Erection of Metallic Bridges

THE CHAIRMAN, Mr. Ewart S. Andrews, who read the paper in the absence of the author, said Mr. Hakin was an Associate Member of the Institution and at present resident in the United States, but he was born and trained in this country. The paper was one of the very best that the Institution had ever had and they would all be proud of the fact that Mr. Hakin was trained in this country.

By courtesy of Mr. R. A. Chattock (the City of Birmingham Electrical Engineer), a large party of members of the Midland Branch visited the Hams Hall Electricity Generating Station on Friday, September 28th, 1928.

To the Editor of The Structural Engineer. “Augmented Steel.” Sir,-Under the above heading you have published an interesting conlmunication of Mr. W. B. Scott, showing what increase of bearing strength could be attained by imbedding steel members in concrete. I find, considered in the above noted article, two forms of such composite members. The “haunched” girder where the effective bearing height of an I beam has been increased by help of a concrete plate (the article gives all details of this composition), and the “composite” column, as it is called in American prescriptions, with a few references to the American practice.
