The Structural Engineer, Volume 53, Issue 9, 1975
Sir Alfred Pugsley (F) : I will just devote a few minutes, by way of introduction, to the place of history in the teaching of structural engineering.
Mr. P. B. Ronan: I would like to ask the authors if in retrospect they felt that the site investigation, in particular for a building of this magnitude, was adequate with particular reference to the two boreholes which were put down to give information about groundwater?
The authors have presented an interesting method for the rapid estimation of maximum bending moments in decks of suspension bridges. Their approximate analysis draws to a logical conclusion the more general method described by Bowen and Charlton (reference 3 of the paper). It is clear that the use of symmetry and antisymmetry offers a considerable computational advantage :two sets of three linear simultaneous equations are solved far more quickly than one set of six. F. Van der Woude, M.S. Gregory and H.I.A. Hegab
