Abstract
J. F. SHIPLEY, in a paper read in London before the Institution of Electrical Engineers on May 6, points out that the British Standards Institution has recently issued recommendations on this subject which constitute the first authoritative general guidance made available to the public in Great Britain since the Report of the Lightning Rod Conference in 1881 and its amendment by the Lightning Research Committee in 1905. These new recommendations have been adopted by the Ministry of Works and Planning as its first code of practice, the latter containing additional appendixes in which comment is made on some of the new features dealt with, and which the present paper amplifies to some extent. The paper is confined to problems connected with the protection of modern steel-framed and ferroconcrete structures. The need for protection is discussed and a rough attempt is made to assess the lightning risk attached to any structure in any part of the world. The zone of protection receives attention and the presence of metallic systems in the buildings is mentioned ; while the needs of structures which are very vulnerable to lightning, and of others which present difficult problems, are discussed. The components of a lightning protective system, their materials, dimensions and cost are referred to, and finally inspection, testing and records are dealt with.
