Combined Vertical and Horizontal Components of Near‐Source Earthquakes and Impact on Base‐Isolated Structures

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 781-803, March 2026.
ABSTRACT Over recent decades, the collection of seismic data has improved the understanding of near‐fault ground motion effects, which involve both horizontal and vertical components. Among the most significant effects are fault‐normal directivity, which concentrates seismic energy into an intense, long‐period pulse, and fault‐parallel fling step ...

Structural Health Monitoring of a Unidirectional Isolation Bridge: Bidirectional Seismic Behavior, Stochastic Model Updating, and Prediction

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 759-780, March 2026.
ABSTRACT Accurate mechanical characterization of civil engineering structures after construction remains challenging due to the unique complexities of each structure, including geometric configurations, imperfect design modeling assumptions, soil conditions, and pervasive uncertainties in actual operational environments. Leveraging actual measurements,

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Seismic Vulnerability of Bridges Using Simplified Models

, 2002
Currently, numerous existing bridges can suffer damage of different considerations when subjected to seismic actions of certain magnitude. The failure of these systems can be the origin of enormous economical losses(direct and indirect) that can collapse economic activities.Therefore, simplified and reliable evaluation tools of the current state of ...
