Design and Analysis of a Prestressed Concrete Box Girder
1994New codes for the design of concrete structures in The Netherlands give designers the opportunity to utilize the possibilities of partial prestressed concrete. It will be possible in bridge construction to combine prestressing and reinforcement so that the result will be optimal; technically and economically.

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.

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.

Shear Lag Analysis in Prestressed Concrete Box Girders
Journal of Bridge Engineering, 2011Most studies on shear lag effect in box girders are only concerned about concentrated loads and uniformly distributed loads. In this paper, a finite-element method based on the variational principle is presented to analyze the effect of prestressing on shear lag in box girders.

Prefabricated Box Girder with Ultra High Performance Concrete
IABSE Reports, 2018<p>In order to solve traffic difficulty brought by the bridge construction in the city, and difficult transportation of beams, this paper puts forward the prefabricated-box-girder bicycle viaduct with ultra - high performance concrete (UHPC) through which will achieve light and thin beams, easy transportation and rapid 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 ...

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

Analyses of concrete bridge box girders
1993This work presents the parameter studies of one-cell free-support concrete box girders with a transverse diaphragms only above the supports. Some parameters have been varied such as: the girders span, the box width, the length of the side cantilevers and the thickness of the box webs.

16.16: Medium span steel‐concrete composite bridges: plate girders or box girders
ce/papers, 2017ABSTRACTIn today's environment and client's requirements, solutions for medium span road and rail bridges within the UK tend to result in an overlap between three types of steel‐concrete composite decks. From the ban and moratorium imposed on grouted post‐tensioned concrete bridges since the early 1990s, braced pairs of plate girders, twin plate ...
