The Restoration of Ancient Buildings. Discussion on the paper by E. W. H. Gifford BSc MIStructE MICE

The paper describes the design, fabrication and erection of the welded steel box girders and concrete deck slab which form the composite superstructure of the bridge. The reasons for the various design features are stated. Mention is made of the use of models for the design stage and the results of a quarter-size model test to destruction are given. The welding procedure is outlined and the method of erection of the girders is explained. The routine tests carried out to check the quality of materials and workmanship are enumerated. Various features of the superstructure are then described and the paper concludes with an indication of possible developments in composite design. W.A. Fairhurst and A. Beveridge
