Strengthening large concrete box-girder bridge on shear
IABSE Reports, 2010<p>In the Rijkswaterstaat Programme “Widening of the Roads”, the road capacity on the bridges across the Low-Rhine has to be increased. Because of the resulting increase on traffic loads the bridges had to be structural assessed. At the same time a large amount of diagonal cracks in the webs of the twin box-girders were discovered.

Bridge information models for construction of a concrete box-girder bridge
Structure and Infrastructure Engineering, 2012Large construction projects involve collaboration among a large number of participants with different specialised knowledge from various construction processes. A readily accessible bridge information model is needed to enable engineers to innovate prefabricated bridge construction.

Assessment and identification of concrete box-girder bridges
IABSE Reports, 2019<p>This work consists in identify and assess the properties related to material, geometry and physic sources, in a pre-stressed concrete bridge through a surrogate model. The use of this mathematical model allows to generate a relationship between bridge properties and its dynamic response, with the purpose to develop a tool to predict the ...

Load Testing of a Deteriorated Concrete Box Girder Bridge
Advances in Structural Engineering, 2002This paper reports on load testing of a continuous three cell concrete box girder bridge. The bridge is non-prismatic, curved in plan, and has skewed supports. The bridge is over thirty years old, and it was designed with a construction joint between two continuous spans and a span with a cantilever. The tests were carried out to evaluate the cause of

Temperature and Stress Distributions in Concrete Box Girder Bridges
Journal of Structural Engineering, 1990Temperature distributions in concrete bridges are nonlinear and induce self‐equilibrated stress distributions. Such distributions depend on several variables (environmental conditions, physical and material properties, and location of bridge). On the other hand, temperature and stress distributions in concrete box girder bridges depend on the cross ...

Computer Aided Concrete Box Girder Bridge Design
2004A group of computer algorithms has been built for computing main bearing parts of the bridge starting from the superstructure to the foundations dependent on the span length. This analysis refers to prestressed concrete girder bridges with box cross section.

Longitudinal stress over supports of concrete box-girder bridges
Canadian Journal of Civil Engineering, 1981This paper describes a study of the values of longitudinal moments/stresses and their distribution at sections over the supports of continuous box-girder bridges. A series of continuous box-girder bridges are analyzed using the finite element method. Results from the finite element analysis are compared with the classical beam theory which is commonly

Analysis and Design of Prestressed Concrete Box Girder Bridge
2022AbstractBridge construction has now achieved global significance. In this evolution era, prestressed box girder bridge is becoming more and more popular the bridges as it has improved serviceability, aesthetic appearance, better stability, and also economical. It has also structural efficiency.

Evaluation of a High Performance Concrete Box Girder Bridge
PCI Journal, 2000As part of the FHWA (Federal Highway Administration) High Performance Concrete Bridge Program, two full-scale truckload tests of Bridge GUE-22-6.57 were carried out. The main objectives of these tests were to investigate the static and dynamic response of the high performance concrete (HPC) structure.

Flexural response of skew-curved concrete box-girder bridges
Engineering Structures, 2018Abstract The flexural response of the box-girder bridges, having curvature and skewness together referred as skew-curved bridges, cannot be predicted by simply superimposing the individual effect of skewness and curvature due to the coupling of these effects.
