Mr. K. F. Simm (of Freeman Fox & Partners) writes: ' The computer program described by the author greatly simplifies the analysis of reinforced concrete columns subject to bi-axial bending. It has been used in my office for some time and the data preparation is very much easier than the laborious hand calculation involved in Saville's method. '
Mr. Brian Scruby (Chairman): ‘ A point that occurred to me when reading your paper was that when I went to America a few years ago I saw some buildings which I thought were rather typical of the industrial side of American building and which seemed to be designed for a specific period of time. I wonder if you would say something about durability and its particular reference to the time factor? '
A method is presented in which the differences in stay tensions necessary to maintain equilibrium in a mast subjected to wind loading are related to the actual tensions developed in the stays as a result of changes in length of the stay chords caused by a displacement of the mast from an initial position.

As progress towards the change to metric gathers speed and new metric versions of the various structural Codes of Practice are published, there is a great deal of discussion about the metric units adopted to express force, stress and loading.
As most of the piers of viaducts act as cantilevers for horizontal loads at top, requiring greater rigidity at base along longitudinal direction, a new type of structural element is suggested which is expected to serve as pier with reasonable efficiency. Rigidity at bottom is not much needed if piers act as a whole, being framed by top capping beam. S.K. Kundoo and B.B. Maiti
At present, the requirements for structural concrete are specified in five different Codes of Practice. These Codes have been drafted at different times and it is not surprising that they differ considerably in those sections related to the specification and production of the concrete. This paper describes the development of the requirements for concrete in the Codes from 1934 to 1965. D.C. Teychenné
A message of congratulations and good wishes to the 13,000 members of the Institution from HRH Prince Philip, an Honorary Member, was read to the 400 guests who assembled at the Luncheon at the Dorchester Hotel in London on 20 March last to mark the 60th Anniversary of the Institution's formation in 1908. Among the many distinguished guests were Professor Pier Luigi Nervi and his wife who were making one of their rare visits to London for the occasion.
