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 ...

Experimental Study and Numerical Analysis of Hydration Heat Effect on Precast Prestressed Concrete Box Girder

Buildings
Large-span precast prestressed concrete box girders have been widely used in bridge construction near or across the sea. However, this would easily lead to a hydration heat problem, including large initial tensile stress and concrete cracks during the ...

Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.
