Evaluates the effects of different retrofit applications on the global response of short-spanned reinforced concrete bridges. Retrofitting methods addressed include steel jacketing of columns, foundation, and abutment retrofit.
This book presents the fundamentals of strengthening and retrofitting approaches, solutions and technologies for existing structures. It addresses in detail specific techniques for the strengthening of traditional constructions, reinforced concrete buildings, bridges and their foundations. Finally, it discusses issues related to standards and economic decision support tools for retrofitting.
In November 1999, bonded Fiber-Reinforced Polymer (FRP) laminates were used to strengthen a single span, reinforced concrete T-beam bridge in New York State. The laminate system was installed to strengthen the structure in flexure and shear, and to contain observed freeze-thaw cracking. The bridge was then instrumented and load tested before and after installation of the laminates, to evaluate effectiveness of the strengthening FRP system. In November 2001, the load test was repeated to monitor in-service performance of the system. The test results indicated that the quality of bond between the laminates and concrete, and effectiveness of the system have not deteriorated after two years of service. Further inspection using an Infrared thermography camera did not show any significant delamination in the system, in agreement with the test results.
Advanced Fibre-reinforced Polymer (FRP) Composites for Structural Applications, Second Edition provides updates on new research that has been carried out on the use of FRP composites for structural applications. These include the further development of advanced FRP composites materials that achieve lighter and stronger FRP composites, how to enhance FRP integrated behavior through matrix modification, along with information on pretension treatments and intelligence technology. The development of new technology such as automated manufacturing and processing of fiber-reinforced polymer (FRP) composites have played a significant role in optimizing fabrication processing and matrix formation. In this new edition, all chapters have been brought fully up-to-date to take on the key aspects mentioned above. The book's chapters cover all areas relevant to advanced FRP composites, from the material itself, its manufacturing, properties, testing and applications in structural and civil engineering. Applications span from civil engineering, to buildings and the energy industry. - Covers all areas relevant to advanced FRP composites, from the material itself, its manufacturing, properties, testing and applications in structural engineering - Features new manufacturing techniques, such as automated fiber placement and 3D printing of composites - Includes various applications, such as prestressed-FRP, FRP made of short fibers, continuous structural health monitoring using advanced optical fiber Bragg grating (FBG), durability of FRP-strengthened structures, and the application of carbon nano-tubes or platelets for enhancing durability of FRP-bonded structures
Relevant advances have been accomplished by the scientific community and engineering profession in the design, assessment, monitoring, maintenance, and management of sustainable and resilient bridge structures and infrastructures. These advances have been presented and discussed at The Sixth International Conference on Bridge Maintenance, Safety And Management (IABMAS 2012), held in Stresa, Italy, from 8 to 11 July 2012 (http://www.iabmas2012.org). IABMAS 2012 has been organised on behalf of the International Association for Bridge Maintenance And Safety (IABMAS) under the auspices of Politecnico di Milano. This book collects the extended versions of selected papers presented at IABMAS 2012 and invited papers originally published in a Special Issue of Structure and Infrastructure Engineering. These papers provide significant contributions to the process of making more rational decisions in bridge design, assessment, monitoring and maintenance. The editors would like to thank the authors for their contributions and hope that this collection of papers will represent a valuable reference for scientific research and engineering applications in the fields of design, assessment, monitoring, and maintenance of bridges and infrastructure networks.
Civil engineering is a profession that has been going on since the existence of humanity, from the past to the present, with a very wide scope divided into many branches of science. Not only the construction of structures, but also the retrofitting of existing structures has a very large place in the field of civil engineering. It is a fact that structures have an economic life depending on time. In addition, structures can lose their initial performance levels by being damaged due to natural disasters and environmental vibrations. In such cases, retrofit is required to restore the structure to its former performance. In historical structures, retrofit and restoration are also carried out to carry the historical heritage into the future. There are many different retrofit methods in terms of the purpose of use of the structure, earthquake, climate, cost, and architectural and historical texture. In addition, with the developing technology, retrofit methods are becoming more diverse and innovative methods are being added. Therefore, in order to get the maximum benefit from the retrofit method to be applied, it is of vital importance in the selection of the method to have done a lot of theoretical and experimental studies. The aim of this book is to shed light on the traditional and innovative techniques by separately and analytically examining the modal behavior of different types of structures retrofitted with different retrofitting techniques, and to valuable civil engineers and researchers. It is also aimed that the book will contribute to the education of undergraduate and graduate students in this field and guide them for future studies.
Bridge Maintenance, Safety, Management, Resilience and Sustainability contains the lectures and papers presented at The Sixth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2012), held in Stresa, Lake Maggiore, Italy, 8-12 July, 2012.
