Auckland Town Hall, one of New Zealand's premier heritage buildings, was constructed around 1911 to provide Auckland with a world class concert venue and Civic Centre. Constructed of unreinforced masonry the building does not meet with today's seismic protection standards, particularly as a place of assembly. The owner of the building, Auckland City Council, determined that the building should be strengthened as part of an overall restoration programme. This paper describes the standards of strengthening adopted, the analysis and the strengthening systems utilised and is presented and published with the courtesy of Auckland City Council.
