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 ...

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

open access: yesEarthquake 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.

Empirical Model of Post‐Earthquake Restoration Time for Building Components Based on Data From the 2022 Fukushima‐ken Oki Earthquake in Japan

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2897-2915, September 2026.
ABSTRACT Estimation of the time required for damaged building components to return to their pre‐earthquake conditions through repair is a critical element in assessing the seismic resilience of buildings, and it requires consideration of uncertainty.

Repeatability and Parasitic Out‐of‐Plane Motion in Controlled Rocking Structures With Cylindrical Columns: Results From Triaxial Shake Table Tests

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2930-2947, September 2026.
ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

From One Disaster to Another: Environmental Memory, Automobility, Suburbanisation and the Canterbury Earthquakes 2010–2011

open access: yesKōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 3, September 2026.
Broadly taking up Amitav Ghosh's (2016) comment that when it comes to climate change ‘we seem to learn nothing; our historical imagination is very limited’, this article argues that disregarding environmental memory, and past knowledge to plan a more resilient future, the Canterbury Earthquakes 2010–2011 continued and enabled suburbanisation and an ...

Viscoelastic Response of Crosslinked Rubber: Coarse‐Grained Molecular Dynamics and Time‐Temperature Superposition

open access: yesMacromolecular Theory and Simulations, Volume 35, Issue 5, September 2026.
Coarse‐grained molecular dynamics simulations reveal how crosslinking governs deformation and viscoelasticity in rubber networks. Crosslinks promote molecular‐chain orientation and preferentially carry deformation stress. Increasing crosslink density slows stress relaxation, lowers the loss tangent peak, and raises the equilibrium modulus, while stress
