Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Comparative Fatigue Failure Analysis of Axle Shafts in Two Front Wheel Drive Vehicles

open access: yesAutomotive Experiences
Axle shafts are critical components of vehicle powertrain systems, providing torque and load transfer between the differential system and the wheels. Common causes of axle shaft failures include manufacturing and design defects, lack of maintenance, raw ...

Method for determining design life of ballastless way

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2017
The problem of the scope of ballastless track superstructure (BTS) and its service life currently is urgent. Due to the high traffic density at the Test Loop of JSC "VNIIZhT" for a short period of time it is possible to get an idea of BTS service life ...

Side‐by‐side long‐term performance assessment of GFRP‐ and steel‐reinforced concrete bridge decks

open access: yesStructural Concrete, EarlyView.
Abstract The corrosion‐induced deterioration of steel‐reinforced bridge decks is a service life concern, especially in cold regions, where the use of deicing chemicals is common. To address this issue, glass fiber‐reinforced polymer (GFRP) reinforcement has received growing attention, owing to the GFRP's resistance to conventional corrosion.

A probabilistic framework for modeling chloride‐induced corrosion and related load‐deformation behaviour of reinforced concrete

open access: yesStructural Concrete, EarlyView.
Abstract Chloride‐exposed reinforced‐concrete structures often suffer localized corrosion, so corrosion initiation time and average steel loss are poor indicators of structural performance. This paper presents a spatially resolved, proof‐of‐concept framework that couples diffusion‐based chloride ingress and initiation with a localized morphology model ...

Real-Time Axle-Load Sensing and AI-Enhanced Braking-Distance Prediction for Multi-Axle Heavy-Duty Trucks

open access: yesApplied Sciences
Accurate braking-distance prediction for heavy-duty multi-axle trucks remains challenging due to the large gross vehicle weight, tandem-axle interactions, and strong transient load transfer during emergency braking.

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

open access: yesJournal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.
