Bending performance of prefabricated ultra-thin UHPC unit plate reinforced orthotropic steel bridge decks

Frontiers in Materials
To address the challenges related to lengthy construction period, complex maintenance requirement, and the elevated risk of shrinkage cracking associated with cast-in-place UHPC reinforcement of orthotropic steel bridge decks. This paper proposes a novel

Development of a lamella‐model to evaluate stresses caused by hot asphalt installation

ce/papers, Volume 7, Issue 3-4, Page 56-61, September 2024.
Abstract On road‐bridges hot asphalt is installed to provide a level and waterproof surface. That wearing surface, however, needs occasional renewal. On a number of steel highway‐bridges it has been observed that after such asphalt‐renewal fatigue‐cracks have increasingly occurred at the welds of orthotropic bridge‐decks.

Repairing fatigue damage on an orthotropic steel deck road bridge

, 2017
Steel bridges with orthotropic decks are prone to fatigue due to increased heavy vehicle traffic. An example is the 1982 A5 Highway Bridge over the Mannheim–Basel and Karlsruhe–Stuttgart rail tracks in Germany.

Statistical Analysis of Stress Signals from Bridge Monitoring by FBG System

Sensors, 2018
In this paper, a fiber Bragg grating (FBG)-based stress monitoring system instrumented on an orthotropic steel deck arch bridge is demonstrated. The FBG sensors are installed at two types of critical fatigue-prone welded joints to measure the strain and ...

Crack growth prediction of deck plate-stiffener joints in orthotropic steel bridge decks

, 2013
Orthotropic deck structures are used in many steel bridges. Due to the typical detailing applied as around 1970, a significant number of deck structures constructed in that period suffer from fatigue damage.

Systematic Rehabilitation Techniques and Dynamic Analysis of Bridge Deck System with Concrete-Filled Steel Tube Arches

Buildings
Due to prolonged heavy traffic, the Wuhan Changfeng Bridge has experienced extensive cracking in its main girder structure. Of the bridge’s 60 crossbeams, 51 (85%) have developed cracks, while the deck pavement over the steel beams has accumulated a ...
