-Discusses in detail, on a clause-by-clause basis, those aspects of BS 5400-3 (as recently and extensively amended) that are the most commonly used by bridge designers. Background information and comments on practical applications that were provided in the earlier commentary (publication P085) have been updated and extended.

-This second issue of the publication has been updated to reflect changes consequent on the revision in 2000 of BS 5400-3
Composite box girder construction offers an attractive and economic form of construction for medium span highway bridges. The torsional properties of the closed section are often advantageous in reducing and simplifying the support arrangements and are 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 5400. The guide describes features of initial and detailed design explaining how the standard is applied to the design of these structures. Flow diagrams are provided as further guidance to the use of the Standard. Two worked examples are included based on the designs for actual structures. These give extracts of the design relating to the features particular to the box girder form together with a commentary on the calculations.

-Covers the design of bridge decks according to BS 5400, including the amendments to Part 3 issued in 2000. The guidance relates principally to highway bridge decks, and where the deck slab is on top of 1-section steel girders. The design principles for main beams, restraints, shear connection and slab design are presented. Includes both elastic and plastic moment resistance of beams ( non-compact and compact sections according to BS 5400 terminology). Reference is made to the Highways Agency documents that implement the use of BS 5400 and which provide additional requirements. This publication supersedes the guidance given in the earlier documents P065, P066 and P084.

-The complementary publication to P289 Design guide for composite bridges above. Provides worked examples of composite bridge design to BS 5400, including the amendments to Part 3 issued in 2000. Three sets of calculations are presented. One is of a 20m span continuous bridge that is designed on the basis of compact sections. The second is a three span haunched bridge that is designed on the basis of non-compact sections. The third example covers the design of a deck slab. The examples are given in the form of calculation sheets with facing commentary pages. All the examples are updated versions of those previously given in publications P065, P066 and P084.

-This publication provides design guidance on a particular form of composite highway bridge, the ladder deck form. Ladder deck form has two main girders, spanning longitudinally, and multiple cross girders spanning between the main girders; the deck slab spans longitudinally between these cross girders. This particular configuration gives rise to design issues that differ from the multi girder form of construction covered by the two SCI publications Design Guide for Composite Highway Bridges (General Guidance and Worked Examples). This publication is complementary to the earlier publications.
Guidance is given on initial design of ladder deck bridges, covering the reasons for choosing this form, the selection of configuration and the initial sizing. Advice is given on the application of the design rules, according to BS 5400. Guidance on the design of cross girder connections and some aspects of detailing is also provided.
Three short worked examples of design calculations are included.

-This publication provides detailed guidance on best practice in an area of bridge design on which there has until now, been very little published advice.
The guide sets out a review of the particular requirements for carrying railway traffic and interfacing with railway infrastructure and, since construction issues are particularly acute for replacement bridges, describes the constraints and options for bridge construction. Typical forms of construction for short to medium span bridges are described and simplified cross sectional arrangements are illustrated. A key consideration for the selection of railway bridges is a safe and reliable structure that can be constructed and maintained with minimal disruption to railway passengers and traffic - steel railway bridges meet these requirements particularly well.
The guide explains that design of railway bridges in the UK is governed not only by BS 5400 but also by the comprehensive additional requirements of the railway authorities, notably Network Rail. Design procedures are described and detailed aspects of design for strength, for fatigue endurance and for deformation performance are discussed. A range of typical details is illustrated, with comments about the factors that need to be considered when selecting and designing them.

-Today, both durability and economic factors play a very important part in the choice of bridge
abutment type. Durability considerations are very important in providing long-term performance
of the bridge structure, both in the choice of structural form and in the design of construction
details. Economic considerations focus on the whole life cost and on the duration of
construction. This is particularly so with replacement bridges, where there is a significant cost
element for lane rentals for closures, and a more expensive design may make overall savings from
an earlier completion time. In addition, where land/space is limited in urban areas, the type and
method of construction are also important, because of the constraints being imposed. Steel sheet pile embedded retaining walls for bridge abutments can fulfil the criteria for economic bridge abutments. It is hoped that this guide will encourage designers and onstructors to consider a steel substructure more frequently during the conceptual and preliminary design phases of project, and thereby to take advantage of the potential to build more efficiently. The guide is written with reference to UK construction legislation, Department of Transport specifications, and both UK Codes of Practice and European Standards.

