EFFECT OF WIND
BUILDING CONSTRUCTION TESTS DAMAGE BY SUCTION. (From Our Own Correspondent.) LONDON, January 23. Gale tests are'being carried on by the National Physical Laboratory which may lead to important advances in building design. Mr A. Bailey, one of the staff, is making his tests in a large shod near Manchester and on the wind-swept Severn viaduct near Berkeley, Gloucestershire, He is making use of a scries of pressure gauges connected to small holes in different parts of the building. When the gauges indicated a high gust of wind a flashlight photograph was taken showing the distribution of wind pressure. The results were afterwards confirmed from measurements made on a small scale model of the building, which was exposed to an artificial gale in a “ wind tunnel ” at the laboratory. The measurements prove that suction on the far side of a building is the most important element in gale damage. Further confirmation is provided by photographs of gale damage at Birmingham. One of these photographs shows the entire wall of a house was pulled outwards by suction on the leeward side. Other photographs show how the roof was lifted from a row of 10 houses, also a suction effect.
Mr Bailey maintains that a curved or hemispherical roof would reduce t.h» wind suction.
