The Structural Engineer, Volume 75, Issue 21, 1997
The Building Act 1984, which generally came into force on 1 December 1984 in England and Wales, allowed provision to be made for the approval of persons to give a certificate that the proposed work, if carried out in accordance with the deposited plans, will comply with the Regulations. B.A. Cox
This paper establishes an up-to-date measure of the variability of the material and geometric properties of commercial quality structural steel. A comprehensive set of measurements (over 7000 samples) was obtained and collated. The large data set was suficient to evaluate the type of probability distribution characterising variability. The results provide the detailed statistical evidence essential for reliability analyses of the type needed to underpin the selection and calibration of new design rules for structural steel components. The statistical data reported are compared with the measures of variability assumed during the calibration of Eurocode 3 (EC3) partial safety factors; it is shown that some of these may safely be reduced. M.P. Byfield and Professor D.A. Nethercot
Mr J. K. Botterill (M) Further to the extensive correspondence in Verulam during 1995, I am still waiting for a revision, or at least guidance notes, giving a clearer and more complete set of safety factors for BS 8002 Earth-retaining structures, to enable engineers and technicians without specialist soil knowledge to design everyday retaining walls consistently.
