Often slabs subjected to flexure are stiffened by edge beams having a neutral plane which does not coincide with that of the slab itself. This is frequent in bridges.
Dr. I. Fells (University of Newcastle-upon-Tyne): ‘First let me say that I am relieved by the confidence of our two speakers. Clearly, they are reasonably happy about the relief of the explosions. I wonder, however, if I might put on a hat that I am unaccustomed to wear, and that is one of pessimism.'
Mr. V. L. Cox: ‘A thing that worries me about materials or manufactured components and not the heavy items which seem to be required for your particular designs, is that if you look at the joints, you get down to a work size of 590 mm plus or minus two millimetres. This you have developed through your designing and through the requirements of the architect. If you look at the booklet that you have now, you will see that sheet sizes are, in fact, 600 mm wide. The whole idea of dimensional co- ordination is that you can use standard products and immediately you prove that 600 mm is not a necessary size. In fact it is too big and it has, therefore, to be cut and that involves additional expense. This does not relate to precast concrete and similar components, but it does relate to a large number of light panels. So we have had an argument for dimensional co-ordination and you have successfully proved that it is nonsense as far as the manufacture of sheets is concerned. This, I do not believe to be true, but it does present a series of rather worrying possibilities for the manufacture of sheets and for the manufacture of a number of lightweight cladding components. I am not putting a question because I do not think there is a question. It is just a statement of fact.’
