Partial safety factors (y-factors) first appeared as a coherent system for dealing with the uncertainties involved in structural design 30 years ago. For nearly a quarter of a century they have been a feature of at least some design Codes in the UK. They are now used for most main UK design Codes and many European Codes and are the approach adopted for the Eurocodes. Professor A.W. Beeby
Though some engineers object, most modern structural Codes or design standards use partial safety factors, i.e. y-factors. With certain exceptions, there are generally two y-factors - yf for loads and ym for resistances. J.C. Taylor
The Structural Engineer - what should be in it? The nature of the contents of the Institution’s journal has been discussed frequently in Verulam - e.g. reference to the journal for 18 August 1992 will reveal quite extensive correspondence on whether the technical papers are ‘too academic and on the production of ‘practical’ papers. Darryl Blackwood, of Manchester, expresses a desire for an even wider range of articles and features than at present appears: The image of the profession has been a source of concern of late. One of the vehicles which promotes the image of the structural engineer is The Structural Engineer. Verulam
