Guide for the Design and Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures

TLDR
The Emerging Technology Series as mentioned in this paper is a series of information and recommendations based on available test data, technical reports, limited experience with field applications, and the opinions of committee members, with a focus on the development and appropriate use of new and emerging technologies.
Abstract
*Co-chairs of the subcommittee that prepared this document. Note: The committee acknowledges the contribution of associate member Paul Kelley. ACI encourages the development and appropriate use of new and emerging technologies through the publication of the Emerging Technology Series. This series presents information and recommendations based on available test data, technical reports, limited experience with field applications, and the opinions of committee members. The presented information and recommendations, and their basis, may be less fully developed and tested than those for more mature technologies. This report identifies areas in which information is believed to be less fully developed, and describes research needs. The professional using this document should understand the limitations of this document and exercise judgment as to the appropriate application of this emerging technology.
