Without doubt, active corrosion protection of prestressing steels by cement grout can be one of the most economic and durable solutions, if properly executed. Numerous other corrosion protection systems which fulfill requirements such as controllability and exchangeability are available. This state-of-the-art report, prepared by a task group and approved by fib Commission 9 Reinforcing and prestressing materials and systems, concentrates exclusively on factory applied corrosion protection that can be produced in controlled processes which should assure a better quality than corrosion protection applied on site. The report is addressed to designers and installers (executing persons) attempting to inform them about the various possibilities for industrially applied corrosion protection and to provide the necessary knowledge for their application.

Cable-supported bridges are known for their visual elegance, aesthetic appeal and ability to link long spans. The extent of issues of concern associated with these structures is commensurate with their size and vast scale. Significant advances in the technology of assessment, design, construction and maintenance of cable-supported bridges have been achieved in the past few years, due to increasing awareness, collaboration and information exchange.This book contains selected papers on cable-supported bridges as presented at the 5th International Cable-Supported Bridge Operators' Conference, held in New York City on August 28-29, 2006. It includes papers by leading international bridge engineers. Presenting state-of-the-art material, the book is an authoritative account on the developments in the field, this volume forms essential reading to anyone working on cable-supported bridges. Advances in Cable-Supported Bridges .

The Model Code for Concrete Structures is intended to serve as a basis for future codes. It takes into account new developments with respect to concrete structures, the structural material concrete and new ideas for the requirements to be formulated for structures in order to achieve optimum behaviour according to new insights and ideas. It is also intended as a source of information for updating existing codes or developing new codes for concrete structures. At the same time, the Model Code is intended as an operational document for normal design situations and structures.

Construction projects are undertaken to meet a variety of business, service and aspirational objectives and needs. The success of a building or an element of infrastructure depends on how well it meets the owner's needs and interests or those of the users. Recent changes in owner attitudes to construction are reflected in an increasing interest in through-life costs, i.e. not only the capital costs of construction but also the operational costs associated with a structure's functional performance for a defined life span. The owner can greatly improve the likelihood of achieving the value they seek from the facility by being intimately and effectively involved in the definition of performance requirements at the start of the construction procurement process. The objective of fib Bulletin 44 is to provide guidance to owners of concrete structures on: the management of their concrete structures (buildings and infrastructure) as part of their business goals or the service objectives of their organization; best practice in the management of concrete structures; their responsibilities with respect to the management of their concrete structures; the wider context and issues of service life design; information and direction needed by the supporting professional team of architects, engineers, specifiers, contractors and others. This Guide also provides background information on topics such as deterioration processes and technical procedures used for the management of concrete structures, including reference to international standards for the protection and repair of concrete structures. These activities are illustrated by application examples/case histories and by a section addressing frequently asked questions. A brief review is made of some potential future developments.

The aim of this state-of-art report is to present current practices for use of precast and prestressed concrete in countries in seismic regions, to recommend good practice, and to discuss current developments. The report has been drafted by 30 contributors from nine different countries. This state-of-art report covers: state of the practice in various countries; advantages and disadvantages of incorporating precast reinforced and prestressed concrete in construction; lessons learned from previous earthquakes; construction concepts; design approaches; primary lateral load resisting systems (precast and prestressed concrete frame systems and structural walls including dual systems) diaphragms of precast and prestressed concrete floor units; modelling and analytical methods; gravity load resisting systems; foundations; and miscellaneous elements (shells, folded plates, stairs and architectural cladding panels). Design equations are reported where necessary, but the emphasis is on principles. Ordinary cast-in-place reinforced concrete is not considered in this report. This fib state-of-the-art report is intended to assist designers and constructors to provide safe and economical applications of structural precast concrete and at the same time to allow innovation in design and construction to continue. This Bulletin N° 27 was approved as an fib state-of-art report in autumn 2002 byfib Commission 7, Seismic design.
