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

Earthquake 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

Earthquake 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.

Effects of Wall‐to‐Floor Interactions on Seismic Response of Platform‐Type CLT Buildings

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2880-2896, September 2026.
ABSTRACT Platform‐type cross‐laminated timber (CLT) buildings feature discontinuous wall segments supported by CLT floors. In practice, CLT floors are often treated as rigid diaphragm, yet the wall‐to‐floor interactions (WFIs) associated with flexibility of floors remain insufficiently investigated during seismic performance assessment.

Frequency-independent damping models for a high-rise building with simultaneous horizontal and vertical seismic motions

Frontiers in Built Environment
Recent seismic analyses indicate that the structural damping ratio should be considered frequency-independent, for safe and accurate estimations. In response, damping models like the Wilson–Penzien (WP) damping model, that is one of the modal damping ...

Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration

Advanced Functional Materials, Volume 36, Issue 65, 13 August 2026.
High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...

Bias‐Engineered Synthetic Antiferromagnets Hosting Sub‐20 nm Zero‐Field Skyrmions at Room Temperature

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A fully compensated synthetic antiferromagnet (SAF) multilayer exhibits a uniform state at zero field, without skyrmions. We use a SAF bias system to provide RKKY‐mediated exchange bias to the SAF multilayer, promoting zero‐field skyrmion stabilization and polarity control.
