- Abstract
Some of the developments in structural analysis and design over the past twenty years or so are discussed. The paper opens with a reference to elastic methods of analysis of pin-jointed frameworks, and describes a direct method of design of frameworks with redundant members. The elastic analysis of unbraced rigid-jointed frames is then considered, and some recent developments in structural form, such as cellular and shell construction, are mentioned.
A reference to riveted joints serves to show that the present interest in the post-elastic behaviour of structures and their ultimate strength is a logical, though not entirely novel, development in the search for more rational design methods. Design based on conditions at collapse is usually simpler and more economical than conventional elastic design procedures, and has the great advantage in redundant structures of being direct : recent relevant research on triangulated frameworks, rigid steel frames and reinforced concrete frames, shells and slabs is described.
The paper concludes with a discussion of the most neglected aspect of structural design - the margin of safety which should be provided - and some of the directions in which opinion is developing are indicated. Finally a reference is made to the position of Australia in regard to structural research.
