Technical Abstract
A research project No. 91/15 entitled "Strengthening and/or repair of existing reinforced concrete columns" funded by the Earthquake Commission, was commenced at the University of Canterbury in 1991. EQC granted $32,000 for the project. This project is the second phase of the project "Development of methods for the strengthening and/or repair of existing reinforced concrete columns" which was funded by EQC in 1989. This second stage of the project was supervised by Professor R Park and Dr H Tanaka. A master of engineering student, Mr Shigeru Hakuto from Japan, conducted the experimental work during 1991 and 1992.
The second phase of the project has involved a literature review of recent techniques for strengthening reinforced concrete frames including the beam-column joint region and seismic load tests conducted on two full scale beam-column joint units strengthening by jacketing.
