Retrofitting of a Multi-Span Simply Supported Bridge into a Semi-Integral Bridge

Applied Sciences
Thousands of multi-span, simply supported beam bridges with short or medium spans have been built in China. They often suffer from problems of cracks in the link slabs over piers, and the deterioration and damage of deck expansion joints at abutments. To

Experimental and numerical study of road-bridge link slabs in fully jointless bridges using rubberized engineered cementitious composites (R-ECC)

Case Studies in Construction Materials
This paper presents a different way using crumb rubber and fine sand totally replaced for silica sand within ECC mixtures to make rubberized engineered cementitious composites (R-ECC) to solve the issues of high construction cost of the road-bridge link ...

Performance assessment of deck link slabs in multi-span bridges: a case study of the Plott Creek Bridge

Frontiers in Built Environment
The use of link-slab connections in simply supported multi-span bridge decks is a widely adopted strategy to minimize the number of expansion joints, reducing long-term maintenance issues and improving the roadway surface quality. Current design practice

Jointless and Smoother Bridges: Behavior and Design of Piles

, 2006
This report is the first of a two-volume final report presenting the findings of the research work that was undertaken to evaluate the fatigue behavior of steel highway bridges on the extra heavy weight truck corridor in Northwest Indiana. The purpose of the study was to evaluate the type and magnitude of the loads that travel along the corridor and ...

Robust Disturbance-Response Feature Modeling and Multi-Perspective Validation of Compensation Capacitor Signals

Mathematics
In high-speed railways, the reliability of jointless track circuits largely hinges on the operational integrity of compensation capacitors. These capacitors are periodically installed along the track to mitigate rail inductive impedance and stabilize ...

Novel macroscopic mechanical model for rapid and refined analysis of link slab bridges

Advances in Bridge Engineering
Debonded link slabs are commonly adopted to replace the expansion joints of existing simply supported bridges, thereby protecting the girders and piers underneath them from exposure to water and deleterious agents. The primary challenges for the accurate
