This book focuses on the use of glass fibre reinforced polymer (GFRP) components in bridge construction and rehabilitation. It presents results of the most recent research, describing and illustrating the state-of-the-art design recommendations. The first part provides an overview of the most important features related to properties, analysis and design of GFRP pultruded components used in bridges; the second part presents several detailed case studies. This text is aimed at structural engineers in general and bridge designers in particular.It can also be used as a reference for advanced courses and by bridge authorities.
