A Noncontact Methodology for Disengagement Monitoring of High‐Speed Railway Bridge Bearings Based on Bearing‐to‐Beam Displacement Relation Under Round‐Trip Trains

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Bearings are critical components of bridges and are susceptible to various forms of deterioration under the action of traffic loads and complex environmental conditions. Existing methods for assessing the condition of bearings, including visual inspections, force sensors, cameras, and vibration sensors, still present challenges in accurately locating ...

Numerical study on steel plate girders – Minimum bending rigidity of intermediate transverse stiffeners

ce/papers, Volume 8, Issue 6, Page 1277-1283, December 2025.
Abstract Steel plate girders take advantage of transverse stiffeners giving web lateral support along the span and increasing the shear resistance. In addition, transverse stiffeners play a key role in mitigating web buckling by supporting the edges of the web panel and thus anchoring the axial compression resulting from the tension field action.

Perspectives on the incorporation of self‐healing in the design practice of reinforced concrete structures

Structural Concrete, Volume 26, Issue 6, Page 7284-7311, December 2025.
Abstract Self‐healing concrete, with its ability to autonomously repair damages, holds promise in enhancing its structural durability and resilience. Research on self‐healing concrete in the past decade has advanced in understanding the mechanisms behind healing, exploring various healing agents, and assessing their effectiveness in concrete structures.

Adaptive stochastic deterioration modeling for evaluating pavement survey schedules in relation to performance and management cost

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6701-6721, 29 December 2025.
Abstract Pavement performance impacts transportation mobility, safety, and comfort, with timely maintenance relying on field survey data. However, frequent surveys are costly and impractical. This study examines how survey timing and frequency influence maintenance events and pavement deterioration to optimize management strategies.

AASHTO rehber teknik şartnamesine (AASHTO-GSID) göre köprülerde sismik yalıtım tasarımı

, 2021
Seismic isolation has a common use in bridge engineering. According to the innovations in material science and analysis methods seismic isolation design paves the way for designing more economic and esthetic bridges.Seismic behavior of bridges depends on the mass of superstructure and stiffness of the substructure.

Settlement Analysis of a Large Pile Group Supporting an LNG Storage Tank

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 16, Page 3858-3879, November 2025.
ABSTRACT Liquefied natural gas (LNG) storage tanks are often supported by large pile groups (>100 piles). The design of such foundations is generally governed by settlement rather than bearing capacity. However, minimal information is available regarding the settlement performance of the LNG tank foundations. This article first presents a comprehensive
