Structural Response of Concrete Box Girder Bridge

Journal of the Structural Division, 1973
Results obtained in a study of a large-scale, two-span, four cell reinforced concrete bridge model are presented. The model, which was a 1:2.82 scale replica of a prototype, had overall plan dimensions of 72 ft (21 m) long by 12 ft (3.7 m) wide. The various computer programs used in obtaining theoretical results are described and compared. Experimental

Ultimate Strength of Concrete Box Girder Bridge

Journal of the Structural Division, 1974
Results obtained in a study of a large-scale, two-span, four-cell reinforced concrete box girder model are presented. The model, which was a 1:2.82 scale replica of a prototype, had overall plan dimensions of 72 ft (21.14 m) long by 12 ft (3.66 m) wide.

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 ...

Thermal Effects on Box Girder Concrete Bridges

Key Engineering Materials, 2017
Thermal load, especially vertical temperature gradient, is an important factor that should be considered during the bridge design procedure. In the world, several researches focusing on temperature gradient was made, mostly in USA and China, but only a few analyzed actual temperature gradients measuring at European bridges.

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.

Web design of box girders concrete bridges

Engineering Structures, 2013
Abstract The purpose of this paper is to introduce a new design approach including the Ultimate Limit State (ULS) due to fatigue. Different criteria for the design of those webs are compared by means of shear-bending moment interaction diagrams, as an attempt to identify the most realistic one.
