IN MEMORIAM. CONRAD P. HEINS Septem Decem During the past decade, there has been extensive use of steel box girders for straight and curved highway and transit structures'14To meet the need for use of such structural elements, design criteria had to be established.
Therefore, the purpose of this paper is to present information relative to the design criteria. particularly useful when curvature in plan is required.
This publication provides guidance on the design of composite box girder bridges, generally in accordance with BS The guide describes features of initial and detailed design and explains how the Standard is applied to the design of these structures.

Steel box girders are also used as stiffening girders of suspension bridges. For such applications an ‘aerodynamically shaped’ cross section profile is used.
[top]Curved bridges. Where the road is curved in plan, box girders can be curved to suit, which ensures that the cantilevers are of constant length. ADVERTISEMENTS: After reading this article you will learn about the design of curved bridges.
Curved bridges are normally provided for viaducts and interchanges where divergent traffic lanes are converted into a multilane bridge or over-bridge and vice versa. One such example is the Second Hooghly Bridge at Calcutta with six-lane divided carriageway on the main [ ].
This book reflects the practical experience the authors have gained in analyzing the box girder and the truss used in bridge engineering; the straight and curved box girder bridge, the truss bridge, and the arch-stiffened truss bridge are considered, whereby bending and torsional stresses, lateral buckling and vibrations are investigated.
This document consists of a comprehensive steel girder bridge design example, with instructional commentary based on the AASHTO LRFD Bridge Design Specifications (Second Edition,including interims for through ).
The design example and commentary are intended to serve as a guide to aid bridge design engineers with the implementation. The Proceedings of the NATO Advanced Study Institute on Analysis and Design of Bridges held at ~e§me, lzmir, Turkey from 28 June to 9 July are contained in the present volume.
The Advanced Study Institute was attended by 37 lecturers and participants from 10 different countries. The. F.1 bAckground This section contains a procedure developed to extend the application of jointless bridges to curved steel I-girder bridges (Doust ).
Several limitations must be ob- served when using the suggested approach that reflect the range of parameters consid- ered in its development.

often necessary during steel multi-girder bridge erection. For curved, multi-span structures over variable terrain, this often warrants a visual layout based upon feasible crane placements.

footpath on either side having spans as shown in Fig. is to be designed for single lane of IRC Class R or 2 lanes of IRC Class A loading. Give brief outlines for calculating the bending moments and shear forces and draw the bending moment and shear force diagrams.
Figure In addition, since the girders are closed they tend to remain dry and there are fewer places for debris and other corrosion causing agents to collect. However, the primary advantage of box girders is the large torsional stiffness that makes the girders ideal for use in curved interchanges for which the bridge.
petitive with the steel beam design when the unit steel price, in place and painted, is more than $1 per pound ($ per ton). Typical unit prices on curved steel girders range from $ to $ per pound.
Precast beams are competitive with cast-in-place concrete box girders when the in-place unit concrete price exceeds $ per cubic yard. When steel girders are curved in plan, torsional effects are introduced and these effects must be considered when designing the beams.
Society gains in many ways from the benefits delivered by the infrastructure development. Landmark steel bridges involve good design, they are fast to build. The impact of seven three-span continuous single box girder bridges, with overall span lengths ranging from to m (– ft), due to vehicles moving across rough bridge decks is analyzed.
The box girder is divided into a number of thin-walled beam elements. Both warping torsion and distortion are considered in the study. Guidelines for analysis methods and construction engineering of curved and skewed steel girder bridges Donald Woodrow White, National Research Council (U.S.).

Bouassida, E. Bouchon, P. Crespo, P. Croce, L. Davaine, S. Denton, M. Feldmann, R. Frank. A set of equations was developed to estimate the maximum mechanical elements and midspan deflections of plan-curved steel I-girder bridges. These formulas were obtained from a statistical correlation analysis based on the results of 54 tridimensional finite-element models corresponding to different 3-span continuous curved bridges.

Steel box girders are usually adopted in very long span bridges where it is necessary to keep the self-weight of the structure as minimum as possible. Depending on the width requirements single and multiple cell girders are selected.
Steel Box girders are used for footbridges curved in plan and also for bridges with longer spans.
