This fib Recommendation gives technical guidelines regarding design, testing, acceptance, installation, qualification, inspection and maintenance of stay cable systems using prestressing steels (strands, wires or bars) as tensile elements, which can be applied internationally. This Recommendation is applicable for cable-stayed bridges and other suspended structures such as roofs. It may also be used for hangers in arch structures and as suspension cables, as appropriate. This Recommendations has been formulated by an international working group comprising more than 20 experts from administrative authorities, universities, laboratories, owners, structural designers, suppliers of prestressing steels and stay cable suppliers. The text has been written to cover best construction practices around the world, and to provide material specifications that are considered to be the most advanced available at the time of preparing this text. For ease of use (for client, designer and cable supplier), the complex content has been arranged thematically according to the system components into chapters focusing on performance characteristics, requirements and acceptance criteria. Requirements and comments have been specified for all parties involved in design and construction in order to aim for a uniform and high quality and durability. The interfaces to the structural designer are highlighted. The essential subjects are: Design and detailing of stay cables including saddles and damping devices Durability requirements and corrosion protection systems Requirements for the materials Testing requirements for the stay cables Installation, tolerances, qualification of companies and personnel Inspection, maintenance and repair. This Recommendation does not cover the technology of stay cables whose tensile elements are ropes, locked-coil cables, etc. or which consist of composite materials. Nevertheless, in many cases the specified performance criteria may also be applicable to these systems, although numerical values given for the acceptance criteria may need to be adjusted. For these systems it has been difficult to provide multiple protective layers similar to those specified for stay cables made from prestressing steel and therefore, the quality of corrosion protection may not be equivalent. While extradosed cables have similarities with stay cables, generally agreed design and system acceptance criteria are not yet available and therefore, this type of cable is not covered.

Guidance on Protecting and Extending the Life of Suspension Bridges Suspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also an essential form of transportation infrastructure built across large bodies of water. Despite being expensive to build, they are economical structures for the lengths they span. They have evolved significantly from the basic concept dating back to 200 BC China through the first design for a bridge resembling a modern suspension bridge, attributed to Fausto Veranzio in 1595, to present-day span lengths close to two kilometers. Many of these bridges carry significant traffic and their upkeep is very important to maintain transportation mobility. They offer grace and functionality, yet are extremely complex to construct and maintain. Bridge owners spend a considerable amount of time and resources to ensure uninterrupted service, safety, and security for users. Inspection, evaluation, maintenance, and rehabilitation have evolved significantly. Modern materials and innovative design and construction practices have been integrated into these bridges to maintain durability and extended service life. Captures the Experience of More Than 20 Suspension Bridge Operators Inspection, Evaluation and Maintenance of Suspension Bridges is written by the bridge owners and practitioners who strive to cost-effectively manage these bridges. It is invaluable to everyone interested not only in suspension bridges but in the upkeep of any bridges—students, designers, maintenance personnel, contractors, and owners. Describes the evolution and trends in the operation and maintenance of cable supported bridges Contains the latest methods for evaluating cable supported bridge capacities and durability Presents suspension bridge security risk management aspects and Bayesian network-based methodology for risk evaluation This volume discusses state-of-the-art practice in suspension bridge inspection, evaluation, and rehabilitation methods used worldwide, described by the personnel directly involved with managing them. Its companion volume presents detailed case studies of specific bridges to give a comprehensive picture of how suspension bridges are maintained around the world.

"This study developed inspection guidelines to assist bridge owners in selecting the most appropriate nondestructive evaluation (NDE) method for assessing the condition of in-service post-tensioning and stay cable systems. These inspection guidelines describe NDE methods for different condition assessment including corrosion, section loss, breakage, grout conditions, voids, water infiltration, and tendon deterioration in the anchorage systems. The NDE methods are ground penetrating radar, infrared thermography, electrical capacitance tomography, magnetic flux leakage, magnetic main flux method, impact echo, ultrasonic tomography, ultrasonic echo, sonic/ultrasonic pulse velocity, low frequency ultrasound, sounding, visual testing, and electrochemical impedance spectroscopy. The material in this report will be of immediate interest to bridge owners and inspectors". -- https://trid.trb.org/view.aspx?id=1466278.

Effective maintenance of bridge structures comprises a broad spectrum of plans for repairs and services implemented to enable bridges to perform their intended function. These include in-depth inspection, fatigue analysis, design of mitigation measures and construction to avert component deterioration. Several incidents of in-service and under construction bridge failures have recently taken place. These dramatic failures emphasize the importance of risk-based inspections and analysis of real-life data to evaluate reliability of bridges. To effectuate benefits of reliability analysis in bridge maintenance, work on theoretical reliability must be equipped with practical analytical tools. Such an approach must underscore risk elements and identify processes to manage risk and avoid unexpected outcomes of failures and service disruption of bridges. The devastating earthquakes of February 6, 2023, in the southern region of Turkey near the northern border of Syria, which claimed tens of thousands of lives, caused enormous structural damage and staggering economic losses. These seismic events brought to focus on the vitality of instilling infrastructure routes that must accommodate emergency management plans to integrate the influx of medical and rescue response teams. The safe operation of bridges along these routes is indispensable for mobilization and deployment of rescue teams, medical personnel, humanitarian assistance, and the supply of food and water. The reliability of access routes and bridges is defined by their ability to adequately function as planned to effectuate emergency management plans, in the event of a similar seismic event, anywhere in the world. Risk-Based Strategies for Bridge Maintenance contains selected papers presented at the 11th New York City Bridge Conference (New York City, USA, 21-22 August 2023), and discusses issues of reliability, risk assessment, management, maintenance, inspection, monitoring, design, preservation, and rehabilitation of bridges. The book is aimed at bridge engineers.
