The Structural Engineer, Volume 48, Issue 3, 1970
Long-term reform of building legislation 5. The Institutions do not propose to argue here the adequacy of the general procedure for building regulation laid down under the Public Health Acts. At another time they will be glad to make suggestions for the amendment of this legislation, but those suggestions must be related to the date when revised legislation is likely to be brought into operation, and must be framed with knowledge of the extent of local government reform and of the resources available.
Western Avenue Extension is a 4 km (2 1/2 mile) elevated road to near Motorway standards, currently under construction in West London. D.J. Lee
The general theory of beams curved in plan with torsional restraint at the supports is explained, with particular reference to prestress loading. It is proved that the torsional moments due to prestress loading are solely dependent on the support bending moments, and the conditions of concordancy are formulated for a circularly curved beam. It is suggested that for most practical cases the support bending moments in circularly curved beams can be calculated to sufficient accuracy assuming the beam is straight, and the order of accuracy is given. A similar approximation can also be made when analysing the effects of loads other than prestress. R.J. Garrett and R.A. Cochrane