-Since 1996, the extent of integral bridge construction has grown significantly and preferred forms of construction and construction details have developed. This Technical Report presents an overview of the forms that have been most commonly chosen for bridges with composite decks and discusses the details and the reasons for their adoption.
It presents a brief summary of current practice, based on the experience of designers and constructors actively involved in the construction of integral steel bridges. The report identifies the three principal configurations that are most commonly chosen and presents data about the numbers and types of steel highway bridge that have been built in the period since 2000. For each of the three configurations, the form of construction of the end supports are described and illustrated, and the particular design and construction issues are discussed.
The effect of skew on the design of the end supports is also discussed, the junction with the road pavement is mentioned and the choices for intermediate supports are presented.

-This publication seeks to explain the suitability of steel-intensive integral bridges and how they can be designed and built. It describes the concepts and principles involved and illustrates ways in which the presently most common form of highway bridge, the composite deck bridge, can be
adapted to become an integral bridge. Opportunities to use steel elements in the bridge substructure, including steel piling for retaining wall abutments and columns, are examined.

-This publication provides a worked example for the design of a multi-span, fully-integral bridge
that utilises H-pile abutments, composite tubular pile column intermediate supports, and a composite plate girder deck. Calculations are provided for each design stage, together with a detailed commentary explaining the background to the methods employed and the parameters chosen. Computer-based numerical techniques have been used to enable full soil-structure
interaction to be considered in the analysis. At the abutments, a design is proposed for the fully- integral connection between the H-piles and the composite deck. Collision loading on the intermediate supports is considered, and two cross-head options are investigated.

-This publication offers design guidance to facilitate the use of steel pile abutments for a single-span integral bridge with retained heights of up to 9 m. It is based on findings of studies undertaken on integral bridges by the SCI since 1993. The worked example proposes a design method for a full moment connection between a steel superstructure and the sheet pile wall and covers the following areas: general arrangement; soil profile; ReWaRD stability analysis; wall and capping beam stiffness; loading; FREW model; WALLAP analyses; structural checks - retaining
wall; structural checks - deck; pile cap design.

-The purpose of this Technical Report is to suggest ways to encourage the use of full-thickness, full-width, precast deck slabs in highway bridges, installed on top of steel girders and made to act compositely in carrying live loads and superimposed dead loads.
The publication introduces the reader to precast deck construction for single span and continuous multi-span bridges. The report considers and compares the different types of precast deck configurations that have already been built or proposed and includes recent research information that supports the use of this form of construction. A recommendation is made as to the most appropriate form of precast deck construction, based on the supporting technical information that is currently available. It is noted, however, that client authorities may need test evidence before accepting this form of construction for any particular project.
A number of key aspects have to be addressed in the design and construction of efficient, safe and economic full-thickness precast concrete decks for steel composite bridges:
Sizing the precast deck units.
Seating and alignment of the precast units onto the steel girders.
Sealing of the concrete steel interface between deck and girders
Forming a composite bridge deck.
Forming an effective joint between precast deck units.
Formation of the edge beams.
Appendices include case studies and tests on full strength joints for precast concrete deck units.

-Presents the results of an independent survey into the performance of protective coatings
systems for bridge steelwork. Views and experiences were sought from agent authorities,
fabricators, maintenance painting contractors, and paint manufacturers, by questionnaire and by holding an informal colloquium. The responses confirmed the good performance being obtained with systems used in the past 20 years, and suggested that consideration should be given to accepting alternative systems that offer longer lives than the present systems. Proposals were given for changes that could be made by the Highways Agency in defining overall requirements
for maintenance work, and for the evaluation of Whole Life Cost in a way that recognises actual performance rather than conservative simple rules.
