The Structural Engineer, Volume 55, Issue 4, 1977
We undertook in January to publish in our next issue a statement from the Librarian about the new classification system which has been introduced in the library and apologise that it is two issues later than was promised. However, here it now is : Since 1965 'catalogue entry slips' have been published at the back of each issue of the Journal, giving a single entry for each paper published. A UDC (Universal Decimal Classification) number has been assigned to each paper since that time (printed above the title of each paper in the text and on each 'slip'). Verulam
The development of dead load stresses in the columns of an eight-storey reinforced concrete structure during construction is reported. The in-situ steel and concrete stresses were measured respectively through acoustic gauges and a Carlson stress meter. Typical data on the development of steel strains are presented. The difficulties of interpreting the concrete stress meter readings are described. The influence of the construction process on the development of concrete stresses is shown. R.N. Swamy and M.M.A. Potter
The President: We have had the pleasure of listening to a most interesting paper. I am sure there is a considerable future for this line of research. I remember a few years ago being asked by Messrs. Stewart and Lloyds to advise on the possible uses of both thin walled plastic tube and very thin steel tube buried in the ground. I was not able to discover any references to research work in this field. The paper we have had before us tonight has not only given guidance with regard to the carrying capacity but has also provided interesting information about the mode of failure of the tube.
