The Structural Engineer, Volume 52, Issue 9, 1974
Mr. B. Rhodes: Mr. Longbottom has done less than justice to large diameter strand, by which I mean 28 mm (1 1/8 in) diameter strand. I know it is not used a lot, but this is really because of lack of effort on the part of the manufacturers and the system suppliers. 28 mm diameter strand has certain basic drawbacks, namely: 1. The shape of the load/extension curve 2. Relaxation losses at 6 per cent 3. Lower grip efficiencies 4. The tendency to fly open when cut 5. The 'banana' effect at the ends
Professor S. Mackey (F) : My main concern is to learn why, in Britain, limited records of wind and pressure measurements are being extrapolated to such a degree that if applied to Hong Kong conditions would render economic design of buildings impossible.
By any standards bomb damage is a messy business. Even when considered by the structural engineer back in his office and away from the debris and the broken glass, it is untidy and presents problems that are far different from those entailed in the design of new works. Peter S. Rhodes
