My first desire is to thank the members of this Institution most sincerely for the honour they have conferred on me by electing me their President for the Session 1949-50. Conscious as I am of my shortcomings for this high office, I can only promise to serve you to the best of my ability, to endeavour to uphold the high traditions of my predecessors and to try to merit the confidence you have placed in me. Leslie Turner
The design and construction of modern steel and reinforced concrete structures are largely governed by the provisions of the 1948 Editions of B.S.449 and B.S. Code of Practice C.P.114 which replace those of a previous decade. The progress reflected in these documents is reviewed in the light of their contribution to steel economy and a comparison is made of the steel required for a number of alternative structural examples. Brief consideration is given to some aspects which require clarification or further research and to the direction of future advances. L.R. Creasy
The authors have presented an interesting method for the rapid estimation of maximum bending moments in decks of suspension bridges. Their approximate analysis draws to a logical conclusion the more general method described by Bowen and Charlton (reference 3 of the paper). It is clear that the use of symmetry and antisymmetry offers a considerable computational advantage :two sets of three linear simultaneous equations are solved far more quickly than one set of six.
