Need for Diaphragms in Concrete Box Girders

Journal of the Structural Division, 1971
The action of diaphragms in single-cell concrete box girders is covered with particular reference to torsional loading. A simple analysis of the distortion of boxes is presented in which the webs are treated as beams on elastic foundations. An empirical factor for the effective span of the top and bottom plates has been selected to agree with ...

Transverse assessment of a concrete box girder bridge

Proceedings of the Institution of Civil Engineers - Bridge Engineering, 2017
This paper looks at the beneficial effects of geometric arching from haunches, web continuity and compressive membrane action in the design and assessment of box girder top slabs. The paper initially reviews tests relevant to arching action in box girders and then analyses recent tests on box girder slab strips.

Temperature variation of concrete box girder bridge

Frontiers of Architecture and Civil Engineering in China, 2009
On the basis of theoretical analysis and measurement on site, the temperature gradients and its variation on concrete box girder bridges resulting from ambient temperature, solar radiation, and structural temperature fields were discussed. With the help of the heat transfer theory and finite element method (FEM), the heat flux of the surface of ...

Concrete Box-Girder Bridges

1982
<p>The box girder is today the most widely used superstructure in cocnrete bridge construction. The aim of this document is to relieve the engineer of the study of today's hardly surveyable mass of literature on the subject so that he can better devote that time to the actual design of the bridge.

Design and Analysis of a Prestressed Concrete Box Girder

1994
New 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.
