The Structural Engineer, Volume 41, Issue 9, 1963
Theoretical Investigation An approximate general solution1 has been presented for contact pressures of finite beams resting on idealized models of the soil. The foundation models treated include :- (a) Winkler model of isolated springs; (b) homogeneous anisotropic half-space, isotropy being a special case (c) non-homogeneous half-space, compressibility decreasing with depth LAING BARDEN
In the investigation of the behaviour of arches the forms most often considered are the parabola and the circle, whilst from a practical aspect the parabola is the most usual form. The elementary theory of the parabolic arch is not difficult but in more advanced analysis it may be convenient to consider the arch as a sine curve. The brief analysis outlined below compares the behaviour of a suitably chosen sine curve with that of a given parabolic arch with regard to some of the more familiar properties of the latter. H.

Introducing his paper Mr. Weiss said that there was certainly one theme at least which might provoke an interesting discussion: in this almost completely unadorned theatre architecture and engineering had been compelled to find a common expression, architect and engineer had had to be tuned in to the same wavelength. How had this been achieved, and was the final product successful? He hoped that his friend, Mr. Philip Powell, who was present, would give his views on this as he was so much better able to do this than Mr. Weiss.
