We, the Council of the Chartered Institution of Structural Engineers, on our own behalf and that of the members of the Institution desire humbly to tender our most sincere and heartfelt congratulations on the occasion of the Twenty-fifth Anniversary of the Marriage of your Gracious Majesty and her Majesty Queen Elizabeth.
A typescript copy of this paper (3,000 words with two tables and four figures) is available in the Library of the Institution. The paper is revolutionary in its views of the fundamentals of the strength of steel. A.C. Vivian
The possibility of multi-storey buildings being constructed in the near future with light pre-fabricated internal partitions makes it important to ensure that wind stresses are correctly calculated. The American practice of assuming the points of contraflexure in the stanchions to be mid-way between the floors can involve serious errors and the continental practice of using three member equations is a little too laborious in the case of high buildings. Professor A.L.L. Baker
Professor A. L. L,. Baker, in his simple solution for wind stresses in multi-storey buildings, aims at defining the limits in any stanchion within which the point of contraflexure must lie. This enables safe estimates to be made or bending moments due to wind load in both stanchions and beams. The theory is based upon the analysis of a single bay multistorey frame with equal storey heights and equal beams, and would only apply strictly to such a building. The solution also assumes that the joints are completely rigid. However, the extreme ease with which the theory may be applied when only the barest outline of the design is settled makes it attractive, and prompts investigation into what happens when the conditions laid down in the simple analysis are not satisfied.
