The Structural Engineer, Volume 67, Issue 21, 1989
This President was torn between giving a ‘state of the art’ report on the health and development of the profession and of the Institution-our successes and our failures-or a statement on the ‘art we profess’. On the one hand, there is the danger of merely repeating, with some updating, the excellent reports that have been given by Past Presidents, and on the other there is the possible danger of indulging oneself, of ‘fiddling while Rome burns’. Experience would suggest that the art of pursuing one’s own policies while appearing to compromise is essential to the survival of any President. This I hope to achieve. J.H. Armstrong
The present state of specifications or recommendations governing the static design of welded structural hollow section (SHS) trusses and joints in various countries is reviewed, along with the calibration or adjustments made to suit particular Code formats. Recent international trends in the properties of manufactured tubes are described, and the impact these have on joint design is discussed. It is shown that recalibration of Eurocode 3 Appendix 6B proposals is warranted, prior to their adoption in the UK and elsewhere, and microcomputer-based design aids need to be subsequently produced for effective implementation. Professor J.A. Packer and G. Davies
The bulk of defects occur in the weathershield, and therefore the cladding, of buildings. Unless such cladding was also loadbearing, it has not traditionally been the responsibility of the engineer. In this age of specialisation, architects are less likely to be structurally qualified to deal with the secondary stresses which inevitably arise in the weathershield. Furthermore, the pattern of construction has changed, so that more engineering input is necessary.
