Wednesday 4 May 1994 is the 60th anniversary of the granting of the Royal Charter. On the day, the anniversary is being commemorated by holding a l-day seminar on the history and development of structural design at The Brewery, Chiswell Street, London EC1Y 4SD. Nine Institution Gold Medallists are participating in the seminar, and summaries of their papers are given below. The proceedings of the seminar are scheduled for publication in book form in December 1994.
Structural engineering as a separate branch of civil engineering owes its advent early this century to the specialised knowledge required to design structures and, in particular, reinforced concrete structures. S.B. Tietz and J.A. Waller
On 4 May 1934, as the Institution was granted its Royal Charter, leading engineers could look back over their careers to see the extraordinary development of a whole range of promising new material technologies for building the infrastructure. The use of structural steel with riveted connections had become well established, and both bolted and site welded connections had been developed and were being tried out. Reinforced concrete construction was being widely used, and Freyssinet, having just completed the Plougastel Bridge in Brittany, had developed his prestressing system and was setting up manufacturing facilities for precast prestressed beams. The George Washington Suspension Bridge, with a mainspan of 1067 m, had just been successfully completed, showing the full benefits of high strength steel wire, and the Golden Gate Bridge, with a mainspan of 1280 m, was under construction. The world’s tallest building, the Empire State, had also recently been finished. P.R. Head
