I think that the general issues raised by the feature are important not only for reinforced concrete construction but also for the future of the whole of British industry. Dr. Beeby’s main plea, I think, is for ‘realistic simplicity’, and I support this completely. Mr. Dennis Cox
This paper describes research on dynamic behaviour of conveyances and mineshaft steelwork. A description is given of the system used for measuring and analysing accelerations and wheel loads in 13 shafts, as well as the simplified theoretical model developed for predicting this behaviour. Results are given of both the measurements and the theoretical predictions, and the relevance of different design parameters is discussed. A tentative design formulation is proposed which includes the most important variables for shafts where resonance does not occur. Factors influencing dynamic magnification are also discussed. G.J. Krige, Professor A.R. Kemp, B. Alport and M. Fotopoulos
Buckling is usually associated with slender structures of stiff materials, such as steel and aluminium. This paper aim to show that it occurs, also, in foundation engineering and soil mechanics. Foundations and soil samples of relatively robust dimensions can be vulnerable to buckling when deformations are large, i.e. when the stiffness of the soil is low. E.C. Hambly
