If the chimney is surroundedby buildings, this would of course act onlyabove the roof. In designing Weber coniform chimneys,a high factor of safety is allowed and lowstresses are calculated on both steel andconcrete, resulting in a very conserva-tive design. The calculations used in de-signing Weber coniform chimneys arebased on the formula of Turneaure &Maurer (F. E. Turneaure, dean of the Col-lege of Engineering, University of Wiscon-sin, and E. R. Maurer, professor of me-chanics, University of Wisconsin), as pub-lished in Principles of Reinforced Con-crete Construction, second edition, page398, who are considered the highest au-thority on this subject.
