The Structural Engineer, Volume 47, Issue 11, 1969
The rebuilding of the Stock Exchange in London presents an interesting problem in design and in construction. The need was to produce a building of the highest possible standard architecturally which would not only satisfy the complex requirements of the Stock Exchange as a market but which would also be compatible with the contemporary City scene. At the same time the work had to be carried out without disrupting the operation of the Stock Exchange, and without risking damage to the Central Line tubes which run close alongside the site. This paper describes the first stage of the rebuilding and in particular the special construction of the foundations and also the loadbearing precast concrete exterior of the 27-storey-high tower which determines its architectural character. Peter Dunican and John Martin
Improved compaction, improved adhesion of cement matrix to aggregate particles and application of triaxial stress are seen as the main methods of improving concrete compressive strength. A.J. Harris
The paper presents a new approach to the analysis of bridge decks having a cellular transverse cross-section. It uses a modified finite element technique and solutions are obtained by fully-automatic computer program. Only the major stress-carrying modes are represented and a considerable saving in the number of simultaneous equations to be solved is achieved. The degree of accuracy obtained is assessed by comparisons with empirical values and the programs are used to investigate the effect of distortional stiffness on stresses. Professor F. Sawko and R.J.
