SYNOPSIS

 

Guidelines presented were originally published in Japanese in JSCE's Concrete Library No.95 in 1999 as the work of the Working Group on Retrofit Design of Concrete Structures under the Subcommittee on Revision of Standard Specification of JSCE's Concrete Committee. They are the first guidelines for retrofit of concrete structures issued by JSCE. The guidelines prepared with performance-based concept provide flow chart for retrofitting process, inspection and verification of performances of existing structures, selection of retrofitting methods, specification of retrofitting materials, verification of performances of retrofitted structures, and detailing and execution for retrofitting. Although only external cable method, bonding and jacketing method and overlaying and jacketing method are covered in the guidelines, the main concept is applicable to any retrofitting method. The original Japanese version of the guidelines is accompanied by manuals and design examples of each retrofitting method covered by the guidelines.

 

Keywords: retrofit of concrete structures, external cable method, steel plate bonding method, fiber-reinforced plastic bonding method, steel plate jacketing method, fiber-reinforced plastic jacketing construction method, surface overlaying method, Reinforced concrete jacketing method
