Approximate Analysis of Concrete Box Girder Bridges

Journal of Structural Engineering, 1988
The purpose of this paper is to show that the actual three-dimensional behavior of a box-girder bridge as predicted by a folded-plate, finite-strip, or finite-element analysis can be approximated by using some simple membrane equations in conjunction with a plane-frame analysis.

Cracking in a Curved, Reinforced Concrete Box Girder Bridge

Advances in Structural Engineering, 2002
A study to monitor a multi-span reinforced concrete bridge was recently completed. The bridge is curved, with a non-prismatic three-cell box cross section. Extensive field testing was performed to evaluate the causes and effects of large shear cracks.

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.

Load Testing of a Deteriorated Concrete Box Girder Bridge

Advances in Structural Engineering, 2002
This 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.

Overlay for Concrete Segmental Box-Girder Bridges

Journal of Bridge Engineering, 2000
Concrete overlay cracking and delamination were noticed on a concrete segmental box-girder bridge. Analytical investigation and field and laboratory examinations were conducted to identify the major factors causing the defects. The time-dependent stress distribution and its change in the overlay and along the interface between the overlay and the ...

Temperature and Stress Distributions in Concrete Box Girder Bridges

Journal of Structural Engineering, 1990
Temperature 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 ...

Preliminary Design System for Concrete Box Girder Bridges

Journal of Computing in Civil Engineering, 2001
A neural network-based design system is presented in this paper for preliminary design of concrete box girder bridges. The system is based on a loose coupling model that integrates the artificial neural network and the fuzzy network to perform the task of noisy data filtering, knowledge extraction, and candidate synthesis.

Analysis and Design of Prestressed Concrete Box Girder Bridge

2022
AbstractBridge 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.

Folded plate action for concrete box girder bridges

IABSE Congress Reports, 2016
<p>As already described in begin eighties in Structural Engineering Document 1 “Concrete Box-girder Bridges” [1] the Folded Plate Action of torsion stiff concrete box-girder bridges cannot be disregarded. But nowadays many designs are made by 3D Finite Element Analysis using 2D plate/shell elements, although the number of loading cases described ...

Structural Redundancy of Prestressed Concrete Box Girder Bridges

Transportation Research Record: Journal of the Transportation Research Board, 2016
Bridges are usually designed and evaluated on the basis of member strength and serviceability criteria; however, they are expected to have sufficient levels of reserve strength and multiple paths to resist collapse should any of their members get damaged or exceed their nominal strength capacity.
