Over the past few months valuable and stimulating contributions to the subject of structural stability have been made by Professors Bolton and Horne. They observe that the subject is one which structural engineers have difficulty in understanding. In the present discussion the sources of this difficulty are considered. The fundamental prepositions of classical mechanics which govern all such phenomenon in conservative systems are stated, and the application of these to the problems given by Bolton and Horne are given. Finally some comments are included on modern stability theory for
non-conservative systems, and, how current research is attempting to use these to solve some practical engineering problems.
The main changes incorporated in the recent revision of the Code of Practice for Liquid Retaining Structures, BS 5337 (1976) are discussed, together with the reasons for these changes as compared with the previous Code CP published in 1960.
Excessive cracking due to early thermal and shrinkage movement was a common defect in water retaining structures designed to CP2007: 1970 which shouldbe rectified by the new Code. The paper therefore discusses design in accordance with BS 5337: 1976 for satisfactory control of this form of cracking, and outlines the various design options which are available.
