Integrated seismic damage scenario and resilience assessment using multimodal data and support vector machine, a case study of Jiangyou City, Southwestern China

Geomatics, Natural Hazards & Risk
Seismic damage scenario and resilience assessment are essential for disaster prevention and urban planning, but traditional in-situ fieldwork is resource-intensive and costly at large scales. This study introduces an integrated geospatial framework using

High‐Resolution Regional Seismic Loss Assessment of Reinforced Concrete Bridges Using Component‐Level Fragility Models and Repair Cost Estimations

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 301-318, February 2026.
ABSTRACT This study develops a high‐resolution regional seismic loss assessment framework for reinforced concrete (RC) bridges, focusing on direct losses due to bridge repair and replacement. Indirect losses tied to traffic downtime, business disruption, delayed recovery, etc., can also be attributed to bridge damage but are considered outside the ...

Seismic Structural Response and Loss Estimation for Dense Urban Districts Using Neural Network Parameterized Gaussian Process

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 397-412, February 2026.
ABSTRACT Earthquakes pose a major threat to urban areas, causing fatalities, injuries, and significant economic losses. This study proposes a Gaussian process parametrized by deep neural networks (DNN–GP) as an efficient surrogate for assessing seismic losses of building structures at a regional scale.

Semi‐Active Movable Shear Keys for Seismic Response Control of Bridges

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 483-499, February 2026.
ABSTRACT The size of the joint gaps plays a significant role in the dynamic performance of bridges. This has recently motivated the consideration of movable shear keys (MSKs), pioneered by the corresponding author, to enhance bridge performance by changing the bridge support/boundary conditions.

Numerical study of PPVC modular steel constructions (MSCs) with selected connection strategies under varied earthquake scenarios

Results in Engineering
Modular steel construction (MSC) represents an innovative approach in civil engineering. Yet, the complexities of its structural response to seismic forces are not fully understood, nor is the practicality concerning its connection systems.

Predicting Seismic Debris Distributions of Collapsed Unreinforced Masonry Structures Through Physics Engines and Machine Learning Algorithms

Earthquake Spectra, Volume 42, Issue 1, February 2026.
Unreinforced masonry (URM) structures are widespread worldwide, particularly in older urban districts. However, URM buildings—particularly those constructed before the introduction of modern building codes—are highly vulnerable to seismic hazard, and prone to experiencing local and/or global failures when subjected to significant horizontal shaking ...

Robustness assessment of reinforced concrete structures for different failure scenarios

Structural Concrete, Volume 27, Issue 1, Page 279-313, February 2026.
Abstract This study describes the robustness assessment of 3D reinforced concrete structures analyzing the response of the 2D frames in different design configurations and failure scenarios. The structures are characterized by both frames with wide beams and seismic‐resistant frames with deep beams.

Experimental evaluation of reinforced concrete columns produced with natural perlite aggregates under cyclic loading

Structural Concrete, Volume 27, Issue 1, Page 411-432, February 2026.
Abstract A total of four reinforced concrete (RC) columns were tested to compare the structural capacities of RC columns produced by natural perlite aggregates and conventional concrete. The structural performance of the RC columns made from natural perlite aggregates was compared to conventional RC columns regarding the same concrete strength levels ...

Structural Accommodation as a Coastal Adaptation Response to Sea‐Level Rise: Lessons From Europe

Earth's Future, Volume 14, Issue 2, February 2026.
Abstract Global sea‐level rise is intensifying pressures on coastal regions, increasing the need for adaptation strategies (e.g., protect, retreat, accommodate). At the same time, decision makers require a better understanding of the available responses to address the widening adaptation implementation gap.
