Study on Shear Lag Effect of Composite Box Girder Bridge with Corrugated Steel Webs

Chemical Engineering Transactions, 2017
The corrugated steel webs composite box girder bridge is a new bridge structure with corrugated concrete webs with fold effects, which can replace traditional concrete webs. Compared with traditional concrete web box girder, the application of steel webs

Simulation-Based Tracking Test and Optimization of Large-Tonnage Box Girder Transport with Trolley on an Erected Bridge

Advances in Civil Engineering, 2022
In the construction of large-tonnage box girder, the construction load of box girder transport is generally greater than the operating load in highway industry; therefore, it is a crucial task to carry out accurate simulation and optimization on bearing ...

Free Shrinkage Strains of Box Girders with Concrete Overlays

Infrastructures, 2023
The aging of reinforced concrete structures is one of the biggest concerns in civil engineering today since billions of dollars are spent annually on deck repairs and replacements. This study focuses on the rehabilitation of reinforced concrete box girders used in bridge construction.

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

Structural Concrete, EarlyView.
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 ...
