Optimization Method for Solving the Reasonable Arch Axis of Long-Span CFST Arch Bridges

Advances in Civil Engineering, 2019
With the continuous construction of 500 m concrete-filled steel-tube (CFST) arch bridges such as the Bosideng Yangtze River Bridge and the Hejiang Changjiang Highway Bridge, the deviation between the dead pressure line and the arch axis produced by ...

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, Volume 27, Issue 3, Page 3018-3040, June 2026.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Damage Detection Applied to a Full-Scale Steel Bridge Using Temporal Moments

Shock and Vibration, 2020
The most common damages in existing highway and railway steel bridges are related to fatigue and are, as reported in the literature, found in the structural system of the bridge deck.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, Volume 27, Issue 3, Page 3309-3324, June 2026.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Robustness of a Steel Truss Bridge Subjected to Sudden Member Breakage during the Continuous-to-Simply-Supported Transition

Buildings
Steel truss bridges are especially vulnerable in the event of a sudden loss of a load-carrying element, which can trigger a chain of failures. This paper describes a unique case study of a steel truss bridge under construction subjected to sudden member ...

Evaluation of Dynamic Load Factors for a High-Speed Railway Truss Arch Bridge

Shock and Vibration, 2016
Studies on dynamic impact of high-speed trains on long-span bridges are important for the design and evaluation of high-speed railway bridges. The use of the dynamic load factor (DLF) to account for the impact effect has been widely accepted in bridge ...

Temperature Field and Gradient Effects for Concrete-Filled Steel Tubular Truss Arch Bridges Under Construction

Buildings
Long-span concrete-filled steel tubular truss arch bridges are extremely sensitive to thermal effects during cantilever construction, with non-uniform temperature distributions arising from mutual shading between members.

Study on solar-induced temperature field and thermal effects of double-layer steel truss girder bridge based on monitoring data

Case Studies in Thermal Engineering
The high thermal conductivity of steel can lead to significantly non-uniform temperature fields in long-span double-layer steel truss girders under solar radiation, thereby inducing unfavorable thermal effects on structural performance and construction ...

Theoretical Study Regarding the General Stability of Upper Chords of Truss Bridges as Beams on Continuous or Discrete Elastic Supports

Infrastructures
New or in-service truss bridges, with or without upper bracing systems, may display instability phenomena such as general lateral torsional buckling of the upper chord.
