The Strengthening of High-Rise Domestic and Industrial Buildings in Hong Kong

The Hong Kong Housing Authority is responsible for housing alrnost 3M people in over 1500 multistorey reinforced-concrete buildings. It is also responsible for the construction and maintenance of a number of 'flatted factories' that provide employment for public-housing tenants. In the mid-1980s, deficiencies in concrete strength, giving rise to serious concerns over structural adequacy, came to light in a number of domestic and industrial buildings which had been constructed during the late 1960s and early 1970s. This paper describes how these deficiencies were remedied by strengthening techniques developed against a background of social considerations and practical constraints. P.R. Ainsworth, R. Crane, G.G. Payne and R.A.M. Watkins
