The frequent use of post-installed reinforcements to rehabilitate and strengthen existing buildings and other structures have made this technology increasingly important. The technology, which connects new structural components to existing concrete structures, offers flexibility in design and construction. The international market, however, has a paucity of guides for the design, installation, and quality control of post-installed reinforcements. Guide for Design, Installation, and Assessment of Post-Installed Reinforcements aims to address this gap by proposing an innovative approach to post-installed reinforcements combined with local design provisions, revealing the possibilities for post-installed reinforcements to designers, contractors, and building control bodies alike.
