The Structural Engineer, Volume 54, Issue 1, 1976
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. K.O. Kemp and J.G.A. Croll
The Cruachan Viaduct, carrying the Tyndrum-Oban trunk road A85 along the north shore of Loch Awe, was strengthened during the 1930s, but became inadequate for present-day traffic and a further major construction has recently been completed. E.H. Cooley
For some years, research has been carried out at the Cement and Concrete Association to study the relative structural merits of different reinforcement arrangements for certain common situations in reinforced concrete structures. This work was started partly because a few failures had occurred in practice and partly because there was a lack of basic data on how detailing affected strength. Early projects were therefore concerned with specific areas where problems had been experienced either in practice or in previous research projects and were aimed at determining the optimum steel arrangement purely in terms of strength. Topics covered at this stage included half-joints, flexural corners and compression splices in columns; the structural efficiencies of these were reported in a previous paper presented to this Institution'.
