THE PRESIDENT, introducing the lecturers, said he had known Professor Sparkes very well for many years. After graduating at the University of Bristol in 1932, he had worked for Dorman Long & Co., Ltd., where he had learned much about structural steelwork. Col. Kirkland remembered him there, particularly for his most brilliant handling of a compound loading problem solved by calculus. He had shown Professor Sparkes an arithmetical solution ; since then he had been a most able collaborator and a very dear friend. The Authors presented the paper, which was illustrated by many slides.
Simply-supported bridge-decks are frequently designed as grillages so that the interaction between longitudinal main members can assist the load distribution when the deck has to carry the abnormal heavy vehicle (the H.B. loading of B.S.153). The analysis of simply-supported single-span grillages is now well established by the use of the ‘ quasi ’ slab technique. In recent years the number of continuous or otherwise statically-indeterminate bridge decksparticularly in prestressed concrete-has been increasing and where continuous decks have been adopted they have often been constructed with beams of varying depth and section properties. A demand has, therefore, arisen for an analytical technique for such continuous grillages. A. Goldstein, E. Lightfoot and F. Sawko
Nearly three years after they were introduced, to what extent are Eurocodes really being implemented in the UK? CSC's Chief Engineer, Alan Rathbone, discusses the progress the industry has made to date and encourages UK engineers to be at the forefront of these changes.
