Abstract: The article is devoted to a consideration of setting wind loads on lattice towers in different standards of the world: the former USSR SNiP (performance requirements) 2.01.07-85, the Ukrainian DBN (performance requirements) В.1.2-2:2006, the European Norms EN 1993-3-1:2006, EN 1991-1-4:2004, the American ASCE 7-05, the British Norms BS 8100-4-1995 and the Canadian Standard CSA S37-94. There are compared normative periods of repeatability of wind velocity, vertical profiles of average velocity pressure, and aerodynamical coefficients of tower spatial sections at the most unfavourable angle of attack of a wind flow. It is shown, therewith, that developers having the norms of a various quantity of an experimental material, of the usage of different criteria for determining design value of quantities, miscalculation of their statistical performance, for using different design factor provisions, for regulation of normative techniques of different hierarchy and accuracy, the variation of their numerical estimate can reach 50%.Keywords: codes of design, wind load, angle of attack, lattice towers, vertical profile of wind, period of repeatability, coefficient of integrity, aerodynamical coefficient.
