Mr D. K. Doran (F) It has been my privilege for the past 7 years to chair the two Institution task groups working on this topic. One of the benefits of being Chairman is that one does not have to do too much work. What cannot be delegated, of course, is responsibility, and I accept that. Tonight I should like to pay public tribute to the hard work of the two task groups which have valiantly laboured to produce these reports, and in particular tonight’s speakers for putting together, in fairly short order, our papers for this evening. Mr. D.K. Doran
The Chairman What has been done with the building now that Expo has finished? I understood, at the beginning, thathe buildings were to be folded up and taken away and used elsewhere. What is the current situation?
There have been many situations in which flexural members - especially bridge girders -have been found to have less than the desired strength. A widely used method of providing additional strength has been the introduction of prestressing by means of external tendons'. External tendons are prestressing strands situated outside the original concrete section and are connected to the structure by anchorages and deviators. B.J. Sun
