A study is presented on vibrations of a long-span lightweight floor. The floor was analysed using various different methods to see whether it would have acceptable vibration characteristics in service. The vibration characteristics were then evaluated experimentally for the floor in its bare and finished states. The site evaluation included qualitative tests to assess human reaction to vibrations induced in the floor and quantitative tests to measure the characteristics of the floor. K.P. Osborne and B.R. Ellis

Results are given of 35 push tests using through-deck welded studs, three types of profiled steel sheeting, and shot-fired pins, with normal density and lightweight concrete. Maximum resistances are compared with the predictions of draft BS 5950: ‘Part 3.1’, draft Eurocode 4, and two reduction formulae for the effects of rib geometry. J.T. Mottram and Professor R.P. Johnson

One recent event, which (unfortunately) has received scant publicity, is the publication by the DTI of the report of the study teams on professional liability. The DTI called the report the ‘Likierman Report’, because Professor Andrew Likierman was Chairman of the steering group. There were three separate study teams, one for construction professionals apart from surveyors, one for auditors, and one for surveyors. J.J. Ward
