- Synopsis
- Technology for the seismic retrofit of RC structures with post-installed plate-anchored shear reinforcement has steadily built up a track record since first being put into practical use in 2006. As the number of construction projects using this technology has been increasing, various improvements to existing technology and development of new technology have been achieved to meet an array of needs such as extension of the diameter range of applicable reinforcement, size modification of end plates to improve constructability, and application to deep beams. This paper describes the state of development of technology for the seismic retrofit of RC structures with post-installed plate-anchored shear reinforcement.
