Hydro-Electric Developments - Pitlochry. Discussion of Mr. J Guthrie Brown’s Paper

From Mr. D. L. LITTLE : As a visitor I should like to thank the Institution very much indeed for inviting me to hear Professor Baker give his paper.

Sir, In this paper, Mr. Robson considers the effect on bending moments when the change of moment of inertia along a continuous reinforced concrete beam is taken into account. Changes are assumed to occur where the bending moment changes sign, and the calculations are based on the ratio of the moment of inertia of a plain concrete tee beam for sagging moment, and a rectangular beam for hogging moment.

As announced in the April issue of the Journal, the President and the Secretary left Southampton on March 30th to visit the Union of South Africa Branch. This was the first visit by officials of the Institution to the Branch since its formation in 1937, and both were greatly impressed by the progress which the Branch has made during its comparatively short history and by the enthusiasm of its members, as well as deeply moved by the warmth of the welcome accorded them.
