Preface
Structures made of building materials such as concrete are strengthened and protected, iron and steel are durable yet healthy. The most problematic types of signals are those exposed to the marine environment, mineral deposits on highways, industrial pollutants and, to a lesser extent, the natural environment. From an economic perspective, it is often quite feasible to repair a building, if possible, rather than demolish it and rebuild.
In the context of repair or improvement of concrete elements, the use of reinforced concrete has proven to be an effective, simple and economical way to improve performance. However, the disadvantages of using metal have encouraged the investigation of alternative ways to use reinforced polymer materials (FRP), which provide a non-destructive and versatile alternative; It can also be used on concrete.
The construction industry uses polymer materials for building maintenance and is showing interest in using FRP materials to maintain structural integrity or improve structural systems. Modern building materials can be combined with polymer brackets and/or bond angles to form plates, rods, pipes and other structural elements; the fibers are carbon, aramid or glass. When used as a structural material to repair or strengthen a polymer system, the composition should not float or bend during bonding.
When two different materials with common functions are to be used in a structure, designers need to understand the mechanical properties and function of the components, the connection methods, the operational and failure functions and the general analysis of the properties of these systems.
The book provides a detailed study using experimental tests and full-scale, theoretical and numerical tests on models for strengthening reinforced concrete elements with respect to the use of fiber-ferro-polymer composite plates covering short and long-term performance. Additionally, in Chapter 2, ‘Overview of materials and techniques for joining slabs’, this book reviews previous research and field studies carried out as far back as on the strengthening of reinforced concrete beams and RC beams using steel fasteners and discusses its pros and cons . . . Using two different materials: metals and components. The connection of the cutting plates is also not covered in this section.
Chapter 11 of the book provides case studies of parts modified or reinforced using carbon fiber/polymer matrix materials for composite structural parts. The case history also includes improving steel reinforcement and respecting timber systems.
The information in this book is derived primarily from material prepared or presented by a consortium that studies and analyzes the technology of joining plates for the improvement of structural components using carbon fiber/polymer materials. Research tests and trials were carried out within the scope of ROBUST (Strengthening of Bridges Using Polymeric Composite Materials), one of several projects in the DTI-LINK Structural Composites Program me.
The authors would like to emphasize that their aim was to obtain the most comprehensive research data from this study. The ongoing study of using this information in producing/preparing designs should be left to practicing engineers and should not be considered part of the scope of the book. This type of information has been and continues to be developed in a business environment that continues to use software development technology.
The industry members in the consortium include Mouchel Consulting Ltd (principal partner), Royal Military College of Science and Concrete Repair Ltd (main contractor partner), Oxfordshire County Council, Balvac Whitley Moran Ltd, Tec build Composites Ltd (now Fiber force Rein-force Composites Ltd). is.), Vertex (UK) Ltd, James Quinn Associates Ltd and Sika Ltd. Academic partners University of Surrey and Oxford Brookes University have received support of £from the Engineering and Physical Sciences Research Council (EPSRC) under the DTI-LINK programmer. Further research was also carried out at Oxford Brookes University, funded by this university, and at the University of Surrey, funded by the EPSRC, as well as a university-funded study and a further study.
The writing of the various chapters in this book has been the responsibility of authors who are not named as the authors of these chapters and who have obtained their information from many sources but are largely dependent on the cooperation of researchers working on this subject. Project business and industrial members of the ROBUST consortium; This invaluable help is greatly appreciated.
