KBF4. Phase evolution, microstructure, and reaction mechanism were characterized. KBF4/Al melting initiates the reaction; BF3‐Al redox yields AlB2 and KAIF4 with distinct morphologies. ABSTRACT Using Al and KBF4 as raw materials, AlB2‐KAlF4 composites were synthesized by self‐propagating high ...

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Weak‐Story Mitigation and Drift Redistribution in Moment‐Resisting Frames Using Stepping Rocking Walls

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2760-2780, September 2026.
ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.

Applied Element Modelling of Out‐Of‐Plane Instability in Boundary Elements of Thin RC Walls

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2800-2817, September 2026.
ABSTRACT Recent earthquakes in Chile (2010) and New Zealand (2011) caused extensive damage to buildings featuring reinforced concrete (RC) structural walls, with observed failure modes including out‐of‐plane instability of slender walls. This buckling‐type response under combined in‐plane and out‐of‐plane loading has also been documented in ...

Non‐Physical Barrier Design and Environmental Conditions Alter Routing and Survival of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) in the Sacramento‐San Joaquin River Delta

open access: yesRiver Research and Applications, Volume 42, Issue 7, Page 1551-1561, September 2026.
ABSTRACT Pacific salmon face substantial challenges when migrating through anthropogenically modified river systems, such as the Sacramento‐San Joaquin River Delta (the Delta). Non‐physical behavioral barriers, such as the bioacoustic fish fence (BAFF), are one potential solution for guiding fish away from hazards without obstructing water flow ...
