The Structural Engineer, Volume 60, Issue 11, 1982
That cranked beam. . . again Overall stability We hope that the problem presented by M. C. E. Lea in the September 1982 issue provoked some thought and perhaps even confusion. In his letter to us, Mr Lea demonstrated two ways to arrive at a solution. His first approach was an analysis by strain energy which is long and mathematical, so we do not publish it here. We are sure that you will be able to do that for yourselves (if you have not already done so), once his answer is available! His second approach, together with his own comments, we publish in full: Verulam
The formal corntnent of the Institution on the consultative document Private certification for building control, issued by the Department of the Environment, is set out below.

Mr E. H. Thorpe (M) (South West Water Authority): It has been my privilege to work alongside Mr Walmsley since 1974, during which time limit state design and BS 5337 were introduced and applied to the programme of investigation into the many alternative ways of designing service reservoirs and the considerations to be taken into account. From the paper you will have seen that, in one particular aspect, we have not adhered to BS 5337 and that is in our use of ‘option 2’ for the determination of thermal steel areas for reservoir roof flat slabs. Perhaps Mr Walmsley would like to make further comments on this point.
