The President 1973-74

Just as the structure of the Sydney Opera House is unique in its shape and overall complexity, so are the glass walls which enclose the building. Many of the problems encountered in the design and construction of the walls were entirely without precedent, and had therefore to be solved from first principles. D.D. Croft and J.A. Hooper

In this paper is summarized the development of a rational method for the plastic design of biaxially loaded steel columns which is sufficiently compact for inclusion in structural codes of practice. The study takes account of previous work on flexural and flexural-torsional buckling of columns and fills in some of the gaps where knowledge is lacking. The effects of local buckling are not considered. B.W. Young

Routine checking The task of checking the work of another structural engineer is becoming an increasingly frequent one for members of the Institution. It is a trend to be welcomed but the professional responsibility of an engineer in such checking cannot be over-emphasized.
