Abstract

"While externally-bonded fiber-reinforced polymer (FRP) composites are commonly used for the strengthening of structurally deficient reinforced concrete (RC) members, the topic of anchoring FRP to concrete to achieve higher design strengths has not been addressed. Many innovative systems have been developed to anchor FRP to concrete, but the research involving these anchorage systems is not centralized and is therefore difficult to access. Additionally, systematic testing procedures for evaluating the strength of an anchorage system have not been widely used. To aid in the organization of anchorage system research and facilitate a better understanding of anchorage system behavior, a categorization system was developed based on the understood behavior of the FRP anchorage systems, as well as their potential applications. This new categorization system was used to discuss the applicability of anchorage testing procedures to various types of anchorage. Experimental research involving anchorage systems used for the emergency repair of severely damaged bridge columns was also performed. The anchorage systems included a novel anchorage system that was the focus of the experimental portion of this research. Results from the experimental program show that while the novel anchorage has promise for use in FRP strengthening applications, the assumed behavior of the novel anchorage was inconsistent with the observed behavior. Because detailed design procedures could not be developed using the experimental data, future testing of this anchorage system should be performed in the absence of the large number of variables that affected the anchorage's performance during the column tests"--Abstract, page iii.
