Sir, In your issue of August, 1949, No. 8, I found a report of a discussion on Dr. H. Gottfeldt’s paper, “Curved Bridges-and why they should be welded.” From this report I learned that during the discussion the author and Mr. Cadwell expressed some apprehensions as to certain details of a Swedish curved steel bridge mentioned in Dr. Gottfeldt’s paper. Being responsible for the design of this bridge, which belongs to the Swedish State Railways, I feel obliged to inform you that the remarks seem to be based on misunderstandings and incomplete information.
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
