The Structural Engineer, Volume 78, Issue 23, 2000
This paper describes the civil work involved in the demolition of Tsing Yi Power Station in Hong Kong, during 1998. The work included the use of explosives to safely demolish the five, up to 150m-tall, reinforced concrete chimneys. This was one of the first and largest uses of explosives in demolition in Hong Kong. Demolition methods adopted in Hong Kong and the UK are compared and contrasted. T.J. Dishman
Eighteen large-scale reinforced concrete columns, with concrete compressive strength (fcu) of 55.24N/mm² or 76.15N/mm², were tested under short-term loading. The effective-length-to-depth ratios Le/h) of the columns are 26.2,28.7 or 30.4, load-eccentricity-to-depth ratio (e/h) is 0.25 or 0.50, and steel ratio (p) is 3.35% or 5.24%. The experimental behaviour of the columns is presented and discussed. P.H. Chuang, S.K. Kong and Emeritus Professor F. K. Kong
The highly publicised closure of the London Millennium Footbridge owing to excessive lateral vibration at its opening on 10 June 2000 has highlighted a potentially critical loading effect not currently considered in international bridge design codes. The purpose of this update is to alert designers to the phenomenon, to disseminate information about it, and to identify what further research is necessary before definitive design rules can be developed.
