Skew Effect on Box Girder Bridge

2021
This study presents the effect of the skew angle on a simply supported box girder bridge. CSiBridge v.20 software is used for the analysis which is based on the finite element method. The mesh size is selected from the convergence study. The variation of absolute bending moment, shear force and vertical deflection due to dead load and live load for ...

Box Girder Bridge Design

Engineering Journal, 1967
This paper discusses the coordinated design research program conducted under the sponsorship of the United States Steel Corporation, on the subject of steel box girder bridges. The assigned objective of this investigation was the development of design theory, methods and specifications for steel box girder bridges of short to medium span lengths ...

Approximations for Moments in Box Girders

Journal of Structural Engineering, 1985
Simple design approximations are presented for determining the transverse moments in single‐span, single‐cell concrete box girder bridges. Five representative loading cases are considered which can be used in combination to model a range of vertical dead and live loading and wind loading. The design approximations are based on the analysis of the cross

Steel Box Girder Bridges

Engineering Journal, 1973
The steel box girder bridge, because of its structural efficiency and aesthetics, has become increasingly popular as a bridge type. Because of four unfortunate erection accidents of box girder bridges in Austria, the United Kingdom, Australia, and Germany, this type of structure has received much recent attention.

Strengthening Concrete Box Girder Bridges

Journal of Structural Engineering, 1990
There is, at a theoretical level, a direct relationship between the effects of prestressing, temperature, support settlement, and creep redistribution in concrete box girder bridges. At a more practical level, the net effect of thermal gradients or creep redistribution is to impose a positive secondary moment onto the structure, which can be balanced ...

Analysis of Box Girders with Diaphragms

Journal of the Structural Division, 1968
Analyses based on thin-walled beam theory are presented for multicell box girders of deformable cross section. The influence of flexible interior diaphragms on stresses arising from deformation of the cross section is investigated for torsional loadings and box-cell properties appropriate for steel and reinforced concrete highway bridges.

Externally Prestressed Steel Box Girder Bridge

Applied Mechanics and Materials, 2012
With a small cross section, a light deadweight and a convenient replaceable tendon, externally prestressed bridges have many special traits compared with other bridges. With a practical case, this paper analyzes the design of externally prestressed steel box girder bridges, which contains the bridge span, beam construction, externally prestressed ...

Box Girder Bridge Diaphragms with Openings

Journal of the Structural Division, 1979
The diaphragms considered in this study are of the type frequently met in box girder bridges supported on single slender piers. The outside loads are assumed to be transmitted from the bridge main girders to the inclined (or vertical) surfaces of the diaphragms in the form of uniform shearing forces.

Bracing for composite box girder bridges

Canadian Journal of Civil Engineering, 1984
For steel–concrete composite box girder bridges, the steelwork is generally erected first and then the concrete deck cast. During construction the girder may be subjected to a variety of construction loads. If the girder is a flexible open section, and lacks distortional or torsional stiffness, the cross section will deform or twist excessively; such ...

Steel–Concrete Composite Box Girder Bridges

1999
This chapter focuses on straight steel–concrete composite box-girder bridges. A single box girder with multiple cells is economical for very long spans. Multiple webs reduce the flange shear lag and also share the shear forces. A composite box section usually consists of two webs, a bottom flange, two top flanges and shear connectors welded to the top ...
