Recent Progress in Mechanoluminescence for Multi‐Dimensional Stress Monitoring

Advanced Science, Volume 13, Issue 5, 27 January 2026.
Multi‐dimensional stress visualization technology (0D point detection, 1D linear distribution, 2D planar imaging, 3D volume reconstruction) has become a focus of attention in the field of stress sensing. The transition from “points” to “multi‐dimensional spatial fields” facilitates real‐time, in situ, and high‐resolution visualization of stress ...

Tests with a Carlina-type diluted telescope; Primary coherencing [PDF]

, 2012
Studies are under way to propose a new generation of post-VLTI interferometers. The Carlina concept studied at the Haute- Provence Observatory is one of the proposed solutions. It consists in an optical interferometer configured like a diluted version of

Stress Corrosion Tests for Prestressing Steels—Part 2: Susceptibility of Quenched and Tempered Wires—Influence of Chromium

Materials and Corrosion, Volume 77, Issue 1, Page 36-45, January 2026.
Cr‐alloyed quenched and tempered prestressing steel wires were found to be as highly susceptible as non‐Cr‐alloyed ones. This finding is in contrast to the known literature. A newly developed and reproducible method for assessing susceptibility to hydrogen‐induced stress corrosion cracking was used.

Enhancing hard X‐ray beamline performance at SwissFEL through spontaneous radiation measurements

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 32-43, January 2026.
Methods using spontaneous radiation to monitor and optimize the Aramis hard X‐ray beamline are presented, together with the eight‐year evolution of these improvements and the resulting record performance.The hard X‐ray beamline (Aramis) of the Swiss free‐electron laser (SwissFEL) has been in user operation since the end of 2017 and its performance has ...

Design and field tests of a deck-extension bridge with small box girder

Journal of Traffic and Transportation Engineering (English ed. Online), 2018
A jointless bridge could fundamentally eliminate vulnerable deck joints, thereby meeting the need for sustainable development of bridges, especially for an expressway with high-speed traffic.

Effect of section geometry on development of shrinkage-induced deformations in box girder bridges [PDF]

, 2017
Non-uniform shrinkage strains can lead to significant additional deflections in large box girder bridges, leading to serviceability problems. This article examines experimentally and analytically the effect of different cross-section geometries on the ...

Improvement of the Nonlinear Damage Mathematical Model for Steel Components in Bridge Under Complex Stress

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To investigate the relationship between load, damage, and fatigue life of complex engineering components under stress, this paper modifies the existing continuous nonlinear damage model based on the distortion energy density theory to reflect the usage and stress characteristics of Q345 steel components in bridges.

Bridge-specific fragility analysis: when is it really necessary? [PDF]

, 2018
In seismic assessment of bridges the research focus has recently shifted on the derivation of bridge-specific fragility curves that account for the effect of different geometry, structural system, component and soil properties, on the seismic behaviour ...

Study on the Crack Propagation Behavior and Patterns of High‐Speed Railway Bridges Under High‐Speed Train Loading

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study focuses on simply supported railway box girder bridges with pre‐existing cracks under high‐speed train loading. A vehicle–bridge coupled vibration model is established, and three‐dimensional dynamic stress intensity factors at the crack tip under various loading conditions are obtained using the interaction integral method.
