A description is given of a system of interconnected beams representing a right simply supported multiple web cellular deck with no intermediate diaphragms, followed by an outline of a method of analysing the response of such a system to any externally applied loading. A short computer program using this method of analysis is described.
Results produced by this program are compared with experimental results of a model test and show agreement to within a few per cent. Finally it is shown how this theory was applied to the design of the New Cattle Market Bridge now under construction which when completed will carry the new Derby Inner Ring Road over the River Derwent.
This paper was prepared as part of the work of the Environmental Wind Committee of the Institution, and the author was assisted by other members of the Committee and by the representatives of the Institution in many countries, as well as by the national standards organizations concerned.
In 1969, a study was made of the results of tests on eighty steel-concrete composite beams in which longitudinal shear stress was high, and a new design method for transverse reinforcement in the slab was deduced. This gave a more uniform margin of safety than the method of CP 117 Part 1: 1965, and showed that the amount of reinforcement could be reduced by about 35 per cent.
