I should like to thank Dr. Rangasami and Dr. Kaburu for their Technical Note, which has assisted me in some practical engineering research in the field of braced domes and vaults.
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.
Block and brickwork are current subjects of correspondence from members. Mr. R. J. Rhodes raises what must be a fairly common problem : As it can prove extremely difficult, if not impossible, to prove on paper that brickwork structures, however
simple, will stand up, it is essential that any assistance from internal pressure must be utilised.
