Emeritus Professor A. L. L. Baker (F) who from 1945-1973 was Professor of Concrete Structures and Technology at Imperial College, London, writes: The Report of the BRAC Sub-committee on high alumina cement concrete in buildings (The Structural Engineer, October 1975, p. 431 ) deals with a very complicated problem. May I comment and enquire if the following interpretation of the recommendation for calculating the ultimate resistance moment of an X-beam is correct.
We have read this paper with interest and its contents have prompted us to express the following opinion on structural analysis in general.

Effects of geometric imperfections in the form of the meridians of hyperboloidal cooling towers are re-assessed. It is shown that even moderate imperfections induce hoop stresses in the vicinity of the imperfection that are of the same order of magnitude as the meridional stresses that would occur in this same area of the perfect shell.
