The Structural Engineer, Volume 57, Issue 7, 1979
The authors have, for 'many years, been involved in leading multidisciplinary engineering groups, working on the design of buildings with other firms of architects and quantity surveyors. This paper reviews the experience gained by examining the different stages of the design process and commenting on the lessons learned by working in this way. This review is illustrated by referring to some relevant projects. The paper concludes by suggesting that much can be done to encourage effective interdisciplinary collaboration by means of training and by improving the ways in which the 'normal duties' of the building design professions relate to each other. J.N. Martin, R.F. Emmerson and J.S.A. Berry
Mr. M. G. Stevens: The layout and load capacity of a typical king pile is given in Fig 1.
I comment on the paper 'Structural behaviour of reinforced concrete columns in service'. I would make it clear that I make no claim 'to be competent to judge the quality of the authors' work and, as is my usual practice, I first read only the synopsis. This included the comment that the creep effects of load transfer from concrete to steel should be considered at the design stage. Being a design engineer, I concluded I ,must read the full paper. Having done so, I was not able to recognise any part of the contents that appeared to support this particular conclusion. There appeared to be no consideration of the effect on the ultimate capacity or serviceability of the column, which I understand to be the material criteria for design. There was a reference to the relationship between observed steel stresses and the CP 114 value of 'working stress', but I respectfully submit that the authors misunderstand this Code, as it is not actually based on working stresses but on factored ultimate stresses-a fundamentally different concept that makes the comparison meaningless.
