Some Properties of a Sphere Useful to Structural Engineers

Possibly, because it is under revision, we have not had many comments in the past on BS449. However, a reference to the forthcoming revision in the paper by Johnson and Smith (September 1975) has drawn the following from Mr. R. Taylor: It is interesting to note that in their paper concerning deflections of composite beams, Johnson and Smith, quoting from the forthcoming revised BS449, state that the final deflection of a beam below the level of supports should not exceed span/250, or for a cantilever length/l25. Since this particular limitation is from the appearance standpoint, the relative values quoted for a beam supported at each end and for a cantilever seem logical. Verulam

The present statutory control of building and engineering works in the United Kingdom varies greatly in terms of quality and efficiency. There are separate systems, for England and Wales, for Scotland, for Northern Ireland, and for the inner London area. The system proposed in this report will provide an integrated control structure independent of central or local government and therefore more readily adaptable to suit future changing needs.
