Fatigue assessment of 100 years old riveted truss railway bridge [PDF]

open access: yesPrzegląd Komunikacyjny, 2021
Fatigue is one of the most often reasons for failure in existing steel bridges, particularly with riveted structure. Therefore fatigue assessment is always the most important part of the complex evaluation of existing steel bridges.

Non‐invasive mark–resight surveys for brown bears: Incorporating spatial information to improve landscape‐scale monitoring of density and distribution

open access: yesEcological Solutions and Evidence, 2023
Effective wildlife monitoring and management are reliant on unbiased estimators of population parameters. Most standard survey approaches ignore spatial pattern in the data although spatial relationships can be leveraged to produce more efficient designs

Design a geothermal bridge deicing system for an in-service bridge

open access: yesSymposium on Energy Geotechnics 2023, 2023
Deicing on bridge deck surfaces is essential to ensure the safety and mobility of motorists during severe winter weather. Conventional snow/ice removal chemicals such as salt cause bridge corrosion and provoke environmental issues. Therefore, a new external geothermal heating system for bridge deck deicing and snow melting has been proposed, which can ...

Corrosion Fatigue Assessment of Bridge Cables Based on Equivalent Initial Flaw Size Model

open access: yesApplied Sciences, 2023
Bridge cables under traffic loads are more prone to failure during the service life due to the corrosion–fatigue coupling effect. In this study, a novel lifespan model based on the equivalent initial flaw size (EIFS) theory is established to analyze the ...
