Discussion on Lightweight Underground Structures by P.S. Bulson

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.

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.
