Retrofitting of building structures, including maintenance, rehabilitation, and strengthening, is not only an important issue in urban construction and management, but also a frequent problem to structural engineers in property management disciplines. Based on the contributors’ hands-on experience, Retrofitting Design of Building Structures covers structural retrofitting practices, the basic principles of structural analysis and design, and various innovatively-used structural codes for the design, assessment, and retrofitting of building structures using newly-developed technologies worldwide.Beginning with the procedure of structural retrofitting, this book gradually introduces the significance of structural retrofitting; the inspection methods for structural materials, structural deformation, and damages; retrofitting design methods and construction requirements of various structural systems; and practical examples of structural retrofitting design and construction. In the introduction of various examples, it emphasizes not only conceptual design, but also constructional procedure design, so that a structural retrofitting design work should be completed by both structural analysis and detailed constructional measures. The book provides a complete resource for experienced professionals as well as teachers and students.
