This paper describes tests that have been carried out to determine the long-term deformation characteristics of Lytag lightweightaggregate concrete, in axial compression and deflection; comparisons are made with gravel concretes made from London-area aggregates. Professor R.H. Evans and W.S. Paterson
Dr. Le-Wu Lu (Research Associate-Professor of Civil Engineering, Lehigh University, Bethlehem, Pennsylvania) writes:- 'The authors are to be congratulated for contributing an interesting paper in an area which has attracted considerable attention in recent years. The use of computers in elastic-plastic analysis provides not only the potential of dealing with highly complex structures but also the capability of inclusion of many so-called "secondary effects". The program developed in the paper has attempted to include almost all the major secondary effects, except, as the authors noted, the following two:- (l) the effect of reduction of plastic moment (2) the spread of plastic zones in the members.
In the past few years the first Ordinary Meeting of the New Year has been given over to a discussion or debate on a theme of topical interest to structural engineers. Against the background of the much-publicized structural collapses of 1966 the meeting on Thursday 12 January at 6 o’clock to debate the motion ‘ That structural design is best carried out in professional offices ’ will provide an opportunity for airing members’ views on these events.
