Advanced composite materials for bridge structures are recognized as a promising alternative to conventional construction materials such as steel. After an introductory overview and an assessment of the characteristics of bonds between composites and quasi-brittle structures, Advanced Composites in Bridge Construction and Repair reviews the use of advanced composites in the design and construction of bridges, including damage identification and the use of large rupture strain fiber-reinforced polymer (FRP) composites. The second part of the book presents key applications of FRP composites in bridge construction and repair, including the use of all-composite superstructures for accelerated bridge construction, engineered cementitious composites for bridge decks, carbon fiber-reinforced polymer composites for cable-stayed bridges and for repair of deteriorated bridge substructures, and finally the use of FRP composites in the sustainable replacement of ageing bridge superstructures. Advanced Composites in Bridge Construction and Repair is a technical guide for engineering professionals requiring an understanding of the use of composite materials in bridge construction. - Reviews key applications of fiber-reinforced polymer (FRP) composites in bridge construction and repair - Summarizes key recent research in the suitability of advanced composite materials for bridge structures as an alternative to conventional construction materials

The objective of this research project is to outline methodologies for using Fiber Reinforced Polymer (FRP) composites to strengthen and rehabilitate reinforced concrete bridge elements. Infrastructure deterioration and bridge strengthening techniques using FRP materials are discussed as background. Properties and classifications of different reinforcing fibers and resin matrices are provided, along with the mechanical properties of the FRP composites. Basic concepts and design principles for composite FRP materials are introduced, and topics such as manufacturing processes, anisotropic elasticity, strength of anisotropic materials, and micro-mechanics are presented. Techniques and concepts for strengthening concrete beams with FRP composites are discussed, as are flexural and shear strengthening design and construction methodologies. The worldwide research experience in the behavior of FRP strengthened beams under various conditions are summarized. External reinforcement of concrete columns using FRP materials is examined. Theoretical background, factors influencing the performance of FRP wrapped columns, and various case studies are presented. Design methodologies and examples supplement the case studies for both beams and columns. Most FRP material systems available on the market today are summarized and evaluated. Construction and durability requirements of the retrofitted systems are presented. Reliability assessment, condition evaluation methods, and factors influencing the strengthening quality are included. The various steps of the construction process, such as selection of a composite strengthening system, concrete surface preparation, and bond between FRP and concrete are summarized. Quality control, environmental durability of FRP composites, and cost effectiveness are presented.

Rising awareness of and increased attention to sexual harassment has resulted in momentum to implement sexual harassment prevention efforts in higher education institutions. Work on preventing sexual harassment is an area that has recently garnered a lot of attention, especially around education and programs that go beyond the standard anti-sexual harassment trainings often used to comply with legal requirements. On April 20-21, 2021, the National Academies of Sciences, Engineering, and Medicine hosted the workshop Developing Evaluation Metrics for Sexual Harassment Prevention Efforts. The workshop explored approaches and strategies for evaluating and measuring the effectiveness of sexual harassment interventions being implemented at higher education institutions and research and training sites, in order to assist institutions in transforming promising ideas into evidence-based best practices. Workshop participants also addressed methods, metrics, and measures that could be used to evaluate sexual harassment prevention efforts that lead to change in the organizational climate and culture and/or a change in behavior among community members. This publication summarizes the presentations and discussion of the workshop.

The major expansion of transport networks in the twentieth century has been accompanied by extensive bridge construction. At the end of the century, the field of bridge engineering continues to grow and develop. Recent years have seen the construction of revolutionary new bridges, advances in materials and construction techniques and the development of international codes and standards aimed at producing more durable and reliable structures.

Following the success of ACIC 2002, this is the 2nd International Conference focusing on the application and further exploitation of advanced composites in construction held at the University of Surrey in April 2004. With over 100 delegates the conference brought together practicing engineers, asset managers, researchers and representatives of regulatory bodies to promote the active exchange of scientific and technical information on the rapidly changing scene of advanced composites in construction. The aim of the conference was to encourage the presentation of new concepts, techniques and case studies, which will lead to greater exploitation of advanced polymer composites and FRP materials for the civil engineering infrastructure, rehabilitation and renewal.

The global response to COVID-19 has demonstrated the importance of vigilance and preparedness for infectious diseases, particularly influenza. There is a need for more effective influenza vaccines and modern manufacturing technologies that are adaptable and scalable to meet demand during a pandemic. The rapid development of COVID-19 vaccines has demonstrated what is possible with extensive data sharing, researchers who have the necessary resources and novel technologies to conduct and apply their research, rolling review by regulators, and public-private partnerships. As demonstrated throughout the response to COVID-19, the process of research and development of novel vaccines can be significantly optimized when stakeholders are provided with the resources and technologies needed to support their response. Vaccine Research and Development to Advance Pandemic and Seasonal Influenza Preparedness and Response focuses on how to leverage the knowledge gained from the COVID-19 pandemic to optimize vaccine research and development (R&D) to support the prevention and control of seasonal and pandemic influenza. The committee's findings address four dimensions of vaccine R&D: (1) basic and translational science, (2) clinical science, (3) manufacturing science, and (4) regulatory science.
