Professor A.L.L. Baker, who represents the Institution of Structural Engineers, Institution of Civil Engineers, Reinforced Concrete Association and Cement and Concrete Association on the European Concrete Committee (CEB), reports on a meeting
of the Committee held in Ankara last September.
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.

Dr. D. D. Matthews (Past President): In my view the answer to the question raised in the title of this evening’s paper is a simple affirmative. Dr. Beeby has raised a number of interesting points and treated them in a workmanlike manner. He points out the inconsistencies in the way one-way spans are treated, particularly in comparison with two-way slabs supported along their edges, and, to a lesser extent, flat slabs.
