Though the steel portal frame is one of the simplest structural arrangements for covering a given area, the designer probably has to satisfy at least as many different structural criteria as for more complex structures. Present-day design of portal frames is reviewed in the light of recent research studies into certain aspects of the behaviour of portal frames, particularly the problem of stability of haunched rafters. Guidance is given for checking the lateral stability of such members. L.J. Morris
Dr. D. Tordoff (BCSA): We are all conscious of the fact that changes are taking place in design specifications and I should like to ask Mr Needham to comment on the changing philosophy of connection design with the introduction of limit state principles. Will a different design approach be required, and is there any research needed, or being undertaken currently, for a new design approach?
Aims of our Institution My Address coincides, in point of time, with the start of a new phase in engineering-the introduction of the Engineering Council. This Government-sponsored body is expected, in due course, with the agreement of CEI, to take over the granting of the title of ‘chartered engineer’. The Engineering Council will promote and develop the knowledge and best practice of engineering. Since we, in this Institution, have affirmed that our aim is ‘to promote the general advancement of the science and art of structural engineering’ then there can be no conflict in our respective aims. It is as well, however, to recall that whatever happens elsewhere, we have the sole right to qualify chartered structural engineers. Indeed, it appears to me important that in our pursuit of excellence in engineering, our members understand that we intend to continue to discharge this function with our accustomed vigour and energy. There is no doubt that our standards, as has been said before, are higher than those envisaged in the Finniston Report. We do not intend to lower those standards. T.N.W. Akroyd
The Presidential party arrived in Vancouver on Monday 31 August 1981 to be welcomed by Dr. Steve Faliszewski (F), Institution Representative in British Columbia. The following morning, Professor Horne and the Secretary visited the Civil Engineering Department of the University of British Columbia and were entertained at lunch by the Dean of the Faculty of Applied Sciences in the enviable Faculty Club overlooking the Frazer River. Later in the day Dr. Faliszewski arranged a dinner party at Grouse Mountain Lodge-a skyride above Vancouver Island. Professor and Mrs Horne met numbers of members, some of whom had travelled considerable distances, including Mr and Mrs David Bevan, Mr and Mrs Roy Metcalf, and Mr and Mrs David York.
When a house or some other form of property changes hands, the buyer usually commissions a survey of it; or, if a mortgage is negotiated, the Building Society will give instructions for a surveyor to establish value. Whoever undertakes a survey is legally responsible for what is said in the report to the client.
The role of Codes as an aid in achieving good construction is much in dispute. Should they be somewhere between recent research and standardised proven requirements, telling engineers what is good practice, or should they be precise documents that set out how the task should be handled? Assuming that such precision is even possible, is it in fact desirable, or will innovation and flair be stifled? Are they a guide to the knowledgeable or a safety net for the amateur? If precise in their demands, should such Codes be the means of meeting statutory requirements? J.G. Sunley and R.G. Taylor
Christmas test For students this is the time of year for Christmas assessments and, for qualified engineers, the time for riddles from Christmas crackers. Here is an assessment for you all! Please note the time allowed and check your answers. Verulam
